[quotengrote]

Is your feature request related to a problem?

I would like to use the healtchcheck functionality of docker containers, for that i would likt to check with curl if the application page is running.

Like that:

[...]
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:5000/"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 20s
[...]

Describe the solution you'd like
