update: i tried downloading an image from: https://hub.docker.com/explore
and when i tried to do upload i got this error:

Internal error ;-P
<script></script><p>ERROR: Call to a member function getStatus() on string (IndexController.php:288)<br><br><a href='Help Center' target='_blank'>Search for related Knowledge Base articles</a></p>

another thing is: i cannot access the docker host settings again. when i first installed the extension i put in host my own server IP and in port i put 80.

thanks for your reply, i did what you asked, but when i am trying to set the docker i get this:

i already checked the /etc/hosts file and it says: 127.0.0.1 localhost

what do you suggest to put here

Hi Noam Harel,

plesk writes this: "No images are available in the catalog."

actually, this is no issue/error/problem, but a "not-very-well-designed" notice.
Just use a search - term like for example "plesk", to list available docker images from the catalog with the name "plesk".
At the moment, you have to define something and no "standart", "most installed", or what ever else someone could use as initial display option, is being displayed. This behaviour could be changed in future updates/upgrades for the Plesk docker Extension.

Thanks for your reply,

First of all, I would strongly recommend you to hide your IP address with the open port from public view. As you can imagine, consequences may be unpredictable...

Regarding your issue, I can assume that there is some kind of specific firewall rules on your server. Something does not let it out.
For example, I can reproduce your issue if I set following iptables rule:

iptables -A OUTPUT -p tcp -m string --string "docker" --algo kmp -j REJECT --reject-with tcp-reset

after that, if I run test command:

# docker run mssql

I see following errors in the output:

Unable to find image 'mssql:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: read tcp 10.52.44.14:53138->34.205.194.204:443: read: connection reset by peer.

You can try to find more details about this issue if you try to use similar command, like

# docker run hello-world

for example, and check the output.

thanks for your reply, i disabled plesk firewall & iptables:
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

also i tried running your commands, but server seems to not recognise them at all:
# docker run mssql
-bash: docker: command not found
# docker run hello-world
-bash: docker: command not found

it might be that i am missing something basic, or docker is not installed correctly...

forgot to mention: still i cannot see images or upload them.

Installing only the Plesk docker extension is absolutely not sufficent to run docker on your server, you need as well the "docker engine". Since you don't provide informations about YOUR current oparting system, I can only recommend to start reading:

=> Install Docker​
