Docker 支持 64 位版本 CentOS 7/8，并且要求内核版本不低于 3.10。 CentOS 7 满足最低内核的要求，但由于内核版本比较低，部分功能（如 overlay2 存储层驱动）无法使用，并且部分功能可能不太稳定。
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
执行以下命令安装依赖包：
sudo yum install -y yum-utils
鉴于国内网络问题，强烈建议使用国内源，官方源请在注释中查看。
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 # 官方源 # sudo yum-config-manager # --add-repo # https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install docker-ce docker-ce-cli containerd.io
sudo systemctl enable docker sudo systemctl start docker
输入：
docker run --rm hello-world
看见如下内容则成功安装！
docker run --rm hello-world
Unable to find image ‘hello-world:latest‘ locally

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

如果在 CentOS 使用 Docker 看到下面的这些警告信息：
WARNING: bridge-nf-call-iptables is disabled WARNING: bridge-nf-call-ip6tables is disabled
请添加内核配置参数以启用这些功能：
sudo tee -a /etc/sysctl.conf <<-EOF net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1 EOF
然后重新加载 sysctl.conf 即可
sudo sysctl -p
