podman with healthcheck fills journal with error

[HerrFrutti]

problem

My containers are healthy but my journal gets filled with error messages. The error seems to be related with healthchecks.

workaround

For now I disabled all healthchecks and the error disappeared.

logs

example line from my journal:

conmon[11328]: conmon 62de48d99d5858ab629f <error>: Unable to send container stderr message to parent Broken pipe

additional info

conmon version 2.1.7
podman version 4.6.1
podman-compose version 1.0.6
OS: Fedora release 37 (Thirty Seven)

I'm using podman-compose to deploy my containers.

Any known workarounds for this other than just disabling the health checks?

This is still a problem on Fedora 39

I have a couple of health checks and memory usage for journald is way beyond normal due to this. Until this bug gets fixed, I might have to disable my health checks, which is kind of sad :(

@mufeedali I am experiencing this issue too. How have you been disabling the health checks?

[mufeedali]

@benblasco by simply removing them from my podman-compose files

[shyzus]

@benblasco If you are dealing with images like the gitlab image which provides health checks by default. You can use this option to disable it --health-cmd=none

I've been noticing this problem on my OpenSUSE Leap 15.5 box. Containers are run through quadlet with podman 4.7.1.

I am also facing this problem with Ubuntu 22.04 LTS 64-bit. I am not using podman-compose.

raspberrypi@raspberrypi:~$ podman -v podman version 4.6.2

Thanks for sharing this info. I will have to figure out how to do this with quadlet!

Going through the documentation it appears as though the healthcmd directive can only be used for container units, and not pod units. Is there a way to override the healthcmd for a pod unit? Am I just reading the documentation incorrectly?

[rhatdan]

I don't think healthcmds effect Pods, they are a container concept. Pod's only have an infra container, which does not use healthcmds. Individual containers within the pod can have healthcmds.

I ended up adding the following to my .container file:

[Service]
# The following is for a conmon bug where it emits warnings for expected behavior.
LogFilterPatterns=~Broken pipe

See systemd.exec(1) for more information. YMMV if your container expects to have Broken pipe in its logging output during normal operation.

I'm having the same issue on debian unstable. Hoping for a fix soon!
