Unsupported functionality

While we try to implement all features of GitHub Runners, due to design choices and manpower available it's not possible to make act completely compatible.

Here is a list of features that is (yet) to be implemented or is decided as not going to be worked on by act maintainers.

Planned

  • concurrency is ignored
  • run-name is ignored
  • Step summary not processed
    • Values written in each step to the file pointed by GITHUB_STEP_SUMMARY, $GITHUB_STEP_SUMMARY and $env:GITHUB_STEP_SUMMARY are discarded, each step has its own empty step summary file at the beginning
  • Problem matcher ignored
  • Annotations ignored
  • Incomplete github context
  • Run steps cancellation not implemented
  • job.permissions ignored
  • job.timeout-minutes ignored
  • job.continue-on-error ignored
  • PATH of container / of act must contain node for nodejs actions, github runner has their own copy for both container and host
  • Openid Connect url is not defined
  • job.environment ignored and scoping secrets by deployment environment is not supported
