Configure RubyGems Credentials for GitHub Actions

Configure your RubyGems credentials and for use in other GitHub Actions. This action implements OIDC support, writes gem credentials files, and exports environment variables used by both rubygems and bundler for your other Actions to use.

Table of Contents

Usage

We recommend that you use GitHub's OIDC provider in conjunction with a configured RubyGems OIDC API Key Role.

To do that, you would add the following step to your workflow:

- name: Configure RubyGems Credentials
  uses: rubygems/configure-rubygems-credentials@main
  with:
    role-to-assume: rg_oidc_akr_f55fe1127adjkkcn8ty6

You can use this action with the rubygems or bundler command line tools, or run this action multiple times to use different RubyGems.org accounts or OIDC API Key roles in the same GitHub Actions workflow. As an example, here is a complete workflow file that pushes a gem release.

on:
  - push

jobs:
  job:
    runs-on: ubuntu-latest
    permissions:
      contents: write
      id-token: write
    steps:
      - uses: rubygems/configure-rubygems-credentials@main
        with:
          role-to-assume: 2
          gem-server: 'https://oidc-api-token.rubygems.org'
          audience: 'https://oidc-api-token.rubygems.org'
      - uses: actions/checkout@v3
      - name: Set remote URL
        run: |
          git config --global user.email "$(git log -1 --pretty=format:'%ae')"
          git config --global user.name "$(git log -1 --pretty=format:'%an')"
          git remote set-url origin "https://x-access-token:${{ secrets.GITHUB_TOKEN }}@github.com/$GITHUB_REPOSITORY"
      - name: Set up Ruby
        uses: ruby/setup-ruby@v1
        with:
          ruby-version: '3.2.1'
          bundler-cache: true
      - name: Release
        run: bundle exec rake release

See action.yml for the full documentation for this action's inputs and outputs.

Examples

OIDC (recommended)

- name: Configure RubyGems Credentials
  uses: rubygems/configure-rubygems-credentials@main
  with:
    role-to-assume: 3

In this example, the Action will load the OIDC token from the GitHub-provided environment variable and use it to assume the role 3.

Static API token in repository secrets

- name: Configure RubyGems Credentials
  uses: rubygems/configure-rubygems-credentials@main
  with:
    api-token: ${{ secrets.RUBYGEMS_API_TOKEN }}

In this example, the secret RUBYGEMS_API_TOKEN contains a string like rubygems_1a072a969ecdd84bb190c3c218e13e3c6f5d419f3f0f5b22.

Use with the RubyGems CLI

This workflow does not install the rubygems into your environment.
