|
The `terraform apply` command is used to apply the changes required
|
|
to reach the desired state of the configuration, or the pre-determined
|
|
set of actions generated by a `terraform plan` execution plan.
|
|
|
|
## Usage
|
|
|
|
Usage: `terraform apply [options] [plan]`
|
|
|
|
By default, `apply` scans the current directory for the configuration
|
|
and applies the changes appropriately. However, you can optionally give the
|
|
path to a saved plan file that was previously created with
|
|
[`terraform plan`](plan.html).
|
|
|
|
If you don't give a plan file on the command line, `terraform apply` will
|
|
create a new plan automatically and then prompt for approval to apply it. If the
|
|
created plan does not include any changes to resources or to root module
|
|
output values then `terraform apply` will exit immediately, without prompting.
|
|
|
|
The command-line flags are all optional. The list of available flags are:
|
|
|
|
* `-backup=path` - Path to the backup file. Defaults to `-state-out` with
|
|
the ".backup" extension. Disabled by setting to "-".
|
|
|
|
* `-compact-warnings` - If Terraform produces any warnings that are not
|
|
accompanied by errors, show them in a more compact form that includes only
|
|
the summary messages.
|
|
|
|
* `-lock=true` - Lock the state file when locking is supported.
|
|
|
|
* `-lock-timeout=0s` - Duration to retry a state lock.
|
|
|
|
* `-input=true` - Ask for input for variables if not directly set.
|
|
|
|
* `-auto-approve` - Skip interactive approval of plan before applying.
|
|
|
|
* `-no-color` - Disables output with coloring.
|
|
|
|
* `-parallelism=n` - Limit the number of concurrent operation as Terraform
|
|
[walks the graph](/docs/internals/graph.html#walking-the-graph). Defaults to
|
|
10.
|
|
|
|
* `-refresh=true` - Update the state for each resource prior to planning
|
|
and applying. This has no effect if a plan file is given directly to
|
|
apply.
|
|
|
|
* `-state=path` - Path to the state file. Defaults to "terraform.tfstate".
|
|
Ignored when [remote state](/docs/state/remote.html) is used. This setting
|
|
does not persist and other commands, such as init, may not be aware of the
|
|
alternate statefile. To configure an alternate statefile path which is
|
|
available to all terraform commands, use the [local backend](/docs/state/local.html).
|
|
|
|
* `-state-out=path` - Path to write updated state file. By default, the
|
|
`-state` path will be used. Ignored when
|
|
[remote state](/docs/state/remote.html) is used.
|
|
|
|
* `-target=resource` - A [Resource
|
|
Address](/docs/internals/resource-addressing.html) to target. For more
|
|
information, see
|
|
[the targeting docs from `terraform plan`](/docs/commands/plan.html#resource-targeting).
|
|
|
|
* `-var 'foo=bar'` - Set a variable in the Terraform configuration. This flag
|
|
can be set multiple times. Variable values are interpreted as
|
|
[HCL](/docs/configuration/syntax.html#HCL), so list and map values can be
|
|
specified via this flag.
|
|
|
|
* `-var-file=foo` - Set variables in the Terraform configuration from
|
|
a [variable file](/docs/configuration/variables.html#variable-files). If
|
|
a `terraform.tfvars` or any `.auto.tfvars` files are present in the current
|
|
directory, they will be automatically loaded. `terraform.tfvars` is loaded
|
|
first and the `.auto.tfvars` files after in alphabetical order. Any files
|
|
specified by `-var-file` override any values set automatically from files in
|
|
the working directory. This flag can be used multiple times.
|
|
|
|
## Passing a Different Configuration Directory
|
|
|
|
Terraform v0.13 and earlier also accepted a directory path in place of the
|
|
plan file argument to `terraform apply`, in which case Terraform would use
|
|
that directory as the root module instead of the current working directory.
|
|
|
|
That usage is still supported in Terraform v0.14, but is now deprecated and we
|
|
plan to remove it in Terraform v0.15. If your workflow relies on overriding
|
|
the root module directory, use
|
|
[the `-chdir` global option](./#switching-working-directory-with--chdir)
|
|
instead, which works across all commands and makes Terraform consistently look
|
|
in the given directory for all files it would normaly read or write in the
|
|
current working directory.
|
|
|
|
If your previous use of this legacy pattern was also relying on Terraform
|
|
writing the `.terraform` subdirectory into the current working directory even
|
|
though the root module directory was overridden, use
|
|
[the `TF_DATA_DIR` environment variable](environment-variables.html#TF_DATA_DIR)
|
|
to direct Terraform to write the `.terraform` directory to a location other
|
|
than the current working directory.
