I started learning docker recently and I set up a virtual machine (VirtualBox) with Lubuntu image:
- Linux verion:
Linux 4.18.0-10-generic i686
- Docker version:
1.38, Go version:
go1.10.4, Git commit:
So unless I have started acquaintance with swarm everything was going smoothly. However after I executed
docker swarm init daemon seemed going down and whatever command I’m now trying to execute, it responds with:
Cannot connect to Docker daemon at..
When I’m trying to run
sudo dockerd it shows the output where there’re some warnings like
failed to load plugin io.containerd.snapshotter.v1.btrfa and one error saying
error creating cluster object... error="name conflicts with an existing object" module=node node.id=... . Eventually the output ends with
floating point exception with some address in memory.
Restarting does not help. The only things that makes docker run is reverting to the snapshot that I luckily made before calling
swarm init .
So I would appreciate your help or advice how I do fix everything out.
