Docker-Compose

To test the container we can use docker compose up -d (see initial setup):

version: "3.9"

services:
  database:
    image: mariadb:latest
    container_name: mautic-db
    environment:
      MYSQL_ROOT_PASSWORD: mypassword
    ports:
      - "3306:3306"
    volumes:
      - mautic-db:/var/lib/mysql:rw
    restart: always
    networks:
      - mauticnet
    command: --character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci --sql-mode=""

  mautic:
    container_name: mautic
    image: mautic/mautic:v4-apache
    volumes:
      - mautic-data:/var/www/html:rw
    environment:
      - MAUTIC_DB_HOST=database
      - MAUTIC_DB_USER=root
      - MAUTIC_DB_PASSWORD=mypassword
      - MAUTIC_DB_NAME=mautic4
      - MAUTIC_DB_TABLE_PREFIX=mautic4
    restart: always
    depends_on:
      - database
    links:
      - database
    networks:
      - mauticnet
    ports:
      - "8888:80"

networks:
  mauticnet:

Nomad Job

In Nomad we first need to create the volumes on our host in /etc/nomad.d/client.hcl and then define it here:

volume "mautic_db" {
    type      = "host"
    read_only = false
    source    = "mautic_db"
}

volume "mautic_data" {
    type      = "host"
    read_only = false
    source    = "mautic_data"
}

It can then be mounted into the container:

volume_mount {
    volume      = "mautic_db"
    destination = "/var/lib/mysql"
    read_only   = false
}

volume_mount {
    volume      = "mautic_data"
    destination = "/var/www/html"
    read_only   = false
}
