tfaction-root.yaml

`plan_workflow_name`

From tfaction v0.7.0, this setting is required.

plan_workflow_name: <GitHub Actions Workflow name running terraform-plan action>

e.g.

plan_workflow_name: test

`target` and `working_directory`

tfaction assumes that there are multiple working directories in the repository. Working directory is a directory where terraform commands such as terraform init, terraform plan, and terraform apply are run. tfaction treats directories where tfaction.yaml is located as working directories. Working directory has an attribute target, which is an identifier of the working directory. target must be unique. target is used in pull request comments and labels and the input of scaffold working directory. The attribute working_directory of the working directory is a relative file path to the working directory.

`target_groups`

target_groups is a list of target group configuration. tfaction searches the configuration of the working directory from target_groups. Target Group Configuration has attributes working_directory and target. If the Target Group's working_directory is the prefix of the working directory's working_directory, or the Target Group's target is the prefix of the working directory's target, the Target Group's configuration is used as the working directory's configuration and the search is stopped.

The order of target_groups is important.

target_groups:
- working_directory: aws/
  target: aws/
  # ...
- working_directory: aws/foo/ # This configuration is never used.
  target: aws/foo/
  # ...

Example

plan_workflow_name: test

draft_pr: true # default is false. If `draft_pr` is true, tfaction creates pull requests as draft
base_working_directory: "" # default is empty, which means the current directory
working_directory_file: tfaction.yaml # default is "tfaction.yaml"

# conftest_policy_directory: tfaction >= v1.1.0
# conftest_policy_directory is the file path to the conftest policy directory.
# The default value is "policy".
# If conftest_policy_directory isn't set and the directory policy doesn't exist, conftest is skipped.
# If conftest_policy_directory is set but the directory doesn't exist, the action fails.
