when nerdctl compose can support service health check

[mg1986jp]

Last I checked, nerdctl compose does support health checks — the healthcheck directive in compose files should work. What might be happening is that the health check is defined but not behaving the same as Docker Compose because nerdctl uses containerd's health check implementation under the hood.

Try something like:

services:
  web:
    image: nginx
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost/"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 10s

You can check the health status with:

nerdctl compose ps
nerdctl inspect <container-id> --format '{{ .State.Health }}'

If health checks aren't being picked up at all, check your nerdctl version — support was added in a relatively recent version. Also make sure you're running nerdctl compose and not accidentally using docker-compose with a nerdctl socket.

What specific health check behavior are you seeing vs expecting?
