Install Docker In Debian 7 to virtualize A CentOS

Install Docker In Debian 7 to virtualize A CentOS

Currently, docker supports only Ubuntu 12.04 + and Debian 8.0 Jessie (64-bit) operating systems and does not support Debian 7 Wheezy. Before Running Docker, Linux kernel must be above 3.8, Go must be over 1.2, and Debian 7 must upgrade the kernel and compile the new version of Go to install. If OpenVZ VPS is used, the kernel cannot be upgraded. However, since Docker 0.8, it is no longer dependent on this. As long as the Linux kernel version is 2.6.32-431 or above.

PS: Docker 1.0 officially released! Version 1.0 contains many new features, which is also the first product version of Docker. From today on, You will always hear a new concept-Docker as a platform. Its components include the Docker engine, container runtime and packaging tools, and Docker Hub, this is a cloud-based collaboration, content and workflow Automation Service.

Confirm kernel version

Uname-r

Use the official ubuntu software source, which is compatible with debian 7:

Echo deb http://get.docker.io/ubuntu docker main | sudo tee/etc/apt/sources. list. d/docker. list
Sudo apt-key adv -- keyserver keyserver.ubuntu.com -- recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
Sudo apt-get update
Sudo apt-get install-y lxc-docker

Four-line command, Docker and installed. Create a CentOS virtual system as follows:

Docker pull centos
Docker run-I-t centos/bin/bash

Now we have entered the virtual CentOS system. Verify that:

Cat/etc/RedHat-release
