.env ignored

I'm trying to run mattermost with podman-compose.

• https://github.com/mattermost/docker : podman-compose -f docker-compose.yml -f docker-compose.without-nginx.yml up

Nevertheless I get lots of errors:

[postgres]   | Error: Database is uninitialized and superuser password is not specified.
[postgres]   |        You must specify POSTGRES_PASSWORD to a non-empty value for the
[postgres]   |        superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".
[postgres]   | 
[postgres]   |        You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
[postgres]   |        connections without a password. This is *not* recommended.

• podman-compose 1.3.0, the latest version completely ignores the .env
  • empty POSTGRES_PASSWORD whereas it's actually set in .env
  • the permissions: Error: failed to load configuration: could not create config file: open /mattermost/config/config.json: permission denied

In docker-compose.yml, I've added :z and label:disable

    volumes:
      - ${MATTERMOST_CONFIG_PATH}:/mattermost/config:z

and

    security_opt:
      - no-new-privileges:true
      - label:disable

Any advice? Quite annoying in 2025 podman-compose is still incompatible with docker-compose...
