container undeterministically dies directly after startup

[derMart]

I have the problem, that the docker container sometimes! exits right after startup with exit code 0 showing only ftp-server_1 | process has died, quitting in the output but nothing else, no error message or anything. Restarting the container sometimes fixes the problem, very weird. Here is the configuration using docker-compose

ftp-server:
  environment:
    - USERS=user|pass|/home/user|${uid}
    - ADDRESS=localhost
  image: delfer/alpine-ftp-server
  ports:
    - '21:21/tcp'
    - '21000-21010:21000-21010/tcp'
  volumes:
    - './static_server/data:/home/user'

where ${uid} is an environment variable.

Seems like I'm experiencing something similar in #49 After more testing, it sometimes starts correctly, did not face any issues with Windows though

I can see there's a revert-22-master tag in docker hub, I tried it out and it seems like I don't get this error (at least after ~5 times). Although stopping the container is for some reason taking longer. Would you mind trying that tag @derMart ?

[derMart]

I tried the revert-22-master tag. As this is undeterministic it is hard to tell, but from now only 2 startups problem does not appear (EDIT: will report back when I got some more experience). But I also experience that the container is taking much longer to shutdown. Tbh, that is pretty annoying ...

@delfer But this might be a hint that there is a regression going on between revert-22-master and current release

@derMart @BenasB is this problem occurs with the latest image version? Whit Docker version do you use? Can you provide container output?

@delfer. I have the same problem. I'm using Docker Desktop 4.25.1 on a Mac with M1 chip. The latest version of the image. MacOS version is 14.1.1. Container output:

adduser: user 'user' in use
process has died, quitting

My docker compose file looks like this:

x-ftp-connection: &ftp-connection
  USERS: $CORE__CDN_FTP_USER|$CORE__CDN_FTP_PASSWORD|/home/local

services:
  storage:
    image: delfer/alpine-ftp-server
    environment: *ftp-connection
    volumes:
      - ./ftp_data:/home/local
    ports:
      - "21:21"
      - "21000-21010:21000-21010"

Same here. Container dies randomly during startup. Running Macbook Pro M3 and Docker Desktop 4.27.0.
