Installing Docker in a Linux environment

First contact with Docker, completely do not know how to install, and do not want to use a physical machine to experiment (mainly afraid of what problem = =), so in the virtual machine's Ubuntu system to try to install.

Various Baidu, Google looking for Docker installation tutorial, finally found the normal installation steps are as follows:

1. Execute the following command to install the optional kernel module package

$ sudo apt-get update$ sudo apt-get install\linux-image-extra-$ (uname-r) \linux-image-extra-virtual

2. Install using apt image source

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

3. Use domestic sources (faster)

① Adding a GPG key for a software source

$ Curl-fssl HTTPS://MIRRORS.ALIYUN.COM/DOCKER-CE/LINUX/UBUNTU/GPG | sudo apt-key add-

② Adding a Docker software source

$ sudo add-apt-repository \ "Deb [ARCH=AMD64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \ $ (LSB_RELEASE-CS) Stable

4. Installing Docker

$ sudo apt-get update$ sudo apt-get install Docker-ce

5. Automatic installation using scripts

$ curl-fssl get.docker.com-o get-docker.sh$ sudo sh get-docker.sh--mirror Aliyun

6. Start Docker

$ sudo systemctl enable docker$ sudo systemctl start docker

The start command for Ubuntu14.04 is

$ sudo service docker start

to here theoretically has been able to experience Docker happily, but I in the building environment always meet the online can find all the problems of the spirit, sure enough in the first step when there has been a problem, in the execution of the second command, the prompt:

Very desperate Ah, and then began to find a solution to this problem, then the goose nothing, and then began to engage in random mode, directly in the terminal input Docker, enter, incredibly magically appear

Look at this sentence, I inside cow face, feel like a fool, but still very excited, decisive input command:

sudo apt install Docker.io

Then there will be a prompt to continue the information, enter Yes, carriage return, static and so on after the command is OK

After the installation is complete, re-enter: Docker at the terminal, and the information that appears is a variety of tips:

It's not easy ^_^ But the result is still good. It may be because the Ubuntu version is constantly upgrading, so you can have this kind of operation
