Description

sample use case: I have a docker image that's built by CI, and is close enough to the code I want to run. I want to tilt up, have that image deployed, and then be able to live_update to it.

This is soooort of achievable at the moment by specifying a docker_build whose Dockerfile is just a one-line "FROM base-image", but that comes with the potentially major caveat that I have to pull that image to my laptop and then push it back up, which might be annoyingly expensive.

Research direction

Start by tracing the existing docker_build flow used by tilt up, focusing on where a base image is pulled and pushed before live_update. Identify the relevant image-sync entry points and tests, then define the behavior for using a CI-built image directly. Done means a prebuilt image can be deployed and live-updated without a local pull and registry push.
