The git operations/deployment-charts is the place we'll need to put stuff and where a new patchset would need to be made
Looks like the docs are still TBC but there is a ticket for writing them: https://phabricator.wikimedia.org/T213197 and in that ticket a link to https://wikitech.wikimedia.org/wiki/User:Alexandros_Kosiaris/Benchmarking_kubernetes_apps as some hint
This wikitech link also includes some steps we could take locally to validate both the helm file and optionally some basic performance benchmarking.
From IRC
<akosiaris> you can get the dockerfile the pipeline uses by talking to https://blubberoid.wikimedia.org/ <tarrow> one question I had when making the helm chart is: where is the name of the production image decided? e.g. I saw both wikimedia/blubber and wikimedia/mediawiki-services-citoid <akosiaris> it's the name of the repo in gerrit with the slashes turned dashes
