GitLab Pipeline trigger action

GitHub | GitHub Marketplace

This GitHub action triggers and waits for a GitLab pipeline to complete.

You can for example use this action in your GitHub workflow to trigger a deployment pipeline on a private GitLab server after a successful build pipeline and wait for the deployment (with possible End2End tests) to finish, so you would get a notification if the deployment failed.
