CentOS7 版本安装Docker

1、安装依赖包

[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2

2、添加Docker软件包源

[root@localhost ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

3、更新yum包索引

[root@localhost ~]# yum makecache fast

4、安装Docker CE版本

[root@localhost ~]# yum install docker-ce

5、查看版本

[root@localhost ~]# docker version

6、测试：

[root@localhost ~]# docker run hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:

7、卸载：

yum remove docker-ce
或着
rm -rf /var/lib/docker
