安装所需的依赖

yum install -y yum-utils device-mapper-persistent-data lvm2

添加centos7和docker的yum源

curl -o /etc/yum.repos.d/Centos-7.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-altarch-7.repo(arm)
curl -o /etc/yum.repos.d/docker-ce.repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

建立缓存

yum makecache fast

安装docker-20.10.8

yum -y install  docker-ce-20.10.8-3.el7 docker-ce-cli-20.10.8-3.el7

配置

创建配置目录，编辑配置文件

mkdir /etc/docker
vi /etc/docker/daemon.json
{
  "registry-mirrors": ["https://*******.mirror.aliyuncs.com"],
  "insecure-registries":["xxxx.xxxx.xxxx:5000"],
  "data-root": "/data/docker",
  "log-driver":"json-file",
  "log-opts": {"max-size":"1024m", "max-file":"2"}
}

registry-mirrors ：配置镜像加速
insecure-registries：忽略ssl证书验证（地址修改为需要的地址）
data-root：配置docker存储目录
log-opts: 配置容器日志的大小限制和数量
