# Terraform CLI Documentation
|
||||
|
||||
Welcome to the Terraform CLI documentation!
|
||||
> **Hands-on:** Try the [Terraform: Get Started](https://learn.hashicorp.com/collections/terraform/aws-get-started?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS) collection on HashiCorp Learn.
|
||||
|
||||
## What's in This Section of the Docs?
|
||||
This is the documentation for Terraform CLI. It is relevant to anyone working
|
||||
with Terraform's CLI-based workflows; this includes people who use Terraform CLI
|
||||
by itself, as well as those who use Terraform CLI in conjunction with Terraform
|
||||
Cloud or Terraform Enterprise.
|
||||
|
||||
This section contains reference documentation for Terraform's core open source
|
||||
features, including the
|
||||
[configuration language](/docs/configuration/index.html), the
|
||||
[command-line tools](/docs/commands/index.html), and the main
|
||||
[Terraform providers](/docs/providers/index.html). Use the navigation sidebar
|
||||
to browse the various subsections.
|
||||
|
||||
## Who is This For?
|
||||
|
||||
The Terraform CLI docs are relevant to _all Terraform users,_ including open
|
||||
source users and Terraform Cloud users.
|
||||
|
||||
Since these docs are reference material, they are mainly written for
|
||||
_intermediate and advanced users,_ who need to find complete and detailed
|
||||
information quickly.
|
||||
|
||||
- **New user?** Try the
|
||||
[Get Started collection](https://learn.hashicorp.com/collections/terraform/aws-get-started?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS)
|
||||
at HashiCorp Learn, then return
|
||||
here once you've used Terraform to manage some simple resources.
|
||||
- **Curious about Terraform?** See [Introduction to Terraform](/intro/index.html)
|
||||
for a broad overview of what Terraform is and why people use it.
|
||||
|
||||
## What's Elsewhere?
|
||||
|
||||
This is not the only section of the Terraform docs! You can find out more at the
|
||||
[Terraform docs home page](/docs/index.html), or you can jump between sections
|
||||
using the "Other Docs" area of the navigation sidebar.
|
||||
Notably, this documentation does not cover the syntax and usage of the Terraform
|
||||
language. For that, see the
|
||||
[Terraform Language Documentation](/docs/configuration/index.html).

# CLI Authentication

|
||||
|
||||
[Terraform Cloud](/docs/cloud/index.html) and
|
||||
[Terraform Enterprise](/docs/enterprise/index.html) are platforms that perform
|
||||
Terraform runs to provision infrastructure, offering a collaboration-focused
|
||||
environment that makes it easier for teams to use Terraform together. (For
|
||||
expediency, the content below refers to both products as "Terraform Cloud.")
|
||||
|
||||
Terraform CLI integrates with Terraform Cloud in several ways — it can be a
|
||||
front-end for [CLI-driven runs](/docs/cloud/run/cli.html) in Terraform Cloud,
|
||||
and can also use Terraform Cloud as a state backend and a private module
|
||||
registry. All of these integrations require you to authenticate Terraform CLI
|
||||
with your Terraform Cloud account.
|
||||
|
||||
The best way to handle CLI authentication is with the `login` and `logout`
|
||||
commands, which help automate the process of getting an API token for your
|
||||
Terraform Cloud user account.
|
||||

||||

# Writing and Modifying Terraform Code
|
||||
|
||||
The [Terraform language](/docs/configuration/index.html) is Terraform's primary
|
||||
user interface, and all of Terraform's workflows rely on configurations written
|
||||
in the Terraform language.
|
||||
|
||||
Terraform CLI includes several commands to make Terraform code more convenient
|
||||
to work with. Integrating these commands into your editing workflow can
|
||||
potentially save you time and effort.
|
||||
|
||||
- [The `terraform console` command](/docs/commands/console.html) starts an
|
||||
interactive shell for evaluating Terraform
|
||||
[expressions](/docs/configuration/expressions.html), which can be a faster way
|
||||
to verify that a particular resource argument results in the value you expect.
|
||||
|
||||
|
||||
- [The `terraform fmt` command](/docs/commands/fmt.html) rewrites Terraform
|
||||
configuration files to a canonical format and style, so you don't have to
|
||||
waste time making minor adjustments for readability and consistency. It works
|
||||
well as a pre-commit hook in your version control system.
|
||||
|
||||
- [The `terraform validate` command](/docs/commands/validate.html) validates the
|
||||
syntax and arguments of the Terraform configuration files in a directory,
|
||||
including argument and attribute names and types for resources and modules.
|
||||
The `plan` and `apply` commands automatically validate a configuration before
|
||||
performing any other work, so `validate` isn't a crucial part of the core
|
||||
workflow, but it can be very useful as a pre-commit hook or as part of a
|
||||
continuous integration pipeline.
|
||||
|
||||
- [The `0.13upgrade` command](/docs/commands/0.13upgrade.html) and
|
||||
[the `0.12upgrade` command](/docs/commands/0.12upgrade.html) can automatically
|
||||
modify the configuration files in a Terraform module to help deal with major
|
||||
syntax changes that occurred in the 0.13 and 0.12 releases of Terraform. Both
|
||||
of these commands are only available in the Terraform version they are
|
||||
associated with, and you are expected to upgrade older code to be compatible
|
||||
with 0.12 before attempting to make it compatible with 0.13. For more detailed
|
||||
information about updating code for new Terraform versions, see the [upgrade
|
||||
guides](/upgrade-guides/index.html) in the Terraform language docs.

