Correct install docker on omv 7

Maybe it's too hard for me after all.
omv 6 also took 2 months before I got it running.
Was happy then that it worked, and could have put a number of containers in it.
After the HDD crash I have to start over.
Fortunately, there were no important files on it.
I have watched so many different YouTube videos, and they are all explained in a different way.
The video of you is explained differently.
Why ??
I always start with a clean boot.
Format the HDD, then install Bookworm on the Android. This goes fast.
Then install Open Media Vault again.
And then install all settings correctly.
Always busy for several hours.

Started again.

Followed the instructions exactly as per the video.

I get this error message in the terminal

root@odroidxu4:~# sudo docker container stop portainer
Error response from daemon: No such container: portainer

No container available.

I get the message in openmedia vault

Pretty long.

I have looked at the OMV Quick Configuration Guide, but that will take me a few days to figure this out.

Another afternoon spent installing Docker.
Unfortunately no results.
SMB is visible but cannot open it.
I haven't gone any further to make a container.
If SMB does not work, there is no point in continuing with it.
Not all that easy I see.
Followed the instructions exactly. The only thing that may not have gone well is puid and pgid.
When I query this in terminal with id, I get puid 0
and pgid 0

root@odroidxu4:~# id
uid=0(root) gid=0(root) groups=0(root)

I don't feel like installing everything again.
Or quit because it just doesn't work for me.
