Customizing GitHub-hosted runners

You can install additional software on GitHub-hosted runners as a part of your workflow.

In this article

If you require additional software packages on GitHub-hosted runners, you can create a job that installs the packages as part of your workflow.

To see which packages are already installed by default, see "Using GitHub-hosted runners."

This guide demonstrates how to create a job that installs additional software on a GitHub-hosted runner.

Installing software on Ubuntu runners

The following example demonstrates how to install an apt package as part of a job.

name: Build on Ubuntu
on: push

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Check out repository code
        uses: actions/checkout@v4
      - name: Install jq tool
        run: |
          sudo apt-get update
          sudo apt-get install jq

Note

Always run sudo apt-get update before installing a package. In case the apt index is stale, this command fetches and re-indexes any available packages, which helps prevent package installation failures.

Installing software on macOS runners

The following example demonstrates how to install Brew packages and casks as part of a job.

name: Build on macOS
on: push

jobs:
  build:
    runs-on: macos-latest
    steps:
      - name: Check out repository code
        uses: actions/checkout@v4
      - name: Install GitHub CLI
        run: |
          brew update
          brew install gh
      - name: Install Microsoft Edge
        run: |
          brew update
          brew install --cask microsoft-edge

Installing software on Windows runners

The following example demonstrates how to use Chocolatey to install the GitHub CLI as part of a job.

name: Build on Windows
on: push
jobs:
  build:
    runs-on: windows-latest
    steps:
      - run: choco install gh
      - run: gh version
