Docker-Cloud "own node" doesn't connect (ubuntu server)

I've tried to connect my vps Server with the dockercloud-agent, but I am not able to get it running.

I've tried multiple Ubuntu-Server versions (14.05, 15.05, and 16.xx) docker is installed, the cloud.docker script execuded.

On startup I get "deploying" on the docker-cloud Dasboard, but it always fails. This is the log output:

Reallocating containers in other nodes...
Reallocation done!

I've opened Ports:

TCP 6783
UDP 6783
TCP 2375

I've even tried to run it with disabled firewall.

what I've found out:

Solution

  • ok, I got it working on Ubuntu Server 16.04

    I first enabled the docker rest API:

    Now it should work.
