Docker not running after updating to UCS 4.4-3

Hi,

on all systems the docker daemon wasn’t running after updating to UCS 4.4-3. Look like it was stopped during update but not started again after updating:

● docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
  Drop-In: /etc/systemd/system/docker.service.d

So I’ve started docker manually again:

systemctl start docker

Cheers,

Restarting the docker service is the correct workaround. The issue was that a check in our pre-update script was not removed from the previous update to UCS 4.4-2. We just pushed a fix to our update server.
