简易的Docker版本升级方法

    1、使用 apt-get
    # Add the Docker repository key to your local keychain
    复制代码
    代码如下:
    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
    # Add the Docker repository to your apt sources list.
    复制代码
    代码如下:
    sudo sh -c "echo deb /uploads/202404/24/2301 docker main > /etc/apt/sources.list.d/docker.list"
    # update your sources list
    复制代码
    代码如下:
    sudo apt-get update
    # install the latest
    复制代码
    代码如下:
    sudo apt-get install lxc-docker
    2、手工安装
    # kill the running docker daemon
    复制代码
    代码如下:
    killall docker
     
    # get the latest binary
    复制代码
    代码如下:
    wget http://get.docker.io/builds/Linux/x86_64/docker-latest -O docker
    # make it executable
    复制代码
    代码如下:
    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
    复制代码
    代码如下:
    sudo ./docker -d &
    升级的一次实际操作记录：# docker ps 查看运行中的docker容器进程
    复制代码
    代码如下:
    [root@AY140716133600881bf5Z ~]# docker ps
