The terraform env delete command is used to create a delete state environment.
---
# Command: env delete
The `terraform env delete` command is used to delete an existing environment.
## Usage
Usage: `terraform env delete [NAME]`
This command will delete the specified environment.
To delete an environment, it must already exist, it must be empty, and
it must not be your current environment. If the environment
is not empty, Terraform will not allow you to delete it without the
`-force` flag.
If you delete a non-empty state (via force), then resources may become
"dangling". These are resources that Terraform no longer manages since
a state doesn't point to them, but still physically exist. This is sometimes
preferred: you want Terraform to stop managing resources. Most of the time,
however, this is not intended so Terraform protects you from doing this.
The command-line flags are all optional. The list of available flags are:
* `-force` - Delete the state even if non-empty. Defaults to false.
## Example
```
$ terraform env delete example
Deleted environment "example"!
```

The terraform workspace delete command is used to delete a workspace.
---
# Command: workspace delete
The `terraform workspace delete` command is used to delete an existing workspace.
## Usage
Usage: `terraform workspace delete [NAME]`
This command will delete the specified workspace.
To delete an workspace, it must already exist, it must have an empty state,
and it must not be your current workspace. If the workspace state is not empty,
Terraform will not allow you to delete it unless the `-force` flag is specified.
If you delete a workspace with a non-empty state (via `-force`), then resources
may become "dangling". These are resources that physically exist but that
Terraform can no longer manage. This is sometimes preferred: you want
Terraform to stop managing resources so they can be managed some other way.
Most of the time, however, this is not intended and so Terraform protects you
from getting into this situation.
The command-line flags are all optional. The only supported flag is:
* `-force` - Delete the workspace even if its state is not empty. Defaults to false.
## Example
```
$ terraform workspace delete example
Deleted workspace "example".

Environments are currently supported by the following backends:
* [Consul](/docs/backends/types/consul.html)
* [S3](/docs/backends/types/s3.html)
## Using Environments
Terraform starts with a single environment named "default". This
environment is special both because it is the default and also because
it cannot ever be deleted. If you've never explicitly used environments, then
you've only ever worked on the "default" environment.
Environments are managed with the `terraform env` set of commands. To
create a new environment and switch to it, you can use `terraform env new`,
to switch environments you can use `terraform env select`, etc.
For example, creating an environment:
```text
$ terraform env new bar
Created and switched to environment "bar"!
You're now on a new, empty environment. Environments isolate their state,
so if you run "terraform plan" Terraform will not see any existing state
for this configuration.
```
As the command says, if you run `terraform plan`, Terraform will not see
any existing resources that existed on the default (or any other) environment.
**These resources still physically exist,** but are managed by another
Terraform environment.
## Current Environment Interpolation
Within your Terraform configuration, you may reference the current environment
using the `${terraform.env}` interpolation variable. This can be used anywhere
interpolations are allowed.
Referencing the current environment is useful for changing behavior based
on the environment. For example, for non-default environments, it may be useful
to spin up smaller cluster sizes. You can do this:
```hcl
resource "aws_instance" "example" {
count = "${terraform.env == "default" ? 5 : 1}"
# ... other fields
}
```
Another popular use case is using the environment as part of naming or
tagging behavior:
```hcl
resource "aws_instance" "example" {
tags { Name = "web - ${terraform.env}" }
# ... other fields
}
```
## Best Practices
An environment can be used to manage the difference between development,
staging, and production, but it **should not** be treated as the only isolation
mechanism. As Terraform configurations get larger, it's much more
manageable and safer to split one large configuration into many
smaller ones linked together with `terraform_remote_state` data sources. This
allows teams to delegate ownership and reduce the blast radius of changes.
For **each smaller configuration**, you can use environments to model the
differences between development, staging, and production. However, if you have
one large Terraform configuration, it is riskier and not recommended to use
environments to model those differences.
The [terraform_remote_state](/docs/providers/terraform/d/remote_state.html)
resource accepts an `environment` name to target. Therefore, you can link
together multiple independently managed Terraform configurations with the same
environment easily. But, they can also have different environments.
While environments are available to all,
[Terraform Enterprise](https://www.hashicorp.com/products/terraform/)
provides an interface and API for managing sets of configurations linked
with `terraform_remote_state` and viewing them all as a single environment.
Environments alone are useful for isolating a set of resources to test
changes during development. For example, it is common to associate a
branch in a VCS with an environment so new features can be developed
without affecting the default environment.
Future Terraform versions and environment enhancements will enable
Terraform to track VCS branches with an environment to help verify only certain
branches can make changes to a Terraform environment.
## Environments Internals
Environments are technically equivalent to renaming your state file. They
aren't any more complex than that. Terraform wraps this simple notion with
a set of protections and support for remote state.
For local state, Terraform stores the state environments in a folder
`terraform.tfstate.d`. This folder should be committed to version control
(just like local-only `terraform.tfstate`).
