Use [skip ci] in GitHub Actions

#github #actions
epassaro profile image epassaro ・Updated on ・1 min read

Actually GitHub Actions doesn't support skipping builds with [skip ci] like CircleCI, for example. But here's the magic trick:

jobs:
  build:
    runs-on: ubuntu-latest
    if: "! contains(toJSON(github.event.commits.*.message), '[skip ci]')"
Enter fullscreen mode Exit fullscreen mode

This snippet allows you to any custom filter you need! For example, I like to use:

jobs:
  build:
    runs-on: ubuntu-latest
    if: "contains(toJSON(github.event.commits.*.message), '[build]')"
Enter fullscreen mode Exit fullscreen mode

Only triggers the action if [build] is found in some pushed commit comment, like a manual trigger!

That's it.

Since I just had troubles using this, a quick reminder: the code above will check all commits in github.event.commits (which could be more than just the latest commit!) for [skip ci]. Therefore a workflow was skipped with a commit not having [skip ci] in the commit message, which was not intended...

If you want to just check the latest commit, change it to:

jobs:
  build:
    runs-on: ubuntu-latest
    if: "!contains(github.event.head_commit.message, '[ci skip]')"
Enter fullscreen mode Exit fullscreen mode
