How to Set Up Odoo 18 Server Using Docker on Linux (Quick setup in 4 Steps)

Why Use Docker?

1. Bundling Dependencies: Docker enables the packaging of Odoo with all its required components and dependencies.

2. Isolation: Containerization provides isolation, preventing conflicts with other software installed on the system.

3. Industry Adoption: Considered as a crucial tool by developers.

4. Consistency: Docker facilitates consistent management across various environments.

5. Simplified Management: Docker streamlines the overall management of Odoo deployments.

Prerequisites

Before you can start setting up Odoo, ensure you have these essentials:

• A Linux distribution ( Ubuntu 22.04 is done in this setup)

• Docker and Docker Compose installed on your machine

• Basic knowledge of how to use terminal commands

  
  

Docker installation, simply run the following commands in your terminal:

sudo apt update

sudo apt install docker.io

sudo systemctl start docker

sudo systemctl enable docker 

To install Docker Compose:

sudo apt install docker-compose

Step 1: Create a Directory for Odoo

Next, create a directory to store all the essential files and configurations for Odoo. This keeps everything clean and manageable.

mkdir ~/odoo-docker

cd ~/odoo-docker

Step 2: Create a Docker Compose File

The `docker-compose.yml` file is crucial for your setup. It defines how the services will run. Create this file inside the `~/odoo-docker` directory.

Here’s a basic example of what this file should include:

in the docker-compose.yml file

Make adjustment to port and container name as shown below

version: '3.7'

services:

  odoo:

    image: odoo:18

    container_name: odoo-linux

    build: .  

    ports:

      - "8069:8069"  # Odoo web interface will be available on port 8069

    environment:

      - HOST=db 

      - USER=odoo 

      - PASSWORD=odoo 

      - DB_NAME=odoo  # Specify the database name

    volumes:

      - ./custom/addons:/mnt/extra-addons  # Mount your custom addons

      - odoo-data:/var/lib/odoo  # Persistent Odoo data

    depends_on:

      db:

        condition: service_healthy  # Wait for the database to be healthy

    networks:

      - odoo-net

    command: >  

      odoo --xmlrpc-port=8069  --init=base --load=base  --database=odoo

    healthcheck:

      test: ["CMD-SHELL", "curl -f http://localhost:8069 || exit 1"]

      interval: 30s

      timeout: 10s

      retries: 5

  db:

    image: postgres:15

    container_name: odoo-db-linux

    environment:

      - POSTGRES_DB=odoo

      - POSTGRES_USER=odoo

      - POSTGRES_PASSWORD=odoo

    volumes:

      - odoo-db-data:/var/lib/postgresql/data

    networks:

      - odoo-net

    healthcheck:

      test: ["CMD-SHELL", "pg_isready -U odoo"]

      interval: 30s

      timeout: 10s

      retries: 5

Explanation of the Compose File

• Web Service (odoo): This section runs the Odoo application, linking it to the database. It exposes port 8069, which is Odoo's default, allowing you to easily access the application.

• Database Service (db): This part sets up the PostgreSQL database that Odoo uses. I've specified essential environment variables for user, password, and database name. PostgreSQL is a reliable choice, with 65% of developers favoring it in database selections.

Step 3: Start the Containers

With your `docker-compose.yml` file ready, start your services with one command:

docker-compose up -d

The `-d` flag means that the containers will run in the background, allowing you to keep using your terminal.

Step 4: Access Odoo

After starting the services, open your web browser and navigate to `http://localhost:8069`. You should see the Odoo setup screen, ready for your next steps.

Stopping the Service

When your session is over or if you need to stop the services, simply execute:

docker-compose down 

This command will stop and remove the containers and network as defined in your `docker-compose.yml` file, cleaning up your environment.
