PAPERLESS_BIND_ADDR not honored

[ottobaer]

Hi,

I'm using docker compose and it seems like the PAPERLESS_BIND_ADDR is not honored and it binds to :: by default.

Here is my docker-compose.env file

PAPERLESS_URL=https://paperless.lan.something.space
PAPERLESS_BIND_ADDR=127.0.0.1
PAPERLESS_PORT=8081
USERMAP_UID=1001
USERMAP_GID=1001
PAPERLESS_TIME_ZONE=Europe/Paris
PAPERLESS_SECRET_KEY=XXX 

The Webserver says it uses 127.0.0.1

webserver-1  | [2024-04-30 13:05:02 +0200] [251] [INFO] Starting gunicorn 21.2.0
webserver-1  | [2024-04-30 13:05:02 +0200] [251] [INFO] Listening at: http://127.0.0.1:8081 (251)
webserver-1  | [2024-04-30 13:05:02 +0200] [251] [INFO] Using worker: paperless.workers.ConfigurableWorker
webserver-1  | [2024-04-30 13:05:02 +0200] [251] [INFO] Server is ready. Spawning workers

But checking the ports shows otherwise

130 root@pandabaer /opt/paperless/paperless-ngx # ss -tulpn | grep docker
tcp   LISTEN 0      4096         0.0.0.0:8001       0.0.0.0:*    users:(("docker-proxy",pid=93403,fd=4))   
tcp   LISTEN 0      4096            [::]:8001          [::]:*    users:(("docker-proxy",pid=93413,fd=4))   

Some docker info

Docker Compose version 2.27.0
Docker       Version:           26.1.0

It works if I set it manually in the docker-compose.yml

 [..]
  webserver:
    image: ghcr.io/paperless-ngx/paperless-ngx:latest
    restart: unless-stopped
    depends_on:
      - db
      - broker
      - gotenberg
      - tika
    ports:
      - "127.0.0.1:8081:8000"
 [..]

Sockets

root@pandabaer pandabaer.lan.ursidae.space/opt/paperless/paperless-ngx # ss -tulpn | grep docker
tcp   LISTEN 0      4096       127.0.0.1:8081       0.0.0.0:*    users:(("docker-proxy",pid=96218,fd=4))   

I don't know if I'm doing something wrong here or if this is a bug.

That's not a bug. You seem confused by Docker networking vs paperless. Docker ports will always listen in all interface and that is not under the control of the container. The paperless bins address is being applied correctly, internal to the container.

Thanks for the help! I kinda got lost there for a moment. it seems. :-).