# CLI Configuration
|
||||
|
||||
Terraform CLI can be configured with some global settings, which are separate
|
||||
from any Terraform configuration and which apply across all working directories.
|
||||
|
||||
We've designed Terraform such that an average user running Terraform CLI
|
||||
interactively will not need to interact with any of these settings. As a result,
|
||||
most of the global settings relate to advanced or automated workflows, or
|
||||
unusual environmental conditions like running Terraform on an airgapped
|
||||
instance.
|
||||
|
||||
- The [CLI config file](/docs/commands/cli-config.html) configures provider
|
||||
installation and security features.
|
||||
- Several [environment variables](/docs/commands/environment-variables.html) can
|
||||
configure Terraform's inputs and outputs; this includes some alternate ways to
|
||||
provide information that is usually passed on the command line or read from
|
||||
the state of the shell.

|

|

# Initializing Working Directories
|
||||
|
||||
Terraform expects to be invoked from a working directory that contains
|
||||
configuration files written in
|
||||
[the Terraform language](/docs/configuration/index.html). Terraform uses
|
||||
configuration content from this directory, and also uses the directory to store
|
||||
settings, cached plugins and modules, and sometimes state data.
|
||||
|
||||
A working directory must be initialized before Terraform can perform any
|
||||
operations in it (like provisioning infrastructure or modifying state).
|
||||
|
||||
## Working Directory Contents
|
||||
|
||||
A Terraform working directory typically contains:
|
||||
|
||||
- A Terraform configuration describing resources Terraform should manage. This
|
||||
configuration is expected to change over time.
|
||||
- A hidden `.terraform` directory, which Terraform uses to manage cached
|
||||
provider plugins and modules, record which
|
||||
[workspace](/docs/cli/workspaces/index.html) is currently active, and
|
||||
record the last known backend configuration in case it needs to migrate state
|
||||
on the next run. This directory is automatically managed by Terraform, and is
|
||||
created during initialization.
|
||||
- State data, if the configuration uses the default `local` backend. This is
|
||||
managed by Terraform in a `terraform.tfstate` file (if the directory only uses
|
||||
the default workspace) or a `terraform.tfstate.d` directory (if the directory
|
||||
uses multiple workspaces).
|
||||
|
||||
## Initialization
|
||||
|
||||
Run the `terraform init` command to initialize a working directory that contains
|
||||
a Terraform configuration. After initialization, you will be able to perform
|
||||
other commands, like `terraform plan` and `terraform apply`.
|
||||
|
||||
If you try to run a command that relies on initialization without first
|
||||
initializing, the command will fail with an error and explain that you need to
|
||||
run init.
|
||||
|
||||
Initialization performs several tasks to prepare a directory, including
|
||||
accessing state in the configured backend, downloading and installing provider
|
||||
plugins, and downloading modules. Under some conditions (usually when changing
|
||||
from one backend to another), it might ask the user for guidance or
|
||||
confirmation.
|
||||
|
||||
For details, see [the `terraform init` command](/docs/commands/init.html).
|
||||
|
||||
## Reinitialization
|
||||
|
||||
Certain types of changes to a Terraform configuration can require
|
||||
reinitialization before normal operations can continue. This includes changes to
|
||||
provider requirements, module sources or version constraints, and backend
|
||||
configurations.
|
||||
|
||||
You can reinitialize a directory by running `terraform init` again. In fact, you
|
||||
can reinitialize at any time; the init command is idempotent, and will have no
|
||||
effect if no changes are required.
|
||||
|
||||
If reinitialization is required, any commands that rely on initialization will
|
||||
fail with an error and tell you so.
|
||||
|
||||
## Reinitializing Only Modules
|
||||
|
||||
The `terraform get` command will download modules referenced in the
|
||||
configuration, but will not perform the other required initialization tasks.
|
||||
This command is only useful for niche workflows, and most Terraform users can
|
||||
ignore it in favor of `terraform init`.

