For reference, here is internal Flatcar script which is used right now for building and publishing images to a community gallery: https://gist.github.com/invidian/41331399454b671f4f02ca693c731152. It also includes a staging gallery stage for testing.

EDIT: Also for reference here is the whole discussion about Flatcar images publishing: flatcar/Flatcar#734.

/milestone next

I've made great progress locally on prototyping this, but it's not going to come together in time for the v1.12 release this week.

I'm closing this for now to avoid distraction. It's backed up behind a couple other items:

• Remove go-dev container dependency
• Move all pipelines to Managed ID
• Maybe move pipelines from ADO to GH Actions
