terraform - Manages a Terraform deployment (and plans)

New in version 2.5.

Synopsis

  • Provides support for deploying resources with Terraform and pulling resource information back into Ansible.

Requirements

The below requirements are needed on the host that executes this module.

  • terraform

Parameters

Parameter Choices/Defaults Comments
binary_path
The path of a terraform binary to use, relative to the 'service_path' unless you supply an absolute path.
force_init
bool
    Choices:
  • no ←
  • yes
To avoid duplicating infra, if a state file can't be found this will force a `terraform init`. Generally, this should be turned off unless you intend to provision an entirely new Terraform deployment.
lock
Enable statefile locking, if you use a service that accepts locks (such as S3+DynamoDB) to store your statefile.
lock_timeout
How long to maintain the lock on the statefile, if you use a service that accepts locks (such as S3+DynamoDB).
plan_file
The path to an existing Terraform plan file to apply. If this is not specified, Ansible will build a new TF plan and execute it. Note that this option is required if 'state' has the 'planned' value.
project_path
required
The path to the root of the Terraform directory with the vars.tf/main.tf/etc to use.
state
    Choices:
  • planned
  • present ←
  • absent
Goal state of given stage/project
state_file
The path to an existing Terraform state file to use when building plan. If this is not specified, the default `terraform.tfstate` will be used.
This option is ignored when plan is specified.
targets
A list of specific resources to target in this plan/application. The resources selected here will also auto-include any dependencies.
variables
A group of key-values to override template variables or those in variables files.
variables_file
The path to a variables file for Terraform to fill into the TF configurations.

Notes

Note

  • To just run a terraform plan, use check mode.

Examples

# Basic deploy of a service
- terraform:
    project_path: '{{ project_dir }}'
    state: present
