Odoo Bus.bus unavailable

I get regularly following error message while running odoo v14 locally in docker:

My odoo.conf file:

[options]

# Service Settings
addons_path = /home/odoo/addons/odoo/addons,/home/odoo/addons/extra,/home/odoo/custom/custom_addons,/home/odoo/custom/edited_addons,/home/odoo/custom/paysy_addons
data_dir = /var/lib/odoo

# Database
db_host = postgres-12.2
db_user = odoo_13_0_stage
db_password = password

# Tuning Options
workers = 2
max_cron_threads = 1
limit_time_cpu = 600
limit_time_real = 1200
osv_memory_age_limit = 1.0
osv_memory_count_limit = False

# Network / Ports
xmlrpc_port = 8069
netrpc_port = 8070
xmlrpcs_port = 8071
longpolling_port = 8072
proxy_mode = True

I think it hast something to do with longpolling but aren't sure. As you can see I already set the proxy_mode true, configured the longpolling port and set the 2 workers. I also tried to configure zero or more than two workers as suggested elsewhere.

Hopefully someone can help.

PS: Following my docker-compose file:

version: "3.9"
services:

    odoo-14.0-stage:
        container_name: odoo-14.0-stage
        image: odoo-14.0:stage

        ports:
            - 13001:8069/tcp
            - 8070:8070
            - 8071:8071
            - 8072:8072
        depends_on:
            - postgres-12.2
        volumes:
            - ./config:/etc/odoo:ro
            - ./volumes:/home/odoo/addons
            - ./addons:/home/odoo/custom
            - ./data:/var/lib/odoo
        restart: always

    postgres-12.2:
        container_name: postgres-12.2
        image: postgres:12.2
        build: ./postgres/12.2/
        volumes:
            - ./postgres/12.2/volumes/data:/var/lib/postgresql/data:delegated
        restart: always
Solution

  • Those logs are a cryptic way Odoo tells you that you need to configure your proxy correctly.

    Odoo normal operations are done through the main (also called HTTP) port, which defaults to 8069. However, long polling requests are a bit different:

    • In threaded mode (workers = 0, best for development), they pass though the same 8069 port.
    • In multiprocess mode (workers = 2 or more, best for production), they use a specific process which listens by default on port 8072.

    Your browser knows nothing about how Odoo is configured. It just makes all requests through the same port, whatever it is (tip: HTTP uses 80 by default, and HTTPS uses 443).

    That's why, if you are using Odoo in multiprocess mode, there must be an inverse proxy sitting between the web browser and Odoo, directing requests to the right port depending on the path.

    Odoo docs give an example nginx configuration and more details. Check them out: https://www.odoo.com/documentation/14.0/administration/install/deploy.html#id7
