How to upgrade the Ruby version

You can upgrade or downgrade your Ruby service to a different major Ruby version by setting the run.base parameter in your zerops.yaml. When you trigger a new pipeline, Zerops will start new runtime container(s) with the required Ruby version. If you don't specify the run.base attribute in your zerops.yaml, Zerops keeps the current Ruby version for your runtime.

If you want to build your application with a different major Ruby version, change the build.base parameter in your zerops.yaml. The build.base is the required attribute.
