Using kunde21/gitea-arm:v1.13.1 on linux/arm/v7 getting Bind to port 22 on 0.0.0.0 failed: Address in use.

Running kunde21/gitea-arm:v1.13.1 in portainer (part of OMV 5 install) on raspberry pi 4b.

I am getting the following error in the container log:

Could not load host certificate "/data/ssh/ssh_host_ed25519_cert": No such file or directory
Could not load host certificate "/data/ssh/ssh_host_rsa_cert": No such file or directory
Could not load host certificate "/data/ssh/ssh_host_ecdsa_cert": No such file or directory

Bind to port 22 on :: failed: Address in use.
Bind to port 22 on 0.0.0.0 failed: Address in use.
Cannot bind any address.

i do see that openssh is running:

ash-5.0# ps aux

    1 root      0:00 /bin/s6-svscan /etc/s6

And port 22 is open and someone is listening:

ash-5.0# netstat -l

However when i look at docker ps I notice no ports being announced. May be a portainer thing.

The portainer UI does recognize the EXPOSEd ports correctly: 22 3000.

But I wanted to check with you first to make sure I am using your docker image correctly.

Note I am using a modified version of your docker-compose.yml.

Mine looks like this:

---
version: "2.1"
services:
  gitea:
    image: kunde21/gitea-arm:v1.13.1
    container_name: gitea
    network_mode: host
    environment:
      - USER_UID=1022
      - USER_GID=1022
    ports: 
      - "3000:3000"
      - "127.0.0.1:1022:22"
    volumes:
      - /srv/dev-disk-by-label-RAID1/gitea:/data
      - /home/git/.ssh/:/data/git/.ssh
    restart: unless-stopped

I did follow the instructions at SSH container passthrough.
However, this has no effect, of course, unless something is listening on the host port (1022 in my case).

Do you have any ideas? Am I missing something starting your image?

Thanks.

Forgot to mention I have tried both DISABLE_SSH = true and DISABLE_SSH = false in /data/gitea/conf/app.ini

The SSH_PORT = 22 and SSH_LISTEN_PORT = 22 have been kept at their default values.

The only edits i have made to this file are as follows to match my architecture.

[server]
...
DOMAIN           = pinas1
SSH_DOMAIN       = pinas1
HTTP_PORT        = 3000
ROOT_URL         = http://pinas1:3000/
...

I haven't attempted this setup, to be honest. The gitea forum or discord might be a better source of advice on it. I've done nothing to change the config or ssh server in this image, so I doubt it's specific to the image.

Having said that, the first thing that jumps out at me is you're attempting to bind to a low port while running as non-root (1022:1022) user. Try using a high port inside the container, in case that's the issue:
SSH_PORT = 2222 and

    ports: 
      - "3000:3000"
      - "127.0.0.1:1022:2222"
