I do use compose for some things, smaller one off type setups, and I’ve done the compose up --build CI/CD approach before. I’m generally not a fan of building on the production node outside of very small deployments. It can work, I just think it tends to blur the line between build and runtime more than I’m comfortable with.

Some of my concerns with compose aren’t purely technical. It makes it easier to lean on local state like volumes, bind mounts, and large .env files. Similar mechanisms exist in kubernetes, but the additional setup tends to force a bit more thought about whether they’re actually needed or just a shortcut.

On the health check side, they exist, but compose doesn’t fully act on them, that's the part that is missing. There’s no built in remediation or orchestration behavior tied to health status, which is why things like https://github.com/willfarrell/docker-autoheal exist. It’s something that was never fully carried through in Docker itself.
