community.general.terraform – Manages a Terraform deployment (and plans)

Note

This plugin is part of the community.general collection (version 3.8.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.general.

To use it in a playbook, specify: community.general.terraform.

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
backend_config
dictionary
A group of key-values to provide at init stage to the -backend-config parameter.
backend_config_files
list / elements=path
added in 0.2.0 of community.general
The path to a configuration file to provide at init state to the -backend-config parameter. This can accept a list of paths to multiple configuration files.
binary_path
path
The path of a terraform binary to use, relative to the 'service_path' unless you supply an absolute path.
check_destroy
boolean
added in 3.3.0 of community.general
    Choices:
  • no
  • yes
Apply only when no resources are destroyed. Note that this only prevents "destroy" actions, but not "destroy and re-create" actions. This option is ignored when state=absent.
force_init
boolean
    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.
init_reconfigure
boolean
added in 1.3.0 of community.general
    Choices:
  • no
  • yes
Forces backend reconfiguration during init.
lock
boolean
    Choices:
  • no
  • yes
Enable statefile locking, if you use a service that accepts locks (such as S3+DynamoDB) to store your statefile.
lock_timeout
integer
How long to maintain the lock on the statefile, if you use a service that accepts locks (such as S3+DynamoDB).
overwrite_init
boolean
added in 3.2.0 of community.general
    Choices:
  • no
  • yes
Run init even if .terraform/terraform.tfstate already exists in project_path.
parallelism
integer
added in 3.8.0 of community.general
Restrict concurrent operations when Terraform applies the plan.
plan_file
path
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.
plugin_paths
list / elements=path
added in 3.0.0 of community.general
List of paths containing Terraform plugin executable files.
Plugin executables can be downloaded from https://releases.hashicorp.com/.
When set, the plugin discovery and auto-download behavior of Terraform is disabled.
The directory structure in the plugin path can be tricky. The Terraform docs https://learn.hashicorp.com/tutorials/terraform/automate-terraform#pre-installed-plugins show a simple directory of files, but actually, the directory structure has to follow the same structure you would see if Terraform auto-downloaded the plugins. See the examples below for a tree output of an example plugin directory.
project_path
path / required
The path to the root of the Terraform directory with the vars.tf/main.tf/etc to use.
purge_workspace
boolean
    Choices:
  • no
  • yes
Only works with state = absent
If true, the workspace will be deleted after the "terraform destroy" action.
The 'default' workspace will not be deleted.
state
string
    Choices:
  • planned
  • present
  • absent
Goal state of given stage/project
state_file
path
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
list / elements=string
A list of specific resources to target in this plan/application. The resources selected here will also auto-include any dependencies.
variables
dictionary
A group of key-values to override template variables or those in variables files.
variables_files
list / elements=path
The path to a variables file for Terraform to fill into the TF configurations. This can accept a list of paths to multiple variables files.
Up until Ansible 2.9, this option was usable as variables_file.

aliases: variables_file
workspace
string
Default:
"default"
The terraform workspace to work with.

Notes

Note

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

Examples

- name: Basic deploy of a service
  community.general.terraform:
    project_path: '{{ project_dir }}'
    state: present

- name: Define the backend configuration at init
  community.general.terraform:
    project_path: 'project/'
    state: "{{ state }}"
    force_init: true
    backend_config:
      region: "eu-west-1"
      bucket: "some-bucket"
      key: "random.tfstate"

- name: Define the backend configuration with one or more files at init
  community.general.terraform:
    project_path: 'project/'
    state: "{{ state }}"
    force_init: true
    backend_config_files:
      - /path/to/backend_config_file_1
      - /path/to/backend_config_file_2

- name: Disable plugin discovery and auto-download by setting plugin_paths
  community.general.terraform:
    project_path: 'project/'
    state: "{{ state }}"
    force_init: true
    plugin_paths:
      - /path/to/plugins_dir_1
      - /path/to/plugins_dir_2

### Example directory structure for plugin_paths example
# $ tree /path/to/plugins_dir_1
# /path/to/plugins_dir_1/
# └── registry.terraform.io
#     └── hashicorp
#         └── vsphere
#             ├── 1.24.0
#             │   └── linux_amd64
#             │       └── terraform-provider-vsphere_v1.24.0_x4
#             └── 1.26.0
#                 └── linux_amd64
#                     └── terraform-provider-vsphere_v1.26.0_x4