# Inspecting Infrastructure
|
||||
|
||||
Terraform configurations and state data include some highly structured
|
||||
information about the resources they manage; this includes dependency
|
||||
information, outputs (which are pieces of generated or discovered data that the
|
||||
configuration's author considers important enough to surface to users), and
|
||||
more.
|
||||
|
||||
Terraform CLI includes some commands for inspecting or transforming this data.
|
||||
You can use these to integrate other tools with Terraform's infrastructure data,
|
||||
or just to gain a deeper or more holistic understanding of your infrastructure.
|
||||
|
||||
- [The `terraform graph` command](/docs/commands/graph.html) creates a visual
|
||||
representation of a configuration or a set of planned changes.
|
||||
- [The `terraform output` command](/docs/commands/output.html) can get the
|
||||
values for the top-level [output values](/docs/configuration/outputs.html) of
|
||||
a configuration, which are often helpful when making use of the infrastructure
|
||||
Terraform has provisioned.
|
||||
- [The `terraform show` command](/docs/commands/show.html) can generate
|
||||
human-readable versions of a state file or plan file, or generate
|
||||
machine-readable versions that can be integrated with other tools.
|
||||
- [The `terraform state list` command](/docs/commands/state/list.html) can list
|
||||
the resources being managed by the current working directory and workspace,
|
||||
providing a complete or filtered list.
|
||||
- [The `terraform state show` command](/docs/commands/state/show.html) can print
|
||||
all of the attributes of a given resource being managed by the current working
|
||||
directory and workspace, including generated read-only attributes like the
|
||||
unique ID assigned by the cloud provider.

|

|

# Managing Plugins
|
||||
|
||||
Terraform relies on plugins called "providers" in order to manage various types
|
||||
of resources. (For more information about providers, see
|
||||
[Providers](/docs/configuration/blocks/providers/index.html) in the Terraform
|
||||
language docs.)
|
||||
|
||||
-> **Note:** Providers are currently the only plugin type most Terraform users
|
||||
will interact with. Terraform also supports third-party provisioner plugins, but
|
||||
we discourage their use.
|
||||
|
||||
Terraform downloads and/or installs any providers
|
||||
[required](/docs/configuration/provider-requirements.html) by a configuration
|
||||
when [initializing](/docs/cli/init/index.html) a working directory. By default,
|
||||
this works without any additional interaction but requires network access to
|
||||
download providers from their source registry.
|
||||
|
||||
You can configure Terraform's provider installation behavior to limit or skip
|
||||
network access, and to enable use of providers that aren't available via a
|
||||
networked source. Terraform also includes some commands to show information
|
||||
about providers and to reduce the effort of installing providers in airgapped
|
||||
environments.
|
||||
|
||||
## Configuring Plugin Installation
|
||||
|
||||
Terraform's configuration file includes options for caching downloaded plugins,
|
||||
or explicitly specifying a local or HTTPS mirror to install plugins from. For
|
||||
more information, see [CLI Config File](/docs/commands/cli-config.html).
|
||||

||||

Use the [`terraform providers`](/docs/commands/providers.html) command to get information
|
||||
about the providers required by the current working directory's configuration.
|
||||
|
||||
Use the [`terraform providers schema`](/docs/commands/providers/schema.html) command to
|
||||
get machine-readable information about the resources and configuration options
|
||||
offered by each provider.
|
||||
|
||||
## Managing Plugin Installation
|
||||
|
||||
Use the [`terraform providers mirror`](/docs/commands/providers/mirror.html) command to
|
||||
download local copies of every provider required by the current working
|
||||
directory's configuration. This directory will use the nested directory layout
|
||||
that Terraform expects when installing plugins from a local source, so you can
|
||||
transfer it directly to an airgapped system that runs Terraform.
|
||||
|
||||
Use the [`terraform providers lock`](/docs/commands/providers/lock.html) command
|
||||
to update the lock file that Terraform uses to ensure predictable runs when
|
||||
using ambiguous provider version constraints.

