Question

You maintain a repository that contains three separate JavaScript actions, each in its own subdirectory (actions/linter/action.yml, actions/deployer/action.yml, actions/notifier/action.yml). Your team wants to publish the linter action to the GitHub Marketplace so external users can discover it. When you attempt to draft a release and check the 'Publish this Action to the GitHub Marketplace' option, the checkbox is unavailable. What is the most likely reason and correct remedy?

Accepted Answer

The Marketplace requires the action's action.yml (or action.yaml) metadata file to be in the repository root; move or extract the linter action into its own repository with the metadata file at the root.

Answer

The Marketplace only accepts Docker container actions; convert the linter action from JavaScript to a Dockerfile-based action before publishing.

Answer

You must add a marketplace.yml file listing all three actions in the repository root so GitHub knows which action to publish.

Answer

The repository visibility must be internal; change the repository from public to internal and the publish option will appear.
