Health checks disable

[fate8383]

Hi, is there anyway I can disable container health checks? I know how to do that with master container it works but all other containers created by master container have health checks thus the logs building up my syslog. I could not figure it out how.

This is not possible, the only option would be to use manual-install.
We could only redirect the output of the healthcheck to /dev/null. What do you think @szaimen?

I wonder which container exactly is producing the logs? We are using nc for almost all healthcheck and that should not produce any logs, no?

healthcheck:
disable: true

Simple entry to docker compose for master container stops the health check and stops the logs, I just want to be able to do with child containers which master auto creates. Is it possible?

only if you use manual install

Ok understood, thanks

You could have a look at:

• systemd logs filled with mount unit entries if healtcheck is enabled docker/for-linux#679 (comment)
• systemd logs filled with mount unit entries if healtcheck is enabled docker/for-linux#679 (comment)
• systemd logs filled with mount unit entries if healtcheck is enabled docker/for-linux#679 in general

If those work, you can continue using the normal installation including its advantages

fantastic!
I created a new file /etc/rsyslog.d/01-blocklist.conf, containing:

if $msg contains "run-docker-runtime" and $msg contains ".mount: Succeeded." then {
stop
}

this worked, the other option in systemd with conf didn't work. Thanks a lot!
