Running devcontainer up --workspace-folder . --config .devcontainer/flask/devcontainer.json works fine, it builds the image and stands up the docker compose service.
I want to utilize prebuilding with our docker compose stack so I take the resulting built images and push them to our repository. If anyone pulls those images and runs devcontainer up --workspace-folder . --config .devcontainer/flask/devcontainer.json it rebuilds the entire image from scratch
If in the devcontainers.json I use the image field then it doesn't rebuild but there's no good way to use something like VS Code's > Reopen in Container since it doesn't know it part of the docker compose stack.
Does devcontainers support using prebuilt images with docker compose files? Is there somethings special I need to do to get it to recognize the image is fully built or to point directly at the cache?
To me it seems like it seems to be running docker compose build instead of docker compose up when running devcontainers up. If I run docker compose up myself and then attach VS Code it seems to work as intended.

I recommend building the image with a separate configuration (this can be just a Dockerfile or a devcontainer.json) and then reference the resulting image in the docker-compose.yml without referencing a Dockerfile. This avoids relying on Docker's cache hits across machines and potentially architectures.