# Provisioning Infrastructure with Terraform
|
||||
|
||||
Terraform's primary function is to create, modify, and destroy infrastructure
|
||||
resources to match the desired state described in a
|
||||
[Terraform configuration](/docs/configuration/index.html).
|
||||
|
||||
When people refer to "running Terraform," they generally mean performing these
|
||||
provisioning actions in order to affect real infrastructure objects. The
|
||||
Terraform binary has many other subcommands for a wide variety of administrative
|
||||
actions, but these basic provisioning tasks are the core of Terraform.
|
||||
|
||||
Terraform's provisioning workflow relies on three commands: `plan`, `apply`, and
|
||||
`destroy`. All of these commands require an
|
||||
[initialized](/docs/cli/init/index.html) working directory, and all of them act
|
||||
only upon the currently selected [workspace](/docs/cli/workspaces/index.html).
|
||||
|
||||
## Planning
|
||||
|
||||
The `terraform plan` command evaluates a Terraform configuration to determine
|
||||
the desired state of all the resources it declares, then compares that desired
|
||||
state to the real infrastructure objects being managed with the current working
|
||||
directory and workspace. It uses state data to determine which real objects
|
||||
correspond to which declared resources, and checks the current state of each
|
||||
resource using the relevant infrastructure provider's API.
|
||||
|
||||
Once it has determined the difference between the current state and the desired
|
||||
state, `terraform plan` presents a description of the changes necessary to
|
||||
achieve the desired state. It _does not_ perform any actual changes to real
|
||||
world infrastructure objects; it only presents a plan for making changes.
|
||||
|
||||
Plans are usually run to validate configuration changes and confirm that the
|
||||
resulting actions are as expected. However, `terraform plan` can also save its
|
||||
plan as a runnable artifact, which `terraform apply` can use to carry out those
|
||||
exact changes.
|
||||
|
||||
For details, see [the `terraform plan` command](/docs/commands/plan.html).
|
||||
|
||||
## Applying
|
||||
|
||||
The `terraform apply` command performs a plan just like `terraform plan` does,
|
||||
but then actually carries out the planned changes to each resource using the
|
||||
relevant infrastructure provider's API. It asks for confirmation from the user
|
||||
before making any changes, unless it was explicitly told to skip approval.
|
||||
|
||||
By default, `terraform apply` performs a fresh plan right before applying
|
||||
changes, and displays the plan to the user when asking for confirmation.
|
||||
However, it can also accept a plan file produced by `terraform plan` in lieu of
|
||||
running a new plan. You can use this to reliably perform an exact set of
|
||||
pre-approved changes, even if the configuration or the state of the real
|
||||
infrastructure has changed in the minutes since the original plan was created.
|
||||
|
||||
For details, see [the `terraform apply` command](/docs/commands/apply.html).
|
||||
|
||||
## Destroying
|
||||
|
||||
The `terraform destroy` command destroys all of the resources being managed by
|
||||
the current working directory and workspace, using state data to determine which
|
||||
real world objects correspond to managed resources. Like `terraform apply`, it
|
||||
asks for confirmation before proceeding.
|
||||
|
||||
A destroy behaves exactly like deleting every resource from the configuration
|
||||
and then running an apply, except that it doesn't require editing the
|
||||
configuration. This is more convenient if you intend to provision similar
|
||||
resources at a later date.
|
||||
|
||||
For details, see [the `terraform destroy` command](/docs/commands/destroy.html).

# Manipulating Terraform State
|
||||
|
||||
Terraform uses [state data](/docs/state/index.html) to remember which
|
||||
real-world object corresponds to each resource in the configuration;
|
||||
this allows it to modify an existing object when its resource declaration
|
||||
changes.
|
||||
|
||||
Terraform updates state automatically during plans and applies. However, it's
|
||||
sometimes necessary to make deliberate adjustments to Terraform's state data,
|
||||
usually to compensate for changes to the configuration or the real managed
|
||||
infrastructure.
|
||||
|
||||
Terraform CLI supports several workflows for interacting with state:
|
||||
|
||||
- [Inspecting State](/docs/cli/state/inspect.html)
|
||||
- [Forcing Re-creation (Tainting)](/docs/cli/state/taint.html)
|
||||
- [Moving Resources](/docs/cli/state/move.html)
|
||||
- Importing Pre-existing Resources (documented in the
|
||||
[Importing Infrastructure](/docs/import/index.html) section)
|
||||
- [Disaster Recovery](/docs/cli/state/recover.html)
|
||||
|
||||
~> **Important:** Modifying state data outside a normal plan or apply can cause
|
||||
Terraform to lose track of managed resources, which might waste money, annoy
|
||||
your colleagues, or even compromise the security of your operations. Make sure
|
||||
to keep backups of your state data when modifying state out-of-band.

|

- [The `terraform state show` command](/docs/commands/state/show.html)

||||
done automatically during plans and applies, but not when interacting with

# Moving Resources
|
||||
|
||||
Terraform's state associates each real-world object with a configured resource
|
||||
at a specific [resource address](/docs/internals/resource-addressing.html). This
|
||||
is seamless when changing a resource's attributes, but Terraform will lose track
|
||||
of a resource if you change its name, move it to a different module, or change
|
||||
its provider.
|
||||
|
||||
Usually that's fine: Terraform will destroy the old resource, replace it with a
|
||||
new one (using the new resource address), and update any resources that rely on
|
||||
its attributes.
|
||||
|
||||
In cases where it's important to preserve an existing infrastructure object, you
|
||||
can explicitly tell Terraform to associate it with a different configured
|
||||
resource.
|
||||
|
||||
- [The `terraform state mv` command](/docs/commands/state/mv.html) changes
|
||||
which resource address in your configuration is associated with a particular
|
||||
real-world object. Use this to preserve an object when renaming a resource, or
|
||||
when moving a resource into or out of a child module.
|
||||
|
||||
- [The `terraform state rm` command](/docs/commands/state/rm.html) tells
|
||||
Terraform to stop managing a resource as part of the current working directory
|
||||
and workspace, _without_ destroying the corresponding real-world object. (You
|
||||
can later use `terraform import` to start managing that resource in a
|
||||
different workspace or a different Terraform configuration.)
|
||||
|
||||
- [The `terraform state replace-provider` command](/docs/commands/state/replace-provider.html)
|
||||
transfers existing resources to a new provider without requiring them to be
|

re-created.

