Design m8s deployment workflows and tooling
Open, MediumPublic

Description

Now that we have jobs capable of building deployable images complete with multiple versions of MediaWiki, configuration, security patches, private settings, we need to deploy them to both k8s and legacy servers. Let's sketch out what that could look like from a deployer's perspective.

We (@dancy, @jeena, and @dduvall) brainstormed during our meeting today and came up with the following. It focuses on backport deployments. We also need to define commands/workflows for security patch updates, private settings updates, and train.

deployment commands

scap backport [--list]
scap backport change_url [change_url]
scap rollback
scap backport --revert change_url [change_url]

scap backport --revert change_id [change_id]

One quick point here, a change_id can refer to more than 1 change: https://gerrit.wikimedia.org/r/q/If04177f2a9f681002be5eafd97cbc5800aed2e27

I'm not sure if that's a problem or not, but something to be aware of in the design

I've changed the spec to take change_url as a parameter which could be either a change number or a full url (the contains the number), the important thing being that we should reference change numbers which are unique and not IDs which, as you mentioned, are not.
