# 卸载旧版本docker
$ sudo yum remove docker \
                 docker-client \
                 docker-client-latest \
                 docker-common \
                 docker-latest \
                 docker-latest-logrotate \
                 docker-logrotate \
                 docker-selinux \
                 docker-engine-selinux \
                 docker-engine

# 安装依赖包
$ sudo yum install -y yum-utils

# 添加 yum 软件源
$ sudo yum-config-manager \
    --add-repo \
    https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
$ sudo sed -i 's/download.docker.com/mirrors.aliyun.com\/docker-ce/g' /etc/yum.repos.d/docker-ce.repo

# 更新 yum 软件源缓存,并安装 docker-ce
$ sudo yum install docker-ce docker-ce-cli containerd.io

# 使用脚本自动安装
$ curl -fsSL get.docker.com -o get-docker.sh
$ sudo sh get-docker.sh --mirror Aliyun

# 启动docker
$ sudo systemctl enable docker
$ sudo systemctl start docker

# 如果非root用户,用下面的命令加入docker组
$ sudo groupadd docker
$ sudo usermod -aG docker $USER

# 测试 Docker 是否安装正确,有下面的输出则安装成功
$ docker run --rm hello-world

Unable to find image 'hello-world:latest' locally

Digest: sha256:308866a43596e83578c7dfa15e27a73011bdd402185a84c5cd7f32a88b501a24
Status: Downloaded newer image for hello-world:latest

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:
