如何升级Docker

如何升级Docker

如何升级Docker取决于你是如何安装Docker的。

1. 使用 apt-get

   # Add the Docker repository key to your local keychain
   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
   
   # Add the Docker repository to your apt sources list.
   sudo sh -c "echo deb https://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
   
   # update your sources list
   sudo apt-get update
   
   # install the latest
   sudo apt-get install lxc-docker
   

2. 手工安装

   # kill the running docker daemon
   killall docker
   
   
   # get the latest binary
   wget http://get.docker.io/builds/Linux/x86_64/docker-latest -O docker
   
   # make it executable
   chmod +x docker
   
   
   # start the new version -d是指以守护进程的方式执行， & 指在后台执行
   sudo ./docker -d &
