This tutorial shows the installation process of Docker on Linux.
Installing Docker on Linux
The simplest way to install Docker on Linux is by means of the installation script available on https://get.docker.com which contains some platforms checks to determine what Linux operating system you are running.
$ curl -sSL https://get.docker.com/ | sh
The alternative to curl is wget:
$ sudo wget -qO- https://get.docker.io/ | sh
Minimal requirements: Please note that the 3.10.x kernel is the minimum requirement for Docker. Besides this, Docker also requires that you are running a 64 bit machine.
Once installed you can check the Docker version by passing the version attribute to the docker command;
$ docker version Client: Version: 1.8.0 API version: 1.20 Go version: go1.4.2 Git commit: f5bae0a Built: Tue Jun 23 17:56:00 UTC 2015 OS/Arch: linux/amd64 Server: Version: 1.8.0 API version: 1.20 Go version: go1.4.2 Git commit: f5bae0a Built: Tue Jun 23 17:56:00 UTC 2015 OS/Arch: linux/amd64