For [remote state](/docs/state/remote.html), the environments are stored
directly in the configured [backend](/docs/backends). For example, if you
use [Consul](/docs/backends/types/consul.html), the environments are stored
by suffixing the state path with the environment name. To ensure that
environment names are stored correctly and safely in all backends, the name
must be valid to use in a URL path segment without escaping.
The important thing about environment internals is that environments are
meant to be a shared resource. They aren't a private, local-only notion
(unless you're using purely local state and not committing it).
The "current environment" name is stored only locally in the ignored
`.terraform` directory. This allows multiple team members to work on
different environments concurrently.

Workspaces allow the use of multiple states with a single configuration directory.

# Workspaces
A _workspace_ is a named container for Terraform state. With multiple
workspaces, a single directory of Terraform configuration can be used to
manage multiple distinct sets of infrastructure resources.
Terraform state determines what resources it manages based on what
exists in the state. This is how `terraform plan` determines what isn't
created, what needs to be updated, etc. The full details of state can be
found on [the _purpose_ page](/docs/state/purpose.html).
Multiple workspaces are currently supported by the following backends:
* [Consul](/docs/backends/types/consul.html)
* [S3](/docs/backends/types/s3.html)
In the 0.9 line of Terraform releases, this concept was known as "environment".
It was renamed in 0.10 based on feedback about confusion caused by the
overloading of the word "environment" both within Terraform itself and within
organizations that use Terraform.
## Using Workspaces
Terraform starts with a single workspace named "default". This
workspace is special both because it is the default and also because
it cannot ever be deleted. If you've never explicitly used workspaces, then
you've only ever worked on the "default" workspace.
Workspaces are managed with the `terraform workspace` set of commands. To
create a new workspace and switch to it, you can use `terraform workspace new`;
to switch environments you can use `terraform workspace select`; etc.
For example, creating a new workspace:
```text
$ terraform workspace new bar
Created and switched to workspace "bar"!
You're now on a new, empty workspace. Workspaces isolate their state,
so if you run "terraform plan" Terraform will not see any existing state
for this configuration.
```
As the command says, if you run `terraform plan`, Terraform will not see
any existing resources that existed on the default (or any other) workspace.
**These resources still physically exist,** but are managed in another
Terraform workspace.
## Current Workspace Interpolation
Within your Terraform configuration, you may include the name of the current
workspace using the `${terraform.workspace}` interpolation sequence. This can
be used anywhere interpolations are allowed.
Referencing the current workspace is useful for changing behavior based
on the workspace. For example, for non-default workspaces, it may be useful
to spin up smaller cluster sizes. For example:
```hcl
resource "aws_instance" "example" {
count = "${terraform.workspace == "default" ? 5 : 1}"
# ... other arguments
}
```
Another popular use case is using the workspace name as part of naming or
tagging behavior:
```hcl
resource "aws_instance" "example" {
tags {
Name = "web - ${terraform.workspace}"
}
# ... other arguments
}
```
## Best Practices

This allows teams to delegate ownership and reduce the potential impact of

[The `terraform_remote_state` data source](/docs/providers/terraform/d/remote_state.html)
accepts a `workspace` name to target. Therefore, you can link
together multiple independently managed Terraform configurations with the same
environment easily, with each configuration itself having multiple workspaces.
While workspaces are available to all,
[Terraform Enterprise](https://www.hashicorp.com/products/terraform/)
provides an interface and API for managing sets of configurations linked
with `terraform_remote_state` and viewing them all as a single environment.
Workspaces alone are useful for isolating a set of resources to test
changes during development. For example, it is common to associate a
branch in a VCS with a temporary workspace so new features can be developed
without affecting the default workspace.
Future Terraform versions and workspace enhancements will enable
Terraform to track VCS branches with a workspace to help verify only certain
branches can make changes to a Terraform workspace.
## Workspace Internals
Workspaces are technically equivalent to renaming your state file. They
aren't any more complex than that. Terraform wraps this simple notion with
a set of protections and support for remote state.
For local state, Terraform stores the workspace states in a directory called
`terraform.tfstate.d`. This directory should be be treated similarly to
local-only `terraform.tfstate`); some teams commit these files to version
control, although using a remote backend instead is recommended when there are
multiple collaborators.
For [remote state](/docs/state/remote.html), the workspaces are stored
directly in the configured [backend](/docs/backends). For example, if you
use [Consul](/docs/backends/types/consul.html), the workspaces are stored
by appending the environment name to the state path. To ensure that
workspace names are stored correctly and safely in all backends, the name
must be valid to use in a URL path segment without escaping.
The important thing about workspace internals is that workspaces are
meant to be a shared resource. They aren't a private, local-only notion
(unless you're using purely local state and not committing it).
The "current workspace" name is stored only locally in the ignored
`.terraform` directory. This allows multiple team members to work on
different workspaces concurrently.
