Tini warnings on container start

ocgltd commented 11 months ago

What happened?

when I start the container the log reports:

Nov 23 04:22:50 lserver.mydomain.com zigbee2mqtt[3120474]: [WARN  tini (2)] Tini is not running as PID 1 and isn't registered as a child subreaper.
Nov 23 04:22:50 lserver.mydomain.com zigbee2mqtt[3120474]: Zombie processes will not be re-parented to Tini, so zombie reaping won't work.
Nov 23 04:22:50 lserver.mydomain.com zigbee2mqtt[3120474]: To fix the problem, use the -s option or set the environment variable TINI_SUBREAPER to register Tini as a child subreaper, or run Tini as PID 1.

What did you expect to happen?

I'm not sure what role Tini plays, but I don't expect this error. Also not sure what impact this is having.

How to reproduce it (minimal and precise)

I launched the container as follows:

docker run -d --init \
   -p 8090:8090 \
   -e TZ='America/Toronto' \
   -v /data/zigbee2mqtt/data:/app/data \
   -v /run/udev:/run/udev:ro \
   --name zigbee2mqtt \
   --device=/dev/ttyZigbee \
   docker.io/koenkk/zigbee2mqtt

In case it matters, I'm running on AlmaLinux 9 with podman (which offers command line compatibility with docker)

Zigbee2MQTT version

1.33.2

Adapter firmware version

Can't get that far

tini is a 'init' for containers https://github.com/krallin/tini It's invoked in your case because you use the --init option You can avoid the warning by adding -e TINI_SUBREAPER=
