This version of GitHub Enterprise Server was discontinued on 2024-07-09. No patch releases will be made, even for critical security issues. For better performance, improved security, and new features, upgrade to the latest version of GitHub Enterprise Server. For help with the upgrade, contact GitHub Enterprise support.

Using conditions to control job execution

Prevent a job from running unless your conditions are met.

Note: GitHub-hosted runners are not currently supported on GitHub Enterprise Server. You can see more information about planned future support on the GitHub public roadmap.


Note: A job that is skipped will report its status as "Success". It will not prevent a pull request from merging, even if it is a required check.

You can use the jobs.<job_id>.if conditional to prevent a job from running unless a condition is met. You can use any supported context and expression to create a conditional. For more information on which contexts are supported in this key, see "Contexts."

Note: The jobs.<job_id>.if condition is evaluated before jobs.<job_id>.strategy.matrix is applied.

When you use expressions in an if conditional, you can, optionally, omit the ${{ }} expression syntax because GitHub Actions automatically evaluates the if conditional as an expression. However, this exception does not apply everywhere.

You must always use the ${{ }} expression syntax or escape with '', "", or () when the expression starts with !, since ! is reserved notation in YAML format. For example:

if: ${{ ! startsWith(github.ref, 'refs/tags/') }}

For more information, see "Expressions."

Example: Only run job for specific repository

This example uses if to control when the production-deploy job can run. It will only run if the repository is named octo-repo-prod and is within the octo-org organization. Otherwise, the job will be marked as skipped.

name: example-workflow
on: [push]
    if: github.repository == 'octo-org/octo-repo-prod'
    runs-on: ubuntu-latest
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
          node-version: '14'
      - run: npm install -g bats

On a skipped job, you should see "This check was skipped."

Note: In some parts of the workflow you cannot use environment variables. Instead you can use contexts to access the value of an environment variable. For more information, see "Variables."
