Error in `docker-compose.override.yml` when following the "Move Maildir" guide.

Repo

Hi everyone,

I followed the official guide to move my maildir to another location using the “old” approach. I also moved my existing maildir with the given commands. However, after creating the docker-compose.override.yml, mailcow is no longer starting. I get the following error if i run docker-compose up -d as given by the last step of the guide:

parsing /opt/mailcow-dockerized/docker-compose.override.yml: yaml: line 2: mapping values are not allowed in this context

The docker-compose.override.yml file I use looks like this:

version:·'2.1'
volumes:
  vmail-vol-1:
    driver_opts:
      type:·none
      device:·/mnt/path/to/dir/vmail
      o:·bind

I checked the file multiple times for indentation or space errors but couldn’t find any. Additionally, my file just contains the content given in the offical guide and except the different path I cannot find any differnce to the file’s content given there.

Has anyone of you already had a similar experience after moving their maildir or knows how I must change my docker-compose.override.yml file to make it run again? I hope, you can help me. Thanks in advance.

Behind the : at type, device, o and version. Why there stands · ?

version: '2.1'
volumes:
  vmail-vol-1:
    driver_opts:
      type: none
      device: /data/mailcow/vmail   
      o: bind

That’s what the documentation says. Try that.

Thanks a lot, I overlooked them as they are in other cases the whitespace indicator. But removing all of them, also the one behind “version” in the first line, solved my issue. So, thanks for the hint!
