I just ran docker-compose up with your yaml and it worked fine for me.

Maybe insufficient resources allocated to Docker? I'm running Docker Desktop on Mac with resource allocation set to 8 vCPU, 20 GB memory and 2 GB swap.

I am experiencing the same issue.

[khirschmann-huebinet]

The problem could be solved by updating the docker version.

@khirschmann-huebinet Can you close this issue if you have a resolution?

Resolving Odoo 17 Thread Error in Docker
I encountered a RuntimeError: can't start new thread error while running Odoo 17 in a Docker container. After some troubleshooting, I found that the container needed additional privileges to access host machine resources. Here’s how I resolved the issue:

Use the --privileged Flag: Running the Docker container with the --privileged flag allows the container to access host resources directly, which can help resolve threading issues. You can modify your docker-compose.yml to include this flag :

services:
  web:
    ...
    privileged: true

It will work me
Note :

1. Use the --privileged flag only when absolutely necessary.
2. Consider using more granular capabilities with the --cap-add and --cap-drop options to limit the privileges instead of enabling all.
3. Regularly review and audit containers running with elevated privileges.
