Zabbix agent on docker container

[Gloukos]

Hello,

I'd like to monitor a basic docker container with nginx but when I start the zabbix_agentd, my nginx service stop, and I don't understand why ...
Can you help me or explain me the problem ?

When I don't start the agent in Dockerfile, i can start it without killing nginx, with docker exec

Here is my docker-compose :

version: "3.9"
  services:
    web:
      build:
        context: .
        dockerfile: Dockerfile
      restart: always
      container_name: webginx
      volumes:
        - /home/user/nginx/index.html:/var/www/html/index.html
        - /home/user/nginx/zabbix_agentd.conf:/etc/zabbix/zabbix_agentd.conf
      ports:
        - "8000:80"
        - "10051:10051"

And my Dockerfile:

# info version
FROM nginx:latest

#Full update
RUN apt update && apt upgrade -y

#Install package
RUN apt install -y procps\
&& apt install -y zabbix-agent

#config zabbix
CMD ["su", "zabbix", "-s", "/bin/bash", "-c", "/usr/sbin/zabbix_agentd -f"]
