Command: plan
The terraform plan command is used to create an execution plan. Terraform
performs a refresh, unless explicitly disabled, and then determines what
actions are necessary to achieve the desired state specified in the
configuration files. The plan can be saved using -out, and then provided
to terraform apply to ensure only the pre-planned actions are executed.
Usage
Usage: terraform plan [options] [dir]
By default, plan requires no flags and looks in the current directory
for the configuration and state file to refresh.
The command-line flags are all optional. The list of available flags are:
-
-destroy- If set, generates a plan to destroy all the known resources. -
-detailed-exitcode- Return a detailed exit code when the command exits. When provided, this argument changes the exit codes and their meanings to provide more granular information about what the resulting plan contains:- 0 = Succeeded with empty diff (no changes)
- 1 = Error
- 2 = Succeeded with non-empty diff (changes present)
-
-input=true- Ask for input for variables if not directly set. -
-module-depth=n- Specifies the depth of modules to show in the output. This does not affect the plan itself, only the output shown. By default, this is -1, which will expand all. -
-no-color- Disables output with coloring. -
-out=path- The path to save the generated execution plan. This plan can then be used withterraform applyto be certain that only the changes shown in this plan are applied. Read the warning on saved plans below. -
-parallelism=n- Limit the number of concurrent operation as Terraform walks the graph. -
-refresh=true- Update the state prior to checking for differences. -
-state=path- Path to the state file. Defaults to "terraform.tfstate". -
-target=resource- A Resource Address to target. Operation will be limited to this resource and its dependencies. This flag can be used multiple times. -
-var 'foo=bar'- Set a variable in the Terraform configuration. This flag can be set multiple times. -
-var-file=foo- Set variables in the Terraform configuration from a file. If "terraform.tfvars" is present, it will be automatically loaded if this flag is not specified. This flag can be used multiple times.
Security Warning
Saved plan files (with the -out flag) encode the configuration,
state, diff, and variables. Variables are often used to store secrets.
Therefore, the plan file can potentially store secrets.
Terraform itself does not encrypt the plan file. It is highly recommended to encrypt the plan file if you intend to transfer it or keep it at rest for an extended period of time.
Future versions of Terraform will make plan files more secure.
