Ruby Release

To vendor ruby package into your release, run:

$ git clone https://github.com/cloudfoundry/bosh-package-ruby-release
$ cd ~/workspace/your-release
$ bosh vendor-package <RUBY-PACKAGE-VERSION> ~/workspace/bosh-package-ruby-release

Where RUBY-PACKAGE-VERSION is one of the provided ruby package names The above code will add a ruby package to your-release and introduce a spec.lock.

Adding a new Ruby version

Packages for new versions of Ruby can be added by modifying ci/versions.yml, then reconfiguring the CI pipeline by running ci/configure.sh.

The ci/versions.yml configuration requires that you know the following component versions that correspond with the Ruby version:

• The version of RubyGems
• The version of libyaml used by the Psych gem

New versions of RubyGems and libyaml must be added to the rubygems and libyamls top-level keys respsectively. Then, add the Ruby and component versions, as well as the stemcell to test against, as a new entry under the rubies key. An example config for Ruby 3.3:

- version: "3.3"
  rubygems: "3.5"
  libyaml: "0.2"
  stemcell: ubuntu-noble

NOTE: please ensure that any commands used in ci/templates/src/compile.env.erb are compatible with the newly added Ruby / RubyGems version.

Shared Concourse tasks

This repository provides a couple helpful Concourse tasks in ci/tasks/shared that can help keep the Ruby package vendored in your BOSH release up to date, and bump gem versions.

ci/tasks/shared/bump-ruby-package

The bump-ruby-package task runs bosh vendor-package to automatically update the version of Ruby vendored into your own BOSH release.

• GIT_USER_EMAIL: Required. The email that will be used to generate commits.
• GIT_USER_NAME: Required. The user name that will be used to generate commits.
• PACKAGE: Required. Specifies which package from ruby-release that will be vendored into your own BOSH release, e.g. the ruby-X.Y package.
• PACKAGE_PREFIX: Optional. Equivalent to passing --prefix to bosh vendor-package. For example, specifying a prefix of myrelease will vendor in the package as myrelease-ruby-X.Y instead of just ruby-X.Y.
• PRIVATE_YML: Required. The contents of config/private.yml for your own BOSH release. Necessary to run bosh vendor-package.
• RUBY_VERSION_PATH: Optional. Relative path within your release to the .ruby-version file. When specified, the .ruby-version file will be updated with the exact version number (including patch) for the Ruby package.

ci/tasks/shared/bump-gems

The bump-gems task runs bundle update on each of your Gemfiles and optionally vendors them into your repository.

• GEM_DIRS: Required. A space-separated list of directories that contain a Gemfile to run
• GIT_USER_EMAIL: Required. The email that will be used to generate commits.
• GIT_USER_NAME: Required. The user name that will be used to generate commits.
• PACKAGE: Required. The package you are using in your own BOSH release (e.g. ruby-X.Y). This ensures that the correct version of bundler will be used to make the updates, preventing issues where the version of bundler in your Gemfile.lock does not get out-of-sync with the version used.
• VENDOR: Optional. Boolean value that specifies you want to run bundle cache to vendor in the gems into your repository. Defaults to false.
• VENDOR_PATH: Optional. String value that specifies the BUNDLE_CACHE_PATH environment variable to use when vendoring gems. Default to vendor/package.

Compile and Runtime functions and scripts

Included functions in compile.env:

• bosh_bundle which runs bundle install ... targeted at ${BOSH_INSTALL_TARGET}
• bosh_bundle_local which runs bosh_bundle --local ... targeted at ${BOSH_INSTALL_TARGET}
• bosh_generate_runtime_env which generates ${BOSH_INSTALL_TARGET}/bosh/runtime.env

To use ruby-* package for compilation in your packaging script:

#!/bin/bash -eu
source /var/vcap/packages/<RUBY-PACKAGE-VERSION>/bosh/compile.env
...
bosh_bundle
bosh_generate_runtime_env

To use ruby-* package at runtime in your job scripts:

#!/bin/bash -eu
source /var/vcap/packages/<RUBY-PACKAGE-VERSION>/bosh/runtime.env
source /var/vcap/packages/your-package/bosh/runtime.env
bundle exec ...
