[Jane Jeon]

Would love this as well. Some form of built-in healthcheck would be nice.

[Viharm]

Yes, it would be good to have any form of healthcheck.

in the meantime you guys could do this (dockerfile_inline works in newer docker-compose versions):

version: '2.4'
services:
  whoami:
    container_name: whoami
    build:
      context: .
      dockerfile_inline: |
        FROM traefik/whoami
        COPY --from=ghcr.io/tarampampam/curl /bin/curl /curl
        HEALTHCHECK --interval=10s --start-period=2s CMD ["/curl", "--fail", "http://127.0.0.1:80/health"]
    restart: always
