How To: Install Docker in Ubuntu Using Snap

Docker Docker

One of the advantages snap package manager brings to Ubuntu is support for multiple versions of same software available and installable simultaneously. For example, you can decide if you want to run the stable or latest (edge) version of Docker.

Before You Install Docker with Snap

Apparently, snap model is not fully compatible with Docker right now, this means starting and using docker that you installed via snap is not as simple as you might expect.

Specifically, Docker is no longer maintaining the Docker version so it’s built and supported by Canonical (Ubuntu vendor).

The way I see it: if you just need a hassle free Docker setup, install Docker using apt-get from the official Docker repositories.

Confirm Docker Versions Available via Snap

Running snap info docker will list all the available channels for Docker in snap:

[email protected]:~ $ snap info docker
name: docker
summary: Docker container runtime

Build and run container images with Docker.

This build requires all files that Docker uses, such as dockerfiles, to be in $HOME. Keep files
there for 'docker build', 'docker save' and 'docker load'. Use the 'docker-privilege' command for
'docker run --privileged'.

Install Latest (Edge) Version of Docker with Snap

Based on the above, let’s install the latest Docker package version available via edge channel:

[email protected]:~ $ sudo snap install docker --edge
[sudo] password for greys:
Download snap "docker" (404) from channel "edge" 98% 316kB/s 9.50s
docker (edge) 18.09.7-ce from Canonical✓ installed

Check the Version of Docker We Just Installed

[email protected]:~ $ docker --version
Docker version 18.09.7-ce, build 3a74934
