Docker Zabbix for CoreOS server

This Docker container provides a patched Zabbix agent to monitor a real CoreOS server and all his containers.

The Zabbix agent has been patched to read system informations from these directories:

• /coreos/proc mapped from /proc on the real host
• /coreos/dev mapped from /dev on the real host
• /coreos/sys mapped from /sys on the real host

You can access the Docker REST API through the socket file /coreos/var/run/docker.sock

Usage

Build the image

# docker build -t bhuisgen/docker-zabbix-coreos .

Run the container

# docker run -d -p 10050:10050 \
    -v /proc:/coreos/proc -v /sys:/coreos/sys -v /dev:/coreos/dev \
    -v /var/run/docker.sock:/coreos/var/run/docker.sock
    --name zabbix-coreos bhuisgen/docker-zabbix-coreos <HOSTNAME> <SERVER_IP>

The needed arguments are:

• HOSTNAME: name of the host declared in the Zabbix frontend
• SERVER: IP address of the Zabbix server

Modify the agent configuration files

# docker exec -ti zabbix-coreos /bin/bash

Restarting the agent

# supervisorctl restart zabbix-agent
