GitHub Action - Publish Gem to Rubygems

This is a GitHub Action written to streamline the Ruby gem publication process. The action sets the Gem Credentials from GITHUB_TOKEN and RUBYGEMS_API_KEYsecrets, and then runs rake release in your project root. You can override this command by setting RELEASE_COMMAND environment variable to the script that creates and publishes (this is usually only the case when a repository hosts multiple gems together).

Secrets Needed

GITHUB_TOKEN - Bundler needs this to create tags on your repo for the release RUBYGEMS_API_KEY - The Rubygems API Key for an Owner of the Gem you wish to publish. You can find your API Key by looking in ~/.gem/credentials or using the Rubygems API

Environment Variables

RELEASE_COMMAND - By default, this will invoke rake release to build and publish the gem to Rubygems. Set this environment variable if you have a custom release command to be invoked

Example

workflow "Publish Gem" {
  on = "push"
  resolves = ["Release Gem"]
}

action "Tag Filter" {
  uses = "actions/bin/filter@master"
  args = "tag v*"
}

action "Release Gem" {
  uses = "cadwallion/publish-rubygems-action@master"
  secrets = ["GITHUB_TOKEN", "RUBYGEMS_API_KEY"]
  needs = ["Tag Filter"]
}
