1、通过 RPM 安装 docker 17.03.0 版本并且配置 docker 阿里加速
#安装必要的一些系统工具
yum install -y yum-utils device-mapper-persistent-data lvm2
#添加软件源信息
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#更新Docker-CE
yum makecache fast
#列出docker版本信息
yum list docker-ce.x86_64 --showduplicates | sort -r
#安装指定docker版本
yum -y install docker-ce-17.03.0.ce-1.el7.centos docker-ce-cli-17.03.0.ce-1.el7.centos
#配置docker加速
浏览器打开http://cr.console.aliyun.com,注册或登录阿里云账号,点击左侧的镜像加速器,将会得到一个专属的加速地址
mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://si7y70hh.mirror.aliyuncs.com"]
}
EOF
systemctl daemon-reload
systemctl restart docker
2、通过 docker 安装一个 LAPM 架构
[root@ubuntu1804 ~]#docker pull centos
[root@ubuntu1804 ~]#docker run -p 80:80 -itd --name centos centos
[root@ubuntu1804 ~]#docker exec -it centos bash
[root@d1fb2b5c2187 /]# dnf -y install httpd php php-mysqlnd mariadb-server
[root@d1fb2b5c2187 /]# /usr/sbin/httpd

#停止一个 docker 容器的时候自动删除该容器
[root@ubuntu1804 ~]#docker run --rm alpine cat /etc/issue
Welcome to Alpine Linux 3.11
Kernel \r on an \m (\l)
[root@ubuntu1804 ~]#docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4、写出 docker run 命令在自动启动 docker 服务时通过什么参数能够启动 docker 中的容器,从而实现容器随着 docker 服务的启动而自动启动
[root@ubuntu1804 ~]#docker run -d --name nginx --restart=always -p 80:80 nginx
[root@ubuntu1804 ~]#reboot
[root@ubuntu1804 ~]#docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
