Centos 6.x 升级docker 1.7.1 至 docker 1.13.0

前言

  随着docker的不断升级，也提供更加丰富的功能，目前Centos6.x默认最新版本仅为 Docker version 1.7.1, build 786b29d/1.7.1

  该版本对于docker的监控功能少之极少，为了方便通过zabbix监控docker服务的性能，以下将docker升级至 1.13.0版本

环境

操作系统 ： centos 6.7

docker版本：Docker version 1.7.1, build 786b29d/1.7.1

docker升级目前版本：Docker version 1.13.0

相关依赖环境：yum install udev udev-devel device-mapper-libs

操作

一、卸载docker服务，卸载之前请将容器及数据进行备份

  #> rpm -qa | grep docker

docker-io-1.7.1-2.el6.x86_64

 #> rpm -e docker-io-1.7.1-2.el6.x86_64

二、上传新版docker文件

 文件下载地址：https://download.docker.com/linux/static/stable/x86_64/ 

 将文件上传服务器进行解压 

 以下官方安装说明

1、Download the static binary archive. Go to https://download.docker.com/linux/static/stable/ (or change stable to nightly or test), choose your hardware platform, and download the .tgz file relating to the version of Docker Engine - Community you want to install.

2、Extract the archive using the tar utility. The dockerd and docker binaries are extracted.

	$ tar xvf /path/to/docker-1.13.0.tgz
3、Optional: Move the binaries to a directory on your executable path, such as /usr/bin/. If you skip this step, you must provide the path to the executable when you invoke docker or dockerd commands.

	$ sudo cp docker/* /usr/bin/
4、Start the Docker daemon:

	$ sudo dockerd &
  If you need to start the daemon with additional options, modify the above command accordingly or create and edit the file /etc/docker/daemon.json to add the custom configuration options.

5、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.

 根据以上步骤即可完成操作。

常见问题：

解决方法：

删掉 /var/lib/docker  文件夹

#> rm -rf  /var/lib/docker

重新启动，问题解决！

#> sudo dockerd &
