Add new user to existing container

[cthiebault]

Is there a way to add new user to /etc/sftp-users.confonce the container already exists?
It seems that users are created only at first run:
https://github.com/atmoz/sftp/blob/master/entrypoint#L87-L121

We could imagine that users are created on each container start:

• if user does not exist, it creates & configure it
• if user already exists, it does nothing

In what scenario do you need to stop and start this container when you can simply recreate it (after updating sftp-users.conf)?

When using this image with Docker Compose : if I add users to my config, I need to manually destroy the container... I can't do just docker-compose up -d.
But you are right, I should be able to recreate this container without loosing anything!

In theory, you are right : Docker compose should recreates container when config changed (it does this for nginx for example).

I don't understand why docker compose does not recreate the container automatically when I add new users to sftp-users.conf.

Here is my docker-compose.yml:

version: '2'

services:

  sftp:    
    image: atmoz/sftp
    ports:
      - "2222:22"
    volumes:
      - ./sftp-users.conf:/etc/sftp-users.conf:ro
      - /srv/docker/sftp:/home

Using nginx image, docker compose recreates nginx container when I change config file... but it does not with sftp image :(

nginx:
  image: nginx
  volumes:
    - ./nginx/my-app.conf:/etc/nginx/conf.d/my-app.conf:ro    
    - ./nginx/htpasswd:/auth/htpasswd:ro

Any idea?

docker-compose up -d --force-recreate should recreate containers. Specify your sftp container name, to only recreate that.