# Forcing Re-creation of Resources (Tainting)
|
||||
|
||||
When a resource declaration is modified, Terraform usually attempts to update
|
||||
the existing resource in place (although some changes can require destruction
|
||||
and re-creation, usually due to upstream API limitations).
|
||||
|
||||
In some cases, you might want a resource to be destroyed and re-created even
|
||||
when Terraform doesn't think it's necessary. This is usually for objects that
|
||||
aren't fully described by their resource arguments due to side-effects that
|
||||
happen during creation; for example, a virtual machine that configures itself
|
||||
with `cloud-init` on startup might no longer meet your needs if the cloud-init
|
||||
configuration changes.
|
||||
|
||||
- [The `terraform taint` command](/docs/commands/taint.html) tells Terraform to
|
||||
destroy and re-create a particular resource during the next apply, regardless
|
||||
of whether its resource arguments would normally require that.
|
||||
|
||||
- [The `terraform untaint` command](/docs/commands/untaint.html) undoes a
|
||||
previous taint, or can preserve a resource that was automatically tainted due
|
||||
to failed [provisioners](/docs/provisioners/index.html).

# Managing Workspaces
|
||||
|
||||
In Terraform CLI, _workspaces_ are separate instances of
|
||||
[state data](/docs/state/index.html) that can be used from the same working
|
||||
directory. You can use workspaces to manage multiple non-overlapping groups of
|
||||
resources with the same configuration.
|
||||
|
||||
- Every [initialized working directory](/docs/cli/init/index.html) has at least
|
||||
one workspace. (If you haven't created other workspaces, it is a workspace
|
||||
named `default`.)
|
||||
- For a given working directory, only one workspace can be _selected_ at a time.
|
||||
- Most Terraform commands (including [provisioning](/docs/cli/run/index.html)
|
||||
and [state manipulation](/docs/cli/state/index.html) commands) only interact
|
||||
with the currently selected workspace.
|
||||
- Use [the `terraform workspace select` command](/docs/commands/workspace/select.html)
|
||||
to change the currently selected workspace.
|
||||
- Use the [`terraform workspace list`](/docs/commands/workspace/list.html),
|
||||
[`terraform workspace new`](/docs/commands/workspace/new.html), and
|
||||
[`terraform workspace delete`](/docs/commands/workspace/delete.html) commands
|
||||
to manage the available workspaces in the current working directory.
|
||||
|
||||
-> **Note:** Terraform Cloud and Terraform CLI both have features called
|
||||
"workspaces," but they're slightly different. Terraform Cloud's workspaces
|
||||
behave more like completely separate working directories.
|
||||
|
||||
## The Purpose of Workspaces
|
||||
|
||||
Since most of the resources you can manage with Terraform don't include a unique
|
||||
name as part of their configuration, it's common to use the same Terraform
|
||||
configuration to provision multiple groups of similar resources.
|
||||
|
||||
Terraform relies on [state](/docs/state/index.html) to associate resources with
|
||||
real-world objects, so if you run the same configuration multiple times with
|
||||
completely separate state data, Terraform can manage many non-overlapping groups
|
||||
of resources. In some cases you'll want to change
|
||||
[variable values](/docs/configuration/variables.html) for these different
|
||||
resource collections (like when specifying differences between staging and
|
||||
production deployments), and in other cases you might just want many instances
|
||||
of a particular infrastructure pattern.
|
||||
|
||||
The simplest way to maintain multiple instances of a configuration with
|
||||
completely separate state data is to use multiple
|
||||
[working directories](/docs/cli/init/index.html) (with different
|
||||
[backend](/docs/configuration/backend.html) configurations per directory, if you
|
||||
aren't using the default `local` backend).
|
||||
|
||||
However, this isn't always the most _convenient_ way to handle separate states.
|
||||
Terraform installs a separate cache of plugins and modules for each working
|
||||
directory, so maintaining multiple directories can waste bandwidth and disk
|
||||
space. You must also update your configuration code from version control
|
||||
separately for each directory, reinitialize each directory separately when
|
||||
changing the configuration, etc.
|
||||
|
||||
Workspaces allow you to use the same working copy of your configuration and the
|
||||
same plugin and module caches, while still keeping separate states for each
|
||||
collection of resources you manage.
|
||||
|
||||
## Interactions with Terraform Cloud Workspaces
|
||||
|
||||
Terraform Cloud organizes infrastructure using workspaces, but its workspaces
|
||||
act more like completely separate working directories; each Terraform Cloud
|
||||
workspace has its own Terraform configuration, set of variable values, state
|
||||
data, run history, and settings.
|
||||
|
||||
These two kinds of workspaces are different, but related. When using Terraform
|
||||
CLI as a frontend for Terraform Cloud, you associate the current working
|
||||
directory with one or more remote workspaces by configuring
|
||||
[the `remote` backend](/docs/backends/types/remote.html). If you associate the
|
||||
directory with multiple workspaces (using a name prefix), you can use the
|
||||
`terraform workspace` commands to select which remote workspace to use.
|
||||
|
||||
For more information about using Terraform CLI with Terraform Cloud, see
|
||||
[CLI-driven Runs](/docs/cloud/run/cli.html) in the Terraform Cloud docs.

