Ubuntu – Cannot install docker on Ubuntu 17.10

dockerUbuntu

I have :
Ubuntu 17.10 – kernel 4.13.0-19-generic

No docker on the machine

Installing docker as https://github.com/docker/docker-install, ie :

curl -fsSL get.docker.com -o get-docker.sh
sh get-docker.sh

I get

$ docker -v
Docker version 17.11.0-ce, build 1caf76c

Nice, when I run $ sudo docked, I get

ERRO[2017-12-15T17:33:21.314578657+01:00] 'overlay' not found as a
supported filesystem on this host. Please ensure kernel is new enough
and has overlay support loaded.

ERRO[2017-12-15T17:33:21.316522224+01:00] 'overlay' not found as a
supported filesystem on this host. Please ensure kernel is new enough
and has overlay support loaded. Error starting daemon: error
initializing graphdriver: devicemapper:

Error running deviceCreate (CreatePool) dm_task_run failed

I try again, and get this time

driver devicemapper failed: devicemapper: Error running deviceCreate

Error starting daemon: error initializing graphdriver: devicemapper: Error running deviceCreate

What's wrong ?

I've installed a new VM with Ubuntu 17.10 in Virtualbox and I've updated the packages using apt.

Current kernel version:

$ uname -a
Linux test-VirtualBox 4.13.0-19-generic #22-Ubuntu SMP Mon Dec 4 11:58:07 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

I install Docker using your suggested script:

apt-get install curl -y
curl -fsSL get.docker.com -o get-docker.sh
sh get-docker.sh

I add my user account to the docker group:

sudo usermod -aG docker test

I log out and log in again so my group membership is updated.

I check the docker CLI version:

docker version

Docker 17.11 CE (edge) is installed.

I start the docker daemon and enable it:

$ sudo systemctl status docker
$ sudo systemctl enable docker

I check that the docker daemon is running well

$ sudo systemctl status docker

Docker daemon is using overlay2 as the storage driver. 

$ docker info
Containers: 0
 Running: 0
 Paused: 0
 Stopped: 0
Images: 0
Server Version: 17.11.0-ce
Storage Driver: overlay2
 Backing Filesystem: extfs
 Supports d_type: true
 Native Overlay Diff: true
Logging Driver: json-file
Cgroup Driver: cgroupfs

Overlay module is loaded:

lsmod | grep overlay
overlay                69632  0

I've rebooted the server and checked that docker has started fine and I can start a hello-world container:

$ docker run hello-world
...
Hello from Docker!

Everything looks good! So I suggest you to start your docker daemon using systemctl instead of starting it using dockerd from the shell.
