Ruby

The deplo.io build environment makes use of the Paketo Ruby buildpack.

Example App​

We have a basic Rails app in our examples repository. You can deploy it with nctl. This requires the rails command to be installed for the SECRET_KEY_BASE. If you don't have it, any long random string will do (127+ chars).

nctl create application rails \
  --git-url=https://github.com/ninech/deploio-examples \
  --git-sub-path=ruby/rails-basic \
  --env=SECRET_KEY_BASE=$(rails secret)

Build env considerations​

The build process offers a few env variables to adjus it to your use-case. See the how to section of the documentation for all available variables.

Override the Detected Ruby Version​

The buildpack will attempt to detect the desired ruby version from the Gemfile in the app source. It's possible to explicitly override the version using the build-env variable BP_MRI_VERSION.

--build-env=BP_MRI_VERSION="3.2.2"

Enabling Javascript at runtime​

If your Ruby application is making use of Javascript/ExecJS at runtime, you can enable it by setting the BP_INCLUDE_NODEJS_RUNTIME to "true".

This will enable NodeJS at runtime.

--build-env=BP_INCLUDE_NODEJS_RUNTIME="true"
