Ping endpoint working but docker healthcheck fails

hey,
please have a look on the recommended health check command. You can update the domain that points to Traefik instance and tune other parameters (internal, start_period) according to your needs.

 healthcheck:
      test: wget --quiet --tries=1 --spider http://ping.127.0.0.1.nip.io/ping || exit 1
      interval: 10s
      timeout: 1s
      retries: 3
      start_period: 10s
