Centos7 Installing Docker steps

About Centos7 install Docker, as a beginner Baidu a lot, deeply feel the gap between Baidu and Google, Baidu encountered a variety of errors, basically and that a wall about, no way, directly search English documents, before installation, the following steps:

The original URL is http://www.liquidweb.com/kb/how-to-install-docker-on-centos-7/

Step 1:installation of Docker

As a matter of best practice we ' ll update our packages://Update your package

yum -y update                                            // 安装命令1

Now let's install Docker by installing the Docker-io Package://Installation via Docker-io pack

yum -y install docker docker-registry                        //安装命令2

Step 2:start Docker and make sure Docker starts on Boot

Set the Docker service to start on boot://Set to boot (do not know if there are any wooden translation pairs)

systemctl enable docker.service                             //安装命令3

Then start the Docker service://Start Docker Services

systemctl start docker.service                              //安装命令4

and verify your work by checking the status of Docker://View docker status

systemctl status docker.service                               //命令5

Step 3:download a docker Container//download Docker Container

Let ' s begin using docker! Download the CentOS Docker Image://start using Docker to download the CentOS Docker image

docker pull centos                                              //下载ceneos命令  注意：下载时候这句命令可能会因为网络原因报错，你要多试几次，等一等

Step 4:run a Docker Container//Run

Now, to the setup a basic <reference_page_text>centos container with a bash shell, we just run one command. <reference_page_text>docker run would run a command in a new container, <reference_page_text>-i attaches stdin And stdout, <reference_page_text>-t allocates a TTY, and we ' re using the Standard<reference_page_text>fedora Container.

docker run -i -t centos /bin/bash                                   //基本完成了到了这一步，这是打开，关闭使用exit这个单词命令就可以

That ' s it! You ' re now using a bash shell inside of a CentOS docker container.

To disconnect, or detach, from the shell without exiting use the escape sequence ctrl-p + ctrl-q.

There is many community containers already available, which can be found through a search. The command below I am searching for the keyword <reference_page_text>centos:

docker search centos                                             //这个是查询，失败了无所谓了，上面的步骤已经完毕了

If the error is reported, it is likely that your CentOS kernel has not been upgraded
