The `checks` workflow deploys a Cloudflare Pages preview to the `pr-<number>` branch of the `docs-gitea-com` project for every pull request, but nothing ever removed it. Closed and merged pull requests therefore keep an alias and a growing list of deployments around. This adds a `cleanup preview` workflow that runs when a pull request is closed (merged or not), lists the deployments of the project through the Cloudflare API and deletes the ones whose trigger branch is `pr-<number>`. `force=true` is used so the deployment the branch alias points at is removed as well. Pull requests from forks do not receive the secrets, so the cleanup is skipped there, exactly like the preview deployment itself. --------- Co-authored-by: bircni <[email protected]> Reviewed-on: https://gitea.com/gitea/docs/pulls/517 Reviewed-by: bircni <[email protected]> Co-authored-by: Lunny Xiao <[email protected]>
