Installation of Docker

There are installation guides in various environments on the official site, which mainly describes the installation of the Ubuntu and CentOS series.

Ubuntu Series installs Docker through the system comes with package installation

The Ubuntu 14.04 version number system has its own Docker package, which can be installed directly.

$sudoApt-get update$sudoApt-get install-y docker.io$sudoln-sf/usr/bin/docker.io/usr/local/bin/docker$sudoSed-i' $acomplete-F _docker Docker '/etc/bash_completion.d/docker.io

Assuming the operating system comes with a package to install Docker, the version number installed now is the older 0.9.1. The version number of the update to install. The ability to use the Docker source in a way.

Install the latest version number from the Docker source

To install the latest Docker version number, you first need to install APT-TRANSPORT-HTTPS support. It is then installed by adding a source.

$sudoApt-get Install apt-transport-https$sudoApt-key adv--keyserver hkp://keyserver.ubuntu.com: the--recv-keys $a1d7869245c8950f966e92d8576a8ba88d21e9$sudoBash-c"Echo Deb Https://get.docker.io/ubuntu Docker main >/etc/apt/sources.list.d/docker.list"$sudoApt-get update$sudoApt-get Install Lxc-docker

Version number before 14.04

If it is an Ubuntu system with a lower version number, you need to update the kernel first.

$sudoApt-get update$sudoApt-get Install linux-image-generic-lts-raring linux-headers-generic-lts-raring$sudoReboot

Then repeat the above steps to be able.

Start the Docker service after installation.

$ sudo service docker start
