Overview

Wraps the terraform plan command which generates a speculative execution plan, showing what actions Terraform would take to apply the current configuration. This command will not actually perform the planned actions.

You can optionally save the plan to a file, which you can then pass to the Apply command to perform exactly the actions described in the plan.

For options accepted on construction, see Base#initialize.

When executing an instance of Plan via Base#execute, the following options are supported:

  • :directory: the path to a directory containing terraform configuration (deprecated in terraform 0.14, removed in terraform 0.15, use :chdir instead).

  • :chdir: the path of a working directory to switch to before executing the given subcommand.

  • :compact_warnings: when true, if terraform produces any warnings that are not accompanied by errors, they are shown in a more compact form that includes only the summary messages; defaults to false.

  • :destroy: when true, a plan will be generated to destroy all resources managed by the given configuration and state; defaults to false.

  • :detailed_exitcode: whether or not to return detailed exit codes when the command exits; this will change the meaning of exit codes to: 0 - Succeeded, diff is empty (no changes); 1 - Errored; 2 - Succeeded, there is a diff; defaults to false.

  • :input: when false, will not ask for input for variables not directly set; defaults to true.

  • :lock: when true, locks the state file when locking is supported; when false, does not lock the state file; defaults to true.

  • :lock_timeout: the duration to retry a state lock; defaults to “0s”.

  • :no_color: whether or not the output from the command should be in color; defaults to false.

  • :parallelism: the number of parallel resource operations; defaults to 10.

  • :plan: the path to output the plan if it should be saved to a file.

  • :refresh: when true, updates state prior to checking for differences; when false uses locally available state; defaults to true; this has no effect when :plan is provided.

  • :replace: force replacement of a particular resource instance using its resource address. If the plan would’ve normally produced an update or no-op action for this instance, Terraform will plan to replace it instead.

  • :replaces: an array of resource addresses to replace; if both replace and replaces are provided, all resources will be replaced.

  • :state: the path to the state file from which to read state and in which to store state (unless :state_out is specified); defaults to “terraform.tfstate”.

  • :target: the address of a resource to target; if both :target and :targets are provided, all targets will be passed to terraform.

  • :targets: an array of resource addresses to target; if both :target and :targets are provided, all targets will be passed to terraform.

  • :vars: a map of variables to be passed to the terraform configuration.

  • :var_file: the path to a terraform var file; if both :var_file and :var_files are provided, all var files will be passed to terraform.

  • :var_files: an array of paths to terraform var files; if both :var_file and :var_files are provided, all var files will be passed to terraform.

The Base#execute method accepts an optional second parameter which is a map of invocation options. Currently, the only supported option is :environment which is a map of environment variables to expose during invocation of the command.

Examples:

Basic Invocation

RubyTerraform::Commands::Plan.new.execute(
  directory: 'infra/networking',
  vars: {
    region: 'eu-central'
  })
