ubuntu12.04 安装docker

一、安装docker的前提条件

目前docker只支持64位CPU的架构（x86_64和AMD64）。不支持32位的CPU。运行linux3.8或者更高版本的内核，如版本过低建议进行内核的升级。
   
root@TS-V3RDS02:/home/david-dai# uname -a
Linux TS-V3RDS02 3.5.0-23-generic #35~precise1-Ubuntu SMP Fri Jan 25 17:13:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

升级内核：
   
sudo apt-get update
sudo apt-get install -y linux-image-generic-lts-trusty linux-headers-generic-lts-trusty
reboot
root@TS-V3RDS02:/home/david-dai# uname -a
Linux TS-V3RDS02 3.13.0-80-generic #124~precise1-Ubuntu SMP Tue Feb 23 18:05:11 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux


1、首先ubuntu上安装bridge包，才能允许docker使用桥接模式配置容器的IP

   
apt-get install -y bridge-utils
root@TS-V3RDS02:/home/david-dai# dpkg -l | grep bridge*
ii  bridge-utils                      1.5-2ubuntu7                 Utilities for configuring the Linux Ethernet bridge


2、修改网卡，使eth0为bridge模式

原网卡配置：

   
root@TS-V3RDS02:/home/david-dai# vim /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 172.22.64.31
        netmask 255.255.255.0

auto eth1
iface eth1 inet static
        address 221.228.208.184
        netmask 255.255.255.0
        gateway 221.228.208.49

up route add -net 172.22.0.0/16 gw 172.22.64.254


修改后网卡配置：

   
root@TS-V3RDS02:/home/david-dai# vim /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        #address 172.22.64.31
        #netmask 255.255.255.0
        #gateway 172.22.63.254
        # dns-* options are implemented by the resolvconf package, if installed

auto eth1
iface eth1 inet static
        address 221.228.208.184
        netmask 255.255.255.0
        gateway 221.228.208.49

auto zampbr0
iface zampbr0 inet static
address 172.22.64.31
netmask 255.255.255.0
bridge_ports eth0

up route add -net 172.22.0.0/16 gw 172.22.64.254

重启网卡：   
/etc/init.d/networking restart

查看网卡：

如果在安装的时候报错，请安装一些依赖包：

   
sudo  apt-get install apt-transport-https
sudo apt-get  install apparmor

root@TS-V3RDS02:/opt/dockerconfig# vim /etc/apt/sources.list.d/docker.list
#deb https://get.docker.io/ubuntu docker main
deb https://apt.dockerproject.org/repo ubuntu-precise main



/etc/init/docker.conf 记得加上这个参数 ,指定本地的私有仓库，拉去镜像很快，本地维护镜像。

重启docker

/etc/init.d/docker restart


安装pipwork

   
git clone https://github.com/jpetazzo/pipework
cp pipework/pipework /usr/bin/


创建docker容器

ping docker容器不通，原因是需要指定桥接网卡才可以，方法如下：



   
root@TS-V3RDS02:/opt/dockerconfig/scriprs# vi /etc/default/docker


DOCKER_OPTS="--dns 172.22.40.250 -b=zampbr0"


# Docker Upstart and SysVinit configuration file

#
# THIS FILE DOES NOT APPLY TO SYSTEMD
#
#   Please see the documentation for "systemd drop-ins":
#   https://docs.docker.com/engine/admin/systemd/
#

# Customize location of Docker binary (especially for development testing).
#DOCKERD="/usr/local/bin/dockerd"

# Use DOCKER_OPTS to modify the daemon startup options.
#DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"

# If you need Docker to use an HTTP proxy, it can also be specified here.
#export http_proxy="http://127.0.0.1:3128/"

# This is also a handy place to tweak where Docker's temporary files go.
#export DOCKER_TMPDIR="/mnt/bigdrive/docker-tmp"

然后重启docker，pipwork添加ip，即可ping通
   
/etc/init.d/docker restart
docker ps -a
docker start f9eb415a68a0
docker exec -it f9eb415a68a0  /bin/bash

二、安装docker

参考docker官方文档：

https://docs.docker.com/engine/installation/linux/ubuntu/


    Install packages to allow apt to use a repository over HTTPS:

    $ sudo apt-get install -y --no-install-recommends \
        apt-transport-https \
        ca-certificates \
        curl \
        software-properties-common

    Add Docker’s official GPG key:

    $ curl -fsSL https://apt.dockerproject.org/gpg | sudo apt-key add -

    Verify that the key ID is 58118E89F3A912897C070ADBF76221572C52609D.

