Ubuntu18.04安装docker

docker环境配置(ubuntu)

1. 安装docker

   $ sudo snap install docker
   

2. 安装docker-machine

   $ base=https://github.com/docker/machine/releases/download/v0.16.0 &&
     curl -L $base/docker-machine-$(uname -s)-$(uname -m) >/tmp/docker-machine &&
     sudo install /tmp/docker-machine /usr/local/bin/docker-machine
   

   检查是否成功：

   $ docker-machine version
   docker-machine version 0.16.0, build 9371605
   

3. 安装virtual box来作为docker-machine的driver：

   编辑/etc/apt/sources.list添加这行内容："deb https://download.virtualbox.org/virtualbox/debian bionic contrib"

   $ wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add - 
   $ sudo apt-get update 
   $ sudo apt-get install virtualbox-5.2
   

4. 创建一个docker-machine：

     $ docker-machine create --driver virtualbox default
     Running pre-create checks...

     Setting Docker configuration on the remote daemon...
     Checking connection to Docker...
     Docker is up and running!
     To see how to connect Docker to this machine, run: docker-machine env default
   

   查看创建是否成功：

   $ docker-machine ls
   NAME      ACTIVE   DRIVER       STATE     URL   SWARM   DOCKER    ERRORS
   default   -        virtualbox   Stopped                 Unknown   
   

   创建好之后最好重启一下

5. 修改docker的源：

   修改或新增/etc/docker/daemon.json

   # vi /etc/docker/daemon.json
   
   {
   
   "registry-mirrors": ["https://registry.docker-cn.com"]
   
   }
   
   
   

   $ systemctl restart docker.service