# Backends
|
||||
|
||||
Each Terraform configuration can specify a backend, which defines where
|
||||
and how operations are performed, where [state](/docs/state/index.html)
|
||||
snapshots are stored, etc.
|
||||
|
||||
The rest of this page introduces the concept of backends; the other pages in
|
||||
this section document how to configure and use backends.
|
||||
|
||||
- [Backend Configuration](/docs/configuration/backend.html) documents the form
|
||||
of a `backend` block, which selects and configures a backend for a
|
||||
Terraform configuration.
|
||||
- This section also includes a page for each of Terraform's built-in backends,
|
||||
documenting its behavior and available settings. See the navigation sidebar
|
||||
for a complete list.
|
||||
|
||||
## Recommended Backends
|
||||
|
||||
- If you are still learning how to use Terraform, we recommend using the default
|
||||
`local` backend, which requires no configuration.
|
||||
- If you and your team are using Terraform to manage meaningful infrastructure,
|
||||
we recommend using the `remote` backend with [Terraform Cloud](/docs/cloud/index.html)
|
||||
or [Terraform Enterprise](/docs/enterprise/index.html).
|
||||
|
||||
## Where Backends are Used
|
||||
|
||||
Backend configuration is only used by [Terraform CLI](/docs/cli-index.html).
|
||||
Terraform Cloud and Terraform Enterprise always use their own state storage when
|
||||
performing Terraform runs, so they ignore any backend block in the
|
||||
configuration.
|
||||
|
||||
But since it's common to
|
||||
[use Terraform CLI alongside Terraform Cloud](/docs/cloud/run/cli.html)
|
||||
(and since certain state operations, like [tainting](/docs/commands/taint.html),
|
||||
can only be performed on the CLI), we recommend that Terraform Cloud users
|
||||
include a backend block in their configurations and configure the `remote`
|
||||
backend to use the relevant Terraform Cloud workspace(s).
|
||||
|
||||
## Where Backends Come From
|
||||
|
||||
Terraform includes a built-in selection of backends; this selection has changed
|
||||
over time, but does not change very often.
|
||||
|
||||
The built-in backends are the only backends. You cannot load additional backends
|
||||
as plugins.
|
||||
|
||||
## What Backends Do
|
||||
|
||||
There are two areas of Terraform's behavior that are determined by the backend:
|
||||
|
||||
- Where state is stored.
|
||||
- Where operations are performed.
|
||||
|
||||
### State
|
||||
|
||||
Terraform uses persistent [state](/docs/state/index.html) data to keep track of
|
||||
the resources it manages. Since it needs the state in order to know which
|
||||
real-world infrastructure objects correspond to the resources in a
|
||||
configuration, everyone working with a given collection of infrastructure
|
||||
resources must be able to access the same state data.
|
||||
|
||||
The `local` backend stores state as a local file on disk, but every other
|
||||
backend stores state in a remote service of some kind, which allows multiple
|
||||
people to access it. Accessing state in a remote service generally requires some
|
||||
kind of access credentials, since state date contains extremely sensitive
|
||||
information.
|
||||
|
||||
Some backends act like plain "remote disks" for state files; others support
|
||||
_locking_ the state while operations are being performed, which helps prevent
|
||||
conflicts and inconsistencies.
|
||||
|
||||
### Operations
|
||||
|
||||
"Operations" refers to performing API requests against infrastructure services
|
||||
in order to create, read, update, or destroy resources. Not every `terraform`
|
||||
subcommand performs API operations; many of them only operate on state data.
|
||||
|
||||
Only two backends actually perform operations: `local` and `remote`.
|
||||
|
||||
The `local` backend performs API operations directly from the machine where the
|
||||
`terraform` command is run. Whenever you use a backend other than `local` or
|
||||
`remote`, Terraform uses the `local` backend for operations; it only uses the
|
||||
configured backend for state storage.
|
||||
|
||||
The `remote` backend can perform API operations remotely, using Terraform Cloud
|
||||
or Terraform Enterprise. When running remote operations, the local `terraform`
|
||||
command displays the output of the remote actions as though they were being
|
||||
performed locally, but only the remote system requires cloud credentials or
|
||||
network access to the resources being managed.
|
||||
|
||||
Remote operations are optional for the `remote` backend; the settings for the
|
||||
target Terraform Cloud workspace determine whether operations run remotely or
|
||||
locally. If local operations are configured, Terraform uses the `remote` backend
|
||||
for state and the `local` backend for operations, like with the other state
|
||||
backends.

