Docker: Error: "couldn't connect to host" - Code: 7

Blastmun · 8. Mai 2017

Hi,
Excuse me for my poor English.
I encounter a problem when I go into the Docker service after the first installation.

I tried to change the port unsuccessfully (56000 with rule on Firewall)...
I looked for a solution without success, so I come to you

Thank you

OMV 2.2.14
Linux 3.2.0-4-amd64
docker gui 0.2.23

Bash

Error: "couldn't connect to host" - Code: 7

Ah...I'm getting the same error was just about to post when I noticed your thread, I've left my defaults as is;

I would like to set this up for Emby, whilst the opensuse repo works if I have to stop the service to install an update then restart I keep getting errors so I thought I would try docker, never used is before but I have started to read the guide.

So... You have not found solution?

No one else has encountered this problem ?

I think most docker users are on OMV 3.x. So, not many running into this error to help.

Blastmun · 11. Mai 2017

but 3.X is'nt stable?

I've given up on the idea....I was having an minor issue with emby server, so I thought why not try Docker always willing to try and learn something else. But even google doesn't come up with anything Good idea while it lasted

Jetzt mitmachen!
