Centos 6.x 升級docker 1.7.1 至 docker 1.13.0

前言

  隨着docker的不斷升級，也提供更加豐富的功能，目前Centos6.x默認最新版本僅爲 Docker version 1.7.1, build 786b29d/1.7.1

  該版本對於docker的監控功能少之極少，爲了方便通過zabbix監控docker服務的性能，以下將docker升級至 1.13.0版本

環境

操作系統 ： centos 6.7

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

docker升級目前版本：Docker version 1.13.0

相關依賴環境：yum install udev udev-devel device-mapper-libs

操作

一、卸載docker服務，卸載之前請將容器及數據進行備份

  #> 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、上傳新版docker文件

 文件下載地址：https://download.docker.com/linux/static/stable/x86_64/ 

 將文件上傳服務器進行解壓 

 以下官方安裝說明

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.

 根據以上步驟即可完成操作。

常見問題：

WARN[0000] containerd: low RLIMIT_NOFILE changing to max  current=1024 max=4096
ERRO[0001] devmapper: Udev sync is not supported. This will lead to data loss and unexpected behavior. Install a dynamic binary to use devicemapper or select a different storage driver.      For more information, see https://docs.docker.com/engine/reference/commandline/daemon/#daemon-storage-driver-option

解決方法：

刪掉 /var/lib/docker  文件夾

#> rm -rf  /var/lib/docker

重新啓動，問題解決！

#> sudo dockerd &
