Zabbix Web Container “Unlinking stale socket /tmp/supervisor.sock”

[Leaf-Oct]

Hello ～(∠·ω< )⌒★

I have some troubles when setting up zabbix server in Docker on Debian 13 (x64).

According to official document example 2, I ran a Postgre container as database, and ran zabbix-server-pgsql. Zabbix snmptraps is not needed so I didn't run it.

Finally, I ran zabbix-web-nginx-pgsql, but it didn't work healthily, printing "Unlinking stale socket /tmp/supervisor.sock" constantly.

The logs of zabbix-web-nginx-pgsql are following:

The Docker command I run are following (postgresql user and password are hidden):

docker run --name zabbix-postgre -t \
             -e POSTGRES_USER="***" \
             -e POSTGRES_PASSWORD="***" \
             -e POSTGRES_DB="***" \
             --restart unless-stopped \
             -v /home/zabbix-postgre-data:/var/lib/postgresql/data \
             -p 0.0.0.0:5432:5432 \
	     --network docker-net \
             -d postgres:17
docker run --name zabbix-server-pgsql -t \
             -e DB_SERVER_HOST="zabbix-postgre" \
             -e POSTGRES_USER="***" \
             -e POSTGRES_PASSWORD="***" \
             -e POSTGRES_DB="***" \
             --network docker-net \
             --restart unless-stopped \
             -d zabbix/zabbix-server-pgsql:7.4-ubuntu-latest
docker run --name zabbix-web -t \
             -e ZBX_SERVER_HOST="zabbix-server-pgsql" \
             -e DB_SERVER_HOST="zabbix-postgre" \
             -e POSTGRES_USER="***" \
             -e POSTGRES_PASSWORD="***" \
             -e POSTGRES_DB="***" \
             --network docker-net \
             -v /home/cert:/etc/ssl/nginx:ro \
             --restart unless-stopped \
	    -d zabbix/zabbix-web-nginx-pgsql:7.4-ubuntu-latest

These commands can make zabbix server working normally when I used Ubuntu 22. But it failed now on Debian 13. I have tried many tags of zabbix-server-pgsql and zabbix-web-nginx-pgsql, the result is same.

I have searched a lot in Bing and Google but get nothing useful. I would appriciate it if anyone can give me advice.

Hopefully thank~~~

Sorry, I can not reproduce the issue. Could you share "docker version" output?

@Leaf-Oct they have an incredibly over complex docker setup whereby they are including countless settings and configuration parameters from base files... you probably need to checkout this entire git repository locally.

then start with this psql file (since you are choosing ubuntu)
https://github.com/zabbix/zabbix-docker/blob/7.4/docker-compose_v3_ubuntu_pgsql_latest.yaml

and then trim/comment out all the services you don't want from it.
then use docker compose against the trimmed down file to start the stack.
