Issue Docker-Extension not Installing

[manuth]

Hey Guys
I'm using Plesk Onyx on a Ubuntu 16.04:

Linux xxxxxxxx.net 4.4.0-042stab131.1 #1 SMP Wed Jun 20 16:32:07 MSK 2018 x86_64 x86_64 x86_64 GNU/Linux

When I try to install the Docker-Extension (1.3.1-126) I'm getting a strange error:

Die Installation der Erweiterung ist fehlgeschlagen.
Execution of /opt/psa/admin/plib/modules/docker/scripts/post-install.php failed with exit code 1 and the output:

Additionally the journalctl-log of docker says

Error starting daemon: Devices cgroup isn't mounted

Am I doing anything wrong?

Please check that it is your case Unable to install Docker inside a Virtuozzo 7 container: /dev/mapper/control: open failed: Operation not permitted

 

[manuth]

Hi IgorG
If I understand right this issue applies to me if I have my server hired from Virtuozzo which isn't the case for me.
I hav my server hired from Strato: Die Server von STRATO: Breite Auswahl für Ihre Projekte

Are there some further things I could do?
Thanks for the support

 

[IgorG]

But anyway, it is a virtual server, like Virtuozzo.

 

[manuth]

So in this case I should go contact the support of Strato, is that correct?
I'll post further information if the issue still consists.

Yes, try to ask their assistance. And pay your attention to Docker requirements and limitations Using Docker
