Zabbix

Monitoring Everything: Zabbix 6.0 in Docker Compose

by

Monitoring isn't optional. If you don't know your server is down before your users do, you've already failed.

Zabbix is the enterprise standard. It's powerful, it's free, and it's notoriously annoying to install manually. Dependencies, PHP versions, database schemas… it's a mess.

We are going to skip all that. We are going to deploy a full Zabbix 6.0 LTS stack in 30 seconds using Docker Compose.

The Stack

  • Zabbix Server: The brain.
  • Zabbix Web: The frontend (Nginx based).
  • PostgreSQL: The database (better performance than MySQL for Zabbix).
  • Zabbix Agent: To monitor the host itself.

The Configuration

Create docker-compose.yaml. Note the ZBX_ environment variables—this is how we configure the server without touching config files.

version: '3.5'
services:
  zabbix-server:
    image: zabbix/zabbix-server-pgsql:ubuntu-6.0-latest
    ports:
      - "10051:10051"
    volumes:
      - /etc/localtime:/etc/localtime:ro
    links:
      - postgres-server:postgresql
    restart: always
    environment:
      - POSTGRES_USER=zabbix
      - POSTGRES_PASSWORD=zabbix_password
      - POSTGRES_DB=zabbix

  zabbix-web-nginx-pgsql:
    image: zabbix/zabbix-web-nginx-pgsql:ubuntu-6.0-latest
    ports:
      - "8080:8080"
    volumes:
      - /etc/localtime:/etc/localtime:ro
    links:
      - zabbix-server:zabbix-server
      - postgres-server:postgresql
    restart: always
    environment:
      - ZBX_SERVER_HOST=zabbix-server
      - POSTGRES_USER=zabbix
      - POSTGRES_PASSWORD=zabbix_password
      - POSTGRES_DB=zabbix
      - PHP_TZ=Europe/Moscow

  postgres-server:
    image: postgres:13-alpine
    volumes:
      - ./zbx_env/var/lib/postgresql/data:/var/lib/postgresql/data
    environment:
      - POSTGRES_USER=zabbix
      - POSTGRES_PASSWORD=zabbix_password
      - POSTGRES_DB=zabbix
    restart: always

  zabbix-agent:
    image: zabbix/zabbix-agent:ubuntu-6.0-latest
    ports:
      - "10050:10050"
    volumes:
      - /etc/localtime:/etc/localtime:ro
    links:
      - zabbix-server:zabbix-server
    restart: always
    environment:
      - ZBX_HOSTNAME=Zabbix Server
      - ZBX_SERVER_HOST=zabbix-server

Deployment

  1. Run it: 
    docker-compose up -d
  2. Wait 30 seconds for the database to initialize.
  3. Go to http://localhost:8080.
  4. Login with Admin / zabbix.

Next Steps

You now have a monitoring server. Don't just stare at it. Add your first host, set up an email alert, and sleep better at night.
