Is there a way to execute terraform apply on a schedule using tfaction?

[5st7]

Question

Thank you for providing such a wonderful OSS.

I would like to execute terraform apply at a specific time using Cron to modify the resources based on the time of day or to correct drifts. I'm considering a setup where GitHub Actions creates a PR to modify the appropriate resources, automatically merges it, and then applies the changes. However, is there a better approach using tfaction?

Background of the question

background:

• modify resources only on holidays to reduce costs.
• reduce drift.

For these reasons, I’m considering executing terraform apply on a schedule.

tfaction doesn't provide a way to run terraform apply periodically.
It's potentially dangerous, so we have no plan to support it.

Probably you are aware, but tfaction supports the drift detection instead.

GitHub Actions creates a PR to modify the appropriate resources, automatically merges it, and then applies the changes.

I think this would work well.

If you don't want to create prs, you can implement the workflow based on apply.yaml or schedule-detect-drifts.yaml.
tfaction/terraform-apply isn't available because it requires a plan file in GitHub Artifacts, but you can still utilize other actions such as tfaction/setup.
