As I understand it, devcontainers use some base image and then instructions in json file with steps what to add for that specific app. Why not just make a docker image with everything your app needs and use it?
If you are using those, it gives you a nice push button way to get up and running. If you’re not using those, they’re pretty awkward — you just end up with images/containers that can only be built/run/interacted with using the devcontainer-cli tooling.
Would be nice if there was a simple standard way to point to a dockerfile in your repo (or even an image name) and say “build and run this for the dev env.” And the tools ecosystem could then reference and use standard container tools to build and run.

Genuine question. I want to use Docker for local dev loop but speed puts me off. I typically use it for "ready to push" tests.
