ubuntu 16.04 ock docker

Ubuntu's software source configuration file is /etc/apt/sources.list

Change the domestic one, or you will be crazy. The following is the drop of Tsinghua University:

# The source image is commented by default to improve the speed of apt update, if necessary, you can uncomment it yourself
deb https: // mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse 
# deb-src https: // mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse 
deb https: // mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse 
# deb-src https: // mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse 
deb https : // mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse 
# deb-src https: // mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb https: // mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse 
# deb-src https: // mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse

Then reboot the server.

$ sudo apt-get update

$ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

$ sudo apt-key fingerprint 0EBFCD88

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

$ sudo apt-get update

$ sudo apt-get install docker-ce

Then configure a docker accelerator

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://xxxxxxxxx.m.daocloud.io

Then according to the prompt, restart the docker service, enter docker info, and you can see the docker situation~
