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
LinuxTS-V3RDS023.5.0-23-generic#35~precise1-UbuntuSMPFriJan2517:13:26UTC2013x86_64x86_64x86_64GNU/Linux

升级内核：

sudoapt-getupdate
sudoapt-getinstall-ylinux-image-generic-lts-trustylinux-headers-generic-lts-trusty
reboot
root@TS-V3RDS02:/home/david-dai#uname-a
LinuxTS-V3RDS023.13.0-80-generic#124~precise1-UbuntuSMPTueFeb2318:05:11UTC2016x86_64x86_64x86_64GNU/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-getinstall-ybridge-utils
root@TS-V3RDS02:/home/david-dai#dpkg-l|grepbridge*
iibridge-utils1.5-2ubuntu7UtilitiesforconfiguringtheLinuxEthernetbridge


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

#Thisfiledescribesthenetworkinterfacesavailableonyoursystem
#andhowtoactivatethem.Formoreinformation,seeinterfaces(5).

#Theloopbacknetworkinterface

uprouteadd-net172.22.0.0/16gw172.22.64.254


修改后网卡配置：

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

#Thisfiledescribesthenetworkinterfacesavailableonyoursystem
#andhowtoactivatethem.Formoreinformation,seeinterfaces(5).

重启网卡：

/etc/init.d/networkingrestart

如果在安装的时候报错，请安装一些依赖包：

sudoapt-getinstallapt-transport-https
sudoapt-getinstallapparmor

root@TS-V3RDS02:/opt/dockerconfig#vim/etc/apt/sources.list.d/docker.list
#debhttps://get.docker.io/ubuntudockermain
debhttps://apt.dockerproject.org/repoubuntu-precisemain



/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

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="--dns172.22.40.250-b=zampbr0"


#DockerUpstartandSysVinitconfigurationfile

#UseDOCKER_OPTStomodifythedaemonstartupoptions.

#ThisisalsoahandyplacetotweakwhereDocker'stemporaryfilesgo.
#exportDOCKER_TMPDIR="/mnt/bigdrive/docker-tmp"

然后重启docker，pipwork添加ip，即可ping通

二、安装docker

参考docker官方文档：

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


  1. Install packages to allowaptto use a repository over HTTPS:

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

  2. Add Docker’s official GPG key:

    $curl-fsSLhttps://apt.dockerproject.org/gpg|sudoapt-keyadd-

    Verify that the key ID is58118E89F3A912897C070ADBF76221572C52609D.

    $apt-keyfingerprint58118E89F3A912897C070ADBF76221572C52609D

pub4096R/2C52609D2015-07-14
Keyfingerprint=58118E89F3A912897C070ADBF76221572C52609D
uidDockerReleaseTool(releasedocker)<docker@docker.com>

  3. Use the following command to set up thestablerepository.

    实现如下功能：

  4. root@TS-V3RDS02:/opt/dockerconfig#vim/etc/apt/sources.list.d/docker.list
debhttps://apt.dockerproject.org/repoubuntu-precisemain


  5. Note: Thelsb_release -cssub-command below returns the name of your Ubuntu distribution,such asxenial.

    $sudoadd-apt-repository\
"debhttps://apt.dockerproject.org/repo/\
ubuntu-$(lsb_release-cs)\
main"

    To enable thetestingrepository,you can edit/etc/apt/sources.listand add the wordtestingaftermainon 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 changeubuntu-$(lsb_release -cs)to your parent Ubuntu distribution. example: If you are usingLinux Mint Rafaela,you could type inubuntu-trusty

Install Docker

  1. Update theaptpackage index.

    $sudoapt-getupdate

  2. 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:

    $sudoapt-get-yinstalldocker-engine
  3. 可能需要增加：sudoapt-get-yinstalldocker-engine--fix-missing

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

  4. 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-cachemadisondocker-enginedocker-engine|1.13.0-0~ubuntu-xenial|https://apt.dockerproject.org/repoubuntu-xenial/mainamd64Packages
docker-engine|1.12.6-0~ubuntu-xenial|https://apt.dockerproject.org/repoubuntu-xenial/mainamd64Packages
docker-engine|1.12.5-0~ubuntu-xenial|https://apt.dockerproject.org/repoubuntu-xenial/mainamd64Packages
docker-engine|1.12.4-0~ubuntu-xenial|https://apt.dockerproject.org/repoubuntu-xenial/mainamd64Packages

    The contents of the list depend upon which repositories are enabled,and will be specific to your version of Ubuntu (indicated by thexenialsuffix 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 (=):

  1. $sudoapt-get-yinstalldocker-engine=<VERSION_STRING>

    The Docker daemon starts automatically.

  2. Verify thatdockeris installed correctly by running thehello-worldimage.

    $sudodockerrunhello-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 usesudoto run Docker commands. Continue toLinux postinstallto allow non-privileged users to run Docker commands and for other optional configuration steps.

Upgrade Docker

To upgrade Docker,first runsudo apt-get update,then follow theinstallation 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.debfile for your release and install it manually. You will need to download a new file each time you want to upgrade Docker.

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

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

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

    $sudodpkg-i/path/to/package.deb

    The Docker daemon starts automatically.

  3. Verify thatPost-installation steps for Linuxto allow non-privileged users to run Docker commands and for other optional configuration steps.

    Uninstall Docker

    1. Uninstall the Docker package:

      $sudoapt-getpurgedocker-engine

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

      $sudorm-rf/var/lib/docker

    You must delete any edited configuration files manually.
