I'm trying to get a Ruby application running on Kubernetes, but I'm seeing an error about not being able to find libmysqlclient.so, I think because the "ruby" docker container doesn't have the libmysqlclient-dev package installed.
I'm trying to start the service with webservice --backend=kubernetes ruby2 start /data/project/verification-pages/verification-pages/script/toolforge-start. You can see the contents of the toolforge-start script here: https://github.com/mysociety/verification-pages/blob/d03f565b1f0bf0f03e07a125746c61e49a15b0d4/script/toolforge-start.
Here's a gist of the full error I'm getting: https://gist.github.com/chrismytton/fd1e254a393ebd36be0b5d9245138aab
I notice that the "python2" docker container does have this package - https://phabricator.wikimedia.org/diffusion/ODIT/browse/master/python2/base/Dockerfile.template;bac775da7cbeb7c275ae0a6251e9401524b6a2c0$18
so I _think_ that package needs to be added to the Ruby docker container here https://phabricator.wikimedia.org/diffusion/ODIT/browse/master/ruby/base/Dockerfile.template?
