Unclear doc: Uploading an extension to pootle

[boite]

I'm having difficulty understanding how to get files to be maintained by the pootle server. The README gives two options, the first being:-

In order to get the files there you can either add a SFTP container that has access to a specific repo folder e.g.

sftp:
  image: atmoz/sftp
  volumes:
    - /host/share:/home/foo/share
  ports:
    - "2222:22"
  command: foo:123:1001

---

I tried adding something like the example to docker-compose.yml:-

version: '2'

services: 
  ...
  sftp:
    image: atmoz/sftp
    volumes:
      - /path/to/my.repo:/srv/pootle/git-clones/repos/my.repo
    ports:
      - "2222:22"
    command: repowner:123:1001

volumes:
  mysql-data:
  l10n-ter:
  pootle-po:
  pootle-git:

but this doesn't get the files into pootle:-

$ docker-compose exec pootle bash -c "ls -al /srv/pootle/git-clones"
total 8
drwxr-xr-x 2 root root 4096 Aug 18 14:53 .
drwxr-xr-x 4 root root 4096 Aug 21 11:39 ..
$

What am I missing?

Regarding the docker-compose.yml if you would like to push a repo to your pootle instance via SFTP you would do e.g. this:

services:
pootle:
    image: 1drop/pootle:pootle
    volumes:
      - /path/to/my.repo:/srv/pootle/git-clones/my.repo
      - /path/to/another.repo:/srv/pootle/git-clones/another.repo
  sftp:
    image: atmoz/sftp
    command: foo:pass:1001
    volumes:
      - /path/to/my.repo:/home/foo/upload
  sftpanother:
    image: atmoz/sftp
    command: foo:pass:1001
    volumes:
      - /path/to/another.repo:/home/foo/upload

Thank you @hhoechtl that works. I'll make a PR to add this to the docs, but first a question: why does your example have pootle.image: 1drop/pootle:pootle? is this an example of extending docker-compose.yml (e.g. docker-composer.override.yml)?
