Healthcheck don't pass when minidlna tcp port is changed. about docker_base_images

[vladgh]

Please share the log output from the container.

Actually i tried reboot container and it is unhealty also without the warning above:

And failure count is increasing

[Hadatko]

I see that you are running healtcheck on different port than it is defined in minidlna enviroment variable.
curl --silent --fail 127.0.0.1:8200 || exit 1

IS this the reason for it?

[vladgh]

Yes, that must be it. But that's not something I can modify at build time, in the image. You must override the health check at runtime, in Portainer or docker-compose, or whatever you use.

[Hadatko]

You cannot set Healtcheck to something like this? Just thinking if we can solve it easily ;)

HEALTHCHECK --interval=10s --timeout=10s --retries=6 CMD \
  sh -c 'test -n "$MINIDLNA_PORT" || MINIDLNA_PORT=8200; \
  curl --silent --fail "http://127.0.0.1:$MINIDLNA_PORT" || exit 1'

[Hadatko]

I see this in image:

But this in container using newer image:

I will try changes locally and see

[vladgh]

It should work as expected:

[Hadatko]

Hi finally it is working. Not sure where was the issue, but minidlna is now using correct Healthcheck updated command (maybe i had to recreate minidlna, or do update on stack context and not container context...)

Tahnk you for helping and solving the issue ;)
