hi @Gracious Joseph

i tried to follow as per your instructions as below, just made one change in your ~/odoo_docker/odoo16/docker-compose.yml file, I used image: postgres:16 instead of postgres:13:

odoo@odoo-VirtualBox:~$ pwd

/home/odoo

sudo apt install -y docker(dot)io docker-compose

sudo systemctl start docker

sudo systemctl enable docker

odoo@odoo-VirtualBox:~$ mkdir odoo-docker

odoo@odoo-VirtualBox:~$ cd odoo-docker

odoo@odoo-VirtualBox:~$ mkdir odoo15

odoo@odoo-VirtualBox:~$ mkdir odoo16

odoo@odoo-VirtualBox:~$ mkdir odoo17

odoo@odoo-VirtualBox:~$ cd ~/odoo-docker/odoo16

doo@odoo-VirtualBox:~/odoo-docker/odoo16$ sudo docker-compose up -d

[sudo] password for odoo:

ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

when running with: 

doo@odoo-VirtualBox:~/odoo-docker/odoo16$ sudo docker-compose up -d

odoo16-db is up-to-date

odoo16 is up-to-date

and trying to access in web browser http://localhost:8069 it is not showing odoo initial page instead below errors.

Unable to connect

Firefox can’t establish a connection to the server at localhost:8015.

here i stuck for the above and also for last folder postgres_data, can't change owner:group and permission, how i can test things will work fine or not.

please advise

with kind regards

Setting up Odoo with Docker for development on Ubuntu 22.04 is a practical approach, especially when working with multiple Odoo versions like 15, 16, and 17. Here’s a comprehensive guide tailored to your requirements:

1. Prerequisites

Before starting, ensure you have the following installed on your Ubuntu system:

• Docker and Docker Compose:

  bashCopy codesudo apt update
  sudo apt install -y docker.io docker-compose
  sudo systemctl start docker
  sudo systemctl enable docker
  

• Python 3.x (for development outside Docker if needed):

  bashCopy codesudo apt install python3 python3-pip
  

2. Set Up Directory Structure

Organize your project for multiple Odoo versions. For example:

javascriptCopy code~/odoo_docker/
├── odoo15/
├── odoo16/
└── odoo17/

Each version will have its Docker Compose file, configuration, and optional custom modules directory.

3. Create Docker Compose File

Create a docker-compose.yml file for each version in its respective folder.

Example for Odoo 16 (~/odoo_docker/odoo16/docker-compose.yml):

yamlCopy codeversion: '3.1'

services:
  db:
    image: postgres:13
    container_name: odoo16-db
    environment:
      - POSTGRES_USER=odoo
      - POSTGRES_PASSWORD=odoo
      - POSTGRES_DB=postgres
    volumes:
      - ./postgres_data:/var/lib/postgresql/data
    restart: always

  odoo:
    image: odoo:16
    container_name: odoo16
    depends_on:
      - db
    ports:
      - "8069:8069"
    environment:
      - HOST=db
      - USER=odoo
      - PASSWORD=odoo
    volumes:
      - ./odoo_addons:/mnt/extra-addons
      - ./odoo_data:/var/lib/odoo
    restart: always

4. Start Docker Containers

Navigate to the folder for the desired version and start the containers:

bashCopy codecd ~/odoo_docker/odoo16
docker-compose up -d

• The database will persist in the postgres_data volume.
• Additional custom modules can be added to the odoo_addons directory.

Repeat for other versions (15, 17) by creating separate configurations.

5. Configure Pycharm for Development

To use PyCharm for Odoo development:

1. Install PyCharm: Download and install PyCharm Professional or Community edition from JetBrains.
2. Configure PyCharm with Docker Interpreter:
   • Open PyCharm and go to Settings > Project > Python Interpreter.
   • Add a new interpreter and choose Docker.
   • Select the Odoo Docker container (e.g., odoo16) as the interpreter.
   • This allows PyCharm to use the Python environment inside the Docker container for development.
3. Set Up Project Folder:
   • Add the Odoo source code (if available) and the odoo_addons directory to your project in PyCharm.
   • Configure Odoo's addons path in the container to include mnt/extra-addons.

6. Development Workflow

• Modify or create custom modules in odoo_addons.
• Restart the Odoo container to apply changes:

  bashCopy codedocker-compose restart odoo
  

• Access Odoo at http://localhost:8069 for testing.

7. Managing Multiple Versions

Each version runs independently in its Docker container with its database. To avoid port conflicts:

• Change the exposed port for each version in the docker-compose.yml:

  yamlCopy codeports:
    - "8070:8069"  # For Odoo 15
    - "8071:8069"  # For Odoo 17
  

8. Best Practices

• Use Docker volumes to persist data and avoid losing work.
• Use the same PostgreSQL user/password for consistency across containers.
• If you need to test Python dependencies, install them directly in the container or on the host system.

9. Advanced Setup

• Enable Debugging in PyCharm:
  • Set breakpoints in your custom module.
  • Configure the Docker container to run in debug mode.
• Use VSCode as an Alternative:
  • Install the Remote - Containers extension for developing inside Docker.

Example Commands

• Stop a specific container:

  bashCopy codedocker-compose down
  

• View container logs:

  bashCopy codedocker logs odoo16
  

• Remove all containers and volumes:

  bashCopy codedocker-compose down -v
  

Summary

With this setup:

• Each Odoo version is isolated in its Docker container.
• Development can be done using PyCharm or other tools with Docker integration.
• PostgreSQL and custom modules are managed separately for each version.

Feel free to ask if you need further clarification or assistance with specific configurations!
