Docker Build Ubuntu+mysql Environment tutorial

Docker is an open-source application container engine that allows developers to package their

Application and dependency packages into a portable container, and then publish to any popular

Virtualization can also be implemented on Linux machines. Containers are completely using the sandbox mechanism,

There will be no interfaces to each other.

Experiment Objective: using Docker in centos6.5 to get a preliminary understanding of the Docker creation process,

Create Ubuntu and MySQL images

and publish it and test it to experience how Docker works

One: to view the current Linux kernel version, Docker requires kernel 3. X

Uname-a View the kernel version if it is less than 3. x need to upgrade kernel

Kernel Upgrade Method:

1. Import Public key

RPM--import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

2, install Elrepo to the core of 2.6.32 CentOS

RPM-UVH http://www.elrepo.org/elrepo-release-6-8.el6.

elrepo.noarch.rpm

3. Install KERNEL-LT (long term support) version

Yum--enablerepo=elrepo-kernel Install Kernel-lt-y

4. Edit the grub.conf file and modify the Grub boot order

Vim/etc/grub.conf

Adjust the value of default to the order of the new kernel, such as the newly installed kernel in this upgrade case

Position is 0, so change default to 0, save exit

5. Check the kernel after rebooting the system

Two: Installing Docker

1 RPM-IVH http://dl.Fedoraproject.org/pub/epel/6/x86_64/epel-release-6

-8.noarch.rpm

2 rpm--import/etc/pki/rpm-gpg/rpm-gpg-key-epel-6

3 yum-y Install Device-mapper The docker process will die

4 yum-y Install Docker-io installing Docker

5 Service Docker start start Docker service

Three: Get a docker image

Docker pull Ubuntu

Docker pull MySQL

domestic public network get image image slow, available git get

git clone https://git.oschina.net/dockerf/

Docker-training.git//contains only common image

Four: Run test images

View images mirrored Docker images

Ubuntu Docker run-it Ubuntu/bin/bash
