Can't use Postgres Unix Sockets with Wallabag Docker container...

[dslovin]

Trying to setup wallabag with postgres database, using unix sockets instead of TCP. Seems like adding this to ansible's entry point should work:
database_socket: "{{ lookup('env', 'SYMFONYENVDATABASE_SOCKET')|default('~', true) }}"
but unfortunately it isn't.

I have a patch, but it didn't work (so no use in a PR)

Any insights in how to make this work?

Have you mounted the socket to the correct container?

I can not also connect to host's PostgreSQL socket. Maybe SYMFONY__ENV__DATABASE_SOCKET isn't supported as an environment variable?

My docker-compose.yml:

version: "3.8"

services:

  app:
    image: wallabag/wallabag
    ports:
      - "8081:80"
    environment:
      POSTGRES_PASSWORD: wallabag
      POSTGRES_USER: wallabag
      SYMFONY__ENV__DATABASE_DRIVER: pdo_pgsql
      SYMFONY__ENV__DATABASE_DRIVER_CLASS: Wallabag\CoreBundle\Doctrine\DBAL\Driver\CustomPostgreSQLDriver
      SYMFONY__ENV__DATABASE_SOCKET: /var/run/.s.PGSQL.5432
      SYMFONY__ENV__DATABASE_NAME: wallabag
      SYMFONY__ENV__DATABASE_USER: wallabag
      SYMFONY__ENV__DATABASE_PASSWORD: wallabag
    volumes:
      - type: bind
        source: /var/run/postgresql/.s.PGSQL.5432
        target: /var/run/.s.PGSQL.5432

I also can not get the docker container to respect the SYMFONY__ENV__DATABASE_SOCKET variable. It looks like the container tries to read the SYMFONY__ENV__DATABASE_PORT option which this documentation says it shouldn't (granted that is for the parameters.yml file and not the environment variables)

FAILED! => {"changed": false, "msg": "argument port is of type <class 'str'> and we were unable to convert to int: <class 'str'> cannot be converted to an int"}

Here is my docker-compose file:

    ports:
      - "8083:80"
    restart: unless-stopped

I have confirmed that this method of exposing the socket to an Ubuntu container running the psql command does work.

Hope this helps!

@kevinschachtschneider your setup fails because Ansible can't chown images to nobody:nobody on startup.

Try mounting it somewhere else, where it has permissions to chown.
(Using --user nobody doesn't work either, as then Ansible fails differently.)

A bind mount might work for you: - ./wallabag-images:/var/www/wallabag/web/assets/images

#256 might fix this.