# Modules
|
||||
|
||||
> **Hands-on:** Try the [Reuse Configuration with Modules](https://learn.hashicorp.com/collections/terraform/modules?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS) collection on HashiCorp Learn.
|
||||
|
||||
_Modules_ are containers for multiple resources that are used together. A module
|
||||
consists of a collection of `.tf` and/or `.tf.json` files kept together in a
|
||||
directory.
|
||||
|
||||
Modules are the main way to package and reuse resource configurations with
|
||||
Terraform.
|
||||
|
||||
## The Root Module
|
||||
|
||||
Every Terraform configuration has at least one module, known as its
|
||||
_root module_, which consists of the resources defined in the `.tf` files in
|
||||
the main working directory.
|
||||
|
||||
## Child Modules
|
||||
|
||||
A Terraform module (usually the root module of a configuration) can _call_ other
|
||||
modules to include their resources into the configuration. A module that has
|
||||
been called by another module is often referred to as a _child module._
|
||||
|
||||
Child modules can be called multiple times within the same configuration, and
|
||||
multiple configurations can use the same child module.
|
||||
|
||||
## Published Modules
|
||||
|
||||
In addition to modules from the local filesystem, Terraform can load modules
|
||||
from a public or private registry. This makes it possible to publish modules for
|
||||
others to use, and to use modules that others have published.
|
||||
|
||||
The [Terraform Registry](https://registry.terraform.io/browse/modules) hosts a
|
||||
broad collection of publicly available Terraform modules for configuring many
|
||||
kinds of common infrastructure. These modules are free to use, and Terraform can
|
||||
download them automatically if you specify the appropriate source and version in
|
||||
a module call block.
|
||||
|
||||
Also, members of your organization might produce modules specifically crafted
|
||||
for your own infrastructure needs. [Terraform Cloud](/docs/cloud/index.html) and
|
||||
[Terraform Enterprise](/docs/enterprise/index.html) both include a private
|
||||
module registry for sharing modules internally within your organization.
|
||||
|
||||
## Using Modules
|
||||
|
||||
- [Module Blocks](/docs/configuration/modules.html) documents the syntax for
|
||||
calling a child module from a parent module, including meta-arguments like
|
||||
`for_each`.
|
||||
- [Module Sources](/docs/modules/sources.html) documents what kinds of paths,
|
||||
addresses, and URIs can be used in the `source` argument of a module block.
|
||||
|
||||

# Providers
|
||||
|
||||
Terraform relies on plugins called "providers" to interact with remote systems.
|
||||
|
||||
Terraform configurations must declare which providers they require so that
|
||||
Terraform can install and use them. Additionally, some providers require
|
||||
configuration (like endpoint URLs or cloud regions) before they can be used.
|
||||
|
||||
## What Providers Do
|
||||
|
||||
Each provider adds a set of [resource types](/docs/configuration/resources.html)
|
||||
and/or [data sources](/docs/configuration/data-sources.html) that Terraform can
|
||||
manage.
|
||||
|
||||
Every resource type is implemented by a provider; without providers, Terraform
|
||||
can't manage any kind of infrastructure.
|
||||
|
||||
Most providers configure a specific infrastructure platform (either cloud or
|
||||
self-hosted). Providers can also offer local utilities for tasks like
|
||||
generating random numbers for unique resource names.
|
||||
|
||||
## Where Providers Come From
|
||||
|
||||
Providers are distributed separately from Terraform itself, and each provider
|
||||
has its own release cadence and version numbers.
|
||||
|
||||
The [Terraform Registry](https://registry.terraform.io/browse/providers)
|
||||
is the main directory of publicly available Terraform providers, and hosts
|
||||
providers for most major infrastructure platforms.
|
||||
|
||||
## How to Use Providers
|
||||
|
||||
To use resources from a given provider, you need to include some information
|
||||
about it in your configuration. See the following pages for details:
|
||||
|
||||
- [Provider Requirements](/docs/configuration/provider-requirements.html)
|
||||
documents how to declare providers so Terraform can install them.
|
||||
|
||||
- [Provider Configuration](/docs/configuration/providers.html)
|
||||
documents how to configure settings for providers.
|
||||
|
||||
- [Dependency Lock File](/docs/configuration/dependency-lock.html)
|
||||
documents an additional HCL file that can be included with a configuration,
|
||||
which tells Terraform to always use a specific set of provider versions.
|
||||
|
||||
## Provider Installation
|
||||
|
||||
- Terraform Cloud and Terraform Enterprise install providers as part of every run.
|
||||
|
||||
- Terraform CLI finds and installs providers when
|
||||
[initializing a working directory](/docs/cli/init/index.html). It can
|
||||
automatically download providers from a Terraform registry, or load them from
|
||||
a local mirror or cache. If you are using a persistent working directory, you
|
||||
must reinitialize whenever you change a configuration's providers.
|
||||
|
||||
To save time and bandwidth, Terraform CLI supports an optional plugin
|
||||
cache. You can enable the cache using the `plugin_cache_dir` setting in
|
||||
[the CLI configuration file](/docs/commands/cli-config.html).
|
||||
|
||||
To ensure Terraform always installs the same provider versions for a given
|
||||
configuration, you can use Terraform CLI to create a
|
||||
[dependency lock file](/docs/configuration/dependency-lock.html)
|
||||
and commit it to version control along with your configuration. If a lock file
|
||||
is present, Terraform Cloud, CLI, and Enterprise will all obey it when
|
||||
installing providers.
|
||||
|
||||
## How to Find Providers
|
||||
|
||||
To find providers for the infrastructure platforms you use, browse
|
||||
[the providers section of the Terraform Registry](https://registry.terraform.io/browse/providers).
|
||||
|
||||
Some providers on the Registry are developed and published by HashiCorp, some
|
||||
are published by platform maintainers, and some are published by users and
|
||||
volunteers. The provider listings use the following badges to indicate who
|
||||
develops and maintains a given provider.