    $ apt-key fingerprint 58118E89F3A912897C070ADBF76221572C52609D

      pub   4096R/2C52609D 2015-07-14
            Key fingerprint = 5811 8E89 F3A9 1289 7C07  0ADB F762 2157 2C52 609D
      uid                  Docker Release Tool (releasedocker) <docker@docker.com>

    Use the following command to set up the stable repository.

    实现如下功能：
    1
    2
        
    root@TS-V3RDS02:/opt/dockerconfig# vim /etc/apt/sources.list.d/docker.list
    deb https://apt.dockerproject.org/repo ubuntu-precise main


        Note: The lsb_release -cs sub-command below returns the name of your Ubuntu distribution, such asxenial.

    $ sudo add-apt-repository \
           "deb https://apt.dockerproject.org/repo/ \
           ubuntu-$(lsb_release -cs) \
           main"

    To enable the testing repository, you can edit /etc/apt/sources.list and add the word testing after mainon the appropriate line of the file. Do not use unstable repositories on production systems or for non-testing workloads.

        Note: Sometimes, in a distribution like Linux Mint, you might have to change ubuntu-$(lsb_release -cs) to your parent Ubuntu distribution. example: If you are using Linux Mint Rafaela, you could type inubuntu-trusty

Install Docker

    Update the apt package index.

    $ sudo apt-get update

    Install the latest version of Docker, or go to the next step to install a specific version. Any existing installation of Docker is replaced.

    Use this command to install the latest version of Docker:

    $ sudo apt-get -y install docker-engine

    可能需要增加：sudo apt-get -y install docker-engine --fix-missing

        Warning: If you have both stable and unstable repositories enabled, installing or updating without specifying a version in the apt-get install or apt-get update command will always install the highest possible version, which will almost certainly be an unstable one.

    On production systems, you should install a specific version of Docker instead of always using the latest. This output is truncated. List the available versions.

    $ apt-cache madison docker-enginedocker-engine | 1.13.0-0~ubuntu-xenial | https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages
    docker-engine | 1.12.6-0~ubuntu-xenial | https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages
    docker-engine | 1.12.5-0~ubuntu-xenial | https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages
    docker-engine | 1.12.4-0~ubuntu-xenial | https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages

    The contents of the list depend upon which repositories are enabled, and will be specific to your version of Ubuntu (indicated by the xenial suffix on the version, in this example). Choose a specific version to install. The second column is the version string. The third column is the repository name, which indicates which repository the package is from and by extension its stability level. To install a specific version, append the version string to the package name and separate them by an equals sign (=):

    $ sudo apt-get -y install docker-engine=<VERSION_STRING>

    The Docker daemon starts automatically.

    Verify that docker is installed correctly by running the hello-world image.

    $ sudo docker run hello-world

    This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.

Docker is installed and running. You need to use sudo to run Docker commands. Continue to Linux postinstall to allow non-privileged users to run Docker commands and for other optional configuration steps.
Upgrade Docker

To upgrade Docker, first run sudo apt-get update, then follow the installation instructions, choosing the new version you want to install.
Install from a package

If you cannot use Docker’s repository to install Docker, you can download the .deb file for your release and install it manually. You will need to download a new file each time you want to upgrade Docker.

    Go to https://apt.dockerproject.org/repo/pool/main/d/docker-engine/ and download the .deb file for the Docker version you want to install and for your version of Ubuntu.

        Note: To install a testing version, change the word main in the URL to testing. Do not use unstable versions of Docker in production or for non-testing workloads.

    Install Docker, changing the path below to the path where you downloaded the Docker package.

    $ sudo dpkg -i /path/to/package.deb

    The Docker daemon starts automatically.

    Verify that docker is installed correctly by running the hello-world image.

    $ sudo docker run hello-world

    This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.

Docker is installed and running. You need to use sudo to run Docker commands. Continue to Post-installation steps for Linux to allow non-privileged users to run Docker commands and for other optional configuration steps.
Upgrade Docker

To upgrade Docker, download the newer package file and repeat the installation procedure, pointing to the new file.
Uninstall Docker

    Uninstall the Docker package:

    $ sudo apt-get purge docker-engine

    Images, containers, volumes, or customized configuration files on your host are not automatically removed. To delete all images, containers, and volumes:

    $ sudo rm -rf /var/lib/docker

You must delete any edited configuration files manually.
