RubyGems

Avrea caches gems from rubygems.org so that bundle install and gem fetch resolve dependencies from colocated cache on repeat runs.

On Avrea runners

Bundler is pre-configured with a mirror for rubygems.org:

bundle config --global mirror.https://rubygems.org https://avrea-host:8443/rubygems

Your workflow needs no changes:

workflow.yml

jobs:
  build:
    runs-on: avrea-ubuntu-latest
    steps:
      - uses: actions/checkout@v6
      - uses: ruby/setup-ruby@v1
        with:
          ruby-version: '3.3'
      - run: bundle install

Manual setup

Bundler

Configure Bundler to mirror rubygems.org through the cache:

bundle config --global mirror.https://rubygems.org https://avrea-host:8443/rubygems

Or per-project, set the source in your Gemfile:

Gemfile

source "https://avrea-host:8443/rubygems/"

gem "rails"

gem

Replace the default rubygems.org source:

gem sources --remove https://rubygems.org/
gem sources --add https://avrea-host:8443/rubygems/
gem sources --update
