Easy installation of Docker with snap (1 command)

Install command

$ sudo snap install docker

only this.

By the way, docker-compose is also installed at the same time.

The following is a memorandum.

What is Snap?

Image: [https://snapcraft.io/about](https://snapcraft.io/about)

A software package that works with any Linux distribution. I have the impression that the number of apps distributed in this format has increased in recent years.

The tool required to use Snap is snapd, and if it is installed, you can use the snap command.

Personally, in addition to Docker, I am indebted to the installation of kubectl and Google Cloud SDK.

Recently, EKS Distro was announced and provided in a snap package. I hope it will be easier to build the Kubernetes environment from now on.

Install snapd

For Ubuntu

Ubuntu16,18,20 etc. are installed from the beginning, but if you need to install snapd based on Ubuntu, use the following command.

$ sudo apt update
$ sudo apt -y install snapd

For CentOS 7.6+


$ sudo yum install epel-release

Install snapd

$ sudo yum install snapd
$ sudo systemctl enable --now snapd.socket
$ sudo ln -s /var/lib/snapd/snap /snap

For Raspberry Pi

$ sudo apt update
$ sudo apt install snapd

Reboot once

$ sudo reboot
