Use github.com and github enterprise simultaneously

[edwinrolle]

Hello fellow testers,

I have a workflow which consists of serval composite actions which reside in a github enterprise server.
Some of the composite actions make use of other 3rd party github actions, namely mikepenz/action-junit-report@v3

When I run my action with act -s GITHUB_TOKEN=<my-ghe-token> -P some-tag=catthehacker/ubuntu:act-22.04 --github-instance <my-ghe-server>

It fails because it tries to resolve the mentioned action mikepenz/action-junit-report@v3 on the ghe server but it is a public action.

Any recommendations how to resolve this?

act has a dedicated option for this mixed GHE + github.com case. Keep your Enterprise instance as the default, then redirect only the public action back to github.com:

act \
  --github-instance ghe.example.com \
  --replace-ghe-action-with-github-com=mikepenz/action-junit-report \
  -s GITHUB_TOKEN="$GHE_TOKEN"

For a private github.com action, or to avoid anonymous rate limits, also supply a separate dotcom token:

act \
  --github-instance ghe.example.com \
  --replace-ghe-action-with-github-com=mikepenz/action-junit-report \
  --replace-ghe-action-token-with-github-com="$GITHUB_DOTCOM_TOKEN" \
  -s GITHUB_TOKEN="$GHE_TOKEN"

Repeat --replace-ghe-action-with-github-com=owner/repo for each allowed public action. Match the action repository (mikepenz/action-junit-report), not a path inside it or the @v3 ref.

This is not just a URL workaround: current act first assigns remote actions to the configured GitHub Enterprise ServerURL, then checks the replacement list case-insensitively and switches matching repositories to https://github.com, optionally replacing the token. See step_action_remote.go and the CLI flags.

If the composite action references other public actions transitively, add each owner/repo to the replacement list as it appears in the failure log. If this resolves the mixed-host workflow, please mark the reply as accepted.
