Linux docker installation and use tutorial _docker

Docker is an open-source engine that can easily create a lightweight, portable, self-contained container for any application.

Developers compiling tests on notebooks can be deployed in bulk in a production environment, including VMS, bare metal, openstack clusters, and other basic application platforms.

Docker's source code is all written in the go language.

First, the basic environment

1, role, IP, version, kernel

ServerA 10.1.10.236 3.16.0-4-amd64 8.1 Docket
Docket 1.6.2

Second, install Docter

1. Add Source

echo "Deb Http://http.debian.net/debian jessie-backports main" >>/etc/apt/sources.list

2. Update source

Apt-get Update

3. Install Docker.io Package

Apt-get Install Docker.io

4. View version

Docker--version
Docker version 1.6.2, build 7C8FCA2

5, start the service

/etc/init.d/docker start
[OK] starting Docker (via Systemctl): Docker.service.

6. Pull Debian and CentOS mirrors

1) Pull the Debian mirror

Docker pull Debian
