tfupdate-action

About

Integrating tfupdate with Github Action to update

• Terraform
• Terraform Providers
• Terraform Modules

to the latest version with v0.12+ support (tfupdate originally supports it).

Behavior

When tfupdate-action is triggered, it checks the latest version of the resource you specified. If there is an update, it creates a pull request to bump a version against the base branch you specified.

If you want to skip the current latest version for some reason, you can simply close the pull request. tfupdate-action will not create another pull request for the same version.

Inputs

resource

Required The name of resource to be updated. Either "terraform" "provider" or "module".

recursive

Optional Whether to check a directory recursively or not. Default to "false".

ignore_path

Optional A regular expression for path to be ignored.

file_path

Optional A path to file or directory to be updated. Default to "./"

provider_name

Optional The name of provider. Required when setting "provider" resource.

provider_repo

Optional GitHub repository of provider. Required when using Verified/Community providers.

module_name

Optional The name of module. Required when setting "module" resource.

source_type

Optional The source type of module. Required when setting "module" resource. Either "github", "gitlab" or "tfregistryModule".

base_branch

Optional The branch name against which a PR will be created. Default to "master".

Optional A reviewer to be assigned to a PR. You can assign multiple reviewers with a comma-separated list (no spaces around the comma).