_Resources_ are the most important element in the Terraform language.
|
||||
Each resource block describes one or more infrastructure objects, such
|
||||
as virtual networks, compute instances, or higher-level components such
|
||||
as DNS records.
|
||||
|
||||
- [Resource Blocks](/docs/configuration/resources.html) documents how to declare
|
||||
resources, including information about meta-arguments like `for_each`.
|
||||
- [Provisioners](/docs/configuration/blocks/resources/provisioners/index.html)
|
||||
documents configuring post-creation actions for a resource using the
|
||||
`provisioner` and `connection` blocks. Since provisioners are non-declarative
|
||||
and potentially unpredictable, we strongly recommend that you treat them as a
|
||||
last resort.

# Variables and Outputs
|
||||
|
||||
The Terraform language includes a few kinds of blocks for requesting or
|
||||
publishing named values.
|
||||
|
||||
- [Input Variables](/docs/configuration/variables.html) serve as parameters for
|
||||
a Terraform module, so users can customize behavior without editing the source.
|
||||
|
||||
- [Output Values](/docs/configuration/outputs.html) are like return values for a
|
||||
Terraform module.
|
||||
|
||||
- [Local Values](/docs/configuration/locals.html) are a convenience feature for
|
||||
assigning a short name to an expression.

# Expressions
|
||||
|
||||
_Expressions_ are used to refer to or compute values within a configuration.
|
||||
The simplest expressions are just literal values, like `"hello"` or `5`,
|
||||
but the Terraform language also allows more complex expressions such as
|
||||
references to data exported by resources, arithmetic, conditional evaluation,
|
||||
and a number of built-in functions.
|
||||
|
||||
Expressions can be used in a number of places in the Terraform language,
|
||||
but some contexts limit which expression constructs are allowed,
|
||||
such as requiring a literal value of a particular type or forbidding
|
||||
[references to resource attributes](/docs/configuration/expressions/references.html#references-to-resource-attributes).
|
||||
Each language feature's documentation describes any restrictions it places on expressions.
|
||||
|
||||
You can experiment with the behavior of Terraform's expressions from
|
||||
the Terraform expression console, by running
|
||||
[the `terraform console` command](/docs/commands/console.html).
|
||||
|
||||
The other pages in this section describe the features of Terraform's
|
||||
expression syntax.

# Files and Directories
|
||||
|
||||
## File Extension
|
||||
|
||||
Code in the Terraform language is stored in plain text files with the `.tf` file
|
||||
extension. There is also
|
||||
[a JSON-based variant of the language](./syntax-json.html) that is named with
|
||||
the `.tf.json` file extension.
|
||||
|
||||
Files containing Terraform code are often called _configuration files._
|
||||
|
||||
## Text Encoding
|
||||
|
||||
Configuration files must always use UTF-8 encoding, and by convention
|
||||
usually use Unix-style line endings (LF) rather than Windows-style
|
||||
line endings (CRLF), though both are accepted.
|
||||
|
||||
## Directories and Modules
|
||||
|
||||
A _module_ is a collection of `.tf` and/or `.tf.json` files kept together in a
|
||||
directory.
|
||||
|
||||
A Terraform module only consists of the top-level configuration files in a
|
||||
directory; nested directories are treated as completely separate modules, and
|
||||
are not automatically included in the configuration.
|
||||
|
||||
Terraform evaluates all of the configuration files in a module, effectively
|
||||
treating the entire module as a single document. Separating various blocks into
|
||||
different files is purely for the convenience of readers and maintainers, and
|
||||
has no effect on the module's behavior.
|
||||
|
||||
A Terraform module can use [module calls](/docs/configuration/modules.html) to
|
||||
explicitly include other modules into the configuration. These child modules can
|
||||
come from local directories (nested in the parent module's directory, or
|
||||
anywhere else on disk), or from external sources like the
|
||||
[Terraform Registry](https://registry.terraform.io).
|
||||
|
||||
## The Root Module
|
||||
|
||||
Terraform always runs in the context of a single _root module._ A complete
|
||||
_Terraform configuration_ consists of a root module and the tree of child
|
||||
modules (which includes the modules called by the root module, any modules
|
||||
called by those modules, etc.).
|
||||
|
||||
- In Terraform CLI, the root module is the working directory where Terraform is
|
||||
invoked. (You can use command line options to specify a root module outside
|
||||
the working directory, but in practice this is rare. )
|
||||
- In Terraform Cloud and Terraform Enterprise, the root module for a workspace
|
||||
defaults to the top level of the configuration directory (supplied via version
|
||||
control repository or direct upload), but the workspace settings can specify a
|
||||
subdirectory to use instead.
