Cracking the Odoo 14 Docker Database Backup Error: Your Ultimate Solution Guide

Odoo Docker backup error solution – Have you ever encountered the frustrating database backup error while using Odoo 14 in a Docker environment? Don’t worry! We’ve got you covered. In this guide, we’ll walk you through the problem and provide a step-by-step solution to get your backups running smoothly again.

The Troublesome Error: What’s Going On?

First things first, let’s look at the error that’s causing all the trouble:

Error : Database backup error: Postgres subprocess ('/usr/bin/pg_dump', '--no-owner', '--file=/tmp/tmpagnpx8qa/dump.sql', 'dbname') error 1

This pesky error typically pops up when you’re trying to backup your database in Odoo 14 using Docker images. But fear not! Thanks to the helpful Odoo community, particularly Mr. Maizar Rahman from the Odoo – OpenERP Indonesia group, we’ve got a solution at hand.

The Root of the Problem: Digging Deeper

The issue stems from a glitch in the misc.py file. Fortunately, the open-source community has already identified and fixed this problem. You can find the source of the solution in this GitHub pull request.

The Quick Fix: Modifying misc.py

To resolve this error, we need to make a small change in the misc.py file. Here’s the code snippet you need to replace:

def exec_pg_command(name, *args):
    prog = find_pg_tool(name)
    env = exec_pg_environ()
    args2 = (prog,) + args
    rc = subprocess.call(args2, env=env, stdout=subprocess.DEVNULL, stderr=subprocess.STDOUT)
    if rc:
        raise Exception('Postgres subprocess %s error %s' % (args2, rc))

def exec_pg_command_pipe(name, *args):
    prog = find_pg_tool(name)

Two Ways to Implement the Fix

Now, let’s explore two methods to implement this solution:

Method 1: Fixing an Existing Odoo Container

If you’re already running an Odoo container, follow these steps:

1. Download the fixed misc.py file from this GitHub repository.
2. Copy the file into your container using this command:

   docker cp ./misc.py <container_name_or_id>:/usr/lib/python3/dist-packages/odoo/tools/misc.py

Remember to replace <container_name_or_id> with your actual container name or ID.

Method 2: Creating a New Docker Image

If you prefer to start fresh, you can create a new Docker image with the fix already implemented:

1. Use the Dockerfile from this GitHub repository.
2. Build your new image using the command:

   docker build -t odoo14-fixed:latest .

3. Run your new container using the freshly built image.

Wrapping Up: Your Odoo Backups, Solved!

By implementing either of these solutions, you should now be able to perform database backups in your Odoo 14 Docker environment without encountering the previous error. Remember, the open-source community is a treasure trove of solutions. Don’t hesitate to reach out and ask for help when you encounter issues!

We hope this guide has solved your Odoo backup woes. Happy developing, and may your databases always be safely backed up!
