Resolved Can't install Docker

[Reboot]

As title says.

I can install the plugin, but I get this issue:

Warning: Local Docker nodes cannot be deployed in this environment. Only remote Docker nodes are available.

Any ideas why? This server is running CloudLinux by the way...

Here are the supported docker operating systems. Are you using Cloudlinux 7 ?

Yes, I do.

 

[danami]

If you are using Cloudlinux 7 then it should be supported. From the docs it says that it needs to be x64 and not using Virtuozzo ..

 

[Reboot]

So, can anyone from the Plesk team clarify this please?

 

[IgorG]

Could you please show me output of commands:

# plesk version
# mount

And make sure that you have installed Plesk not inside container. Docker can be used only on physical server or inside VM with hardware emulation (not container!)

Docker is supported in Plesk for the following operating systems: CentOS 7, RedHat 7, Debian 8, Ubuntu 14.04, Ubuntu 16.

As you can see, CloudLinux 7.x is not supported.

Unfortunate. Are you planning to support it?

 

[IgorG]

Docker can't be run on CloudLinux 7.2 even without Plesk. There is fatal error like level=fatal msg="Error starting daemon: Devices cgroup isn't mounted"

 

[Reboot]

Upon checking, CloudLinux support has clarified it:

Docker will not run on CloudLinux due to a different kernel design, and there are no plans to support it.

This FAQ: https://docs.plesk.com/en-US/17.0/faq/ needs to be update as it states centos 6 compatibility. Centos 6 is not supported.

Yes, you are correct - https://docs.plesk.com/en-US/17.0/a...esk-administration/using-docker.75823/#o77132 Thank you.
We will fix it soon.

Yes, you are correct - Using Docker Thank you.
We will fix it soon.

I'm using Plesk Onyx CentOS 6.10 and getting the same error as screenshot attached in #1.

Is there a fix to be applied so that Docker will work with CentOS 6?

Thanks

Yes, you are correct - Using Docker Thank you.

Any more news on this? I'm itching to get using docker on CentOS6.xxx

Thanks IgorG
