创建容器

三个容器的名称分别是Master、Slave1、Slave2

创建内部网络

[root@ecs-e722 ~]# docker network create --driver=bridge hadoop
f7b10710ffde328bf84b9d967ad2941b5acdbf52365c4f672cc7e54394234f6d
[root@ecs-e722 ~]# docker network ls

4797410ac497        none                null                local

创建master容器，开放端口

[root@ecs-e722 ~]# docker run -itd --network hadoop -h Master --name Master -p 9870:9870 -p 8088:8088 --restart=always registry.cn-hangzhou.aliyuncs.com/hadoop_test/hadoop_base /bin/bash
 * Starting OpenBSD Secure Shell server sshd                                                                                          [ OK ] 
root@Master:/# 

# --network hadoop ：指定该容器使用创建的hadoop网络
# --name Master ：把该容器名称命名为Master
# -p 9870:9870 ：将宿主机的9870端口号，映射到容器的9870端口
# -p 8088:8088 ： 将宿主机的8088端口号，映射到容器的8088端口

创建slave1容器，不开放端口

[root@ecs-e722 ~]# docker run -itd --network hadoop -h Slave1 --name Slave1 --restart=always registry.cn-hangzhou.aliyuncs.com/hadoop_test/hadoop_base /bin/bash
 * Starting OpenBSD Secure Shell server sshd                                                                                          [ OK ] 
root@Slave1:/# 

创建slave2容器，不开放端口

[root@ecs-e722 ~]# docker run -itd --network hadoop -h Slave2 --name Slave2 --restart=always registry.cn-hangzhou.aliyuncs.com/hadoop_test/hadoop_base /bin/bash
 * Starting OpenBSD Secure Shell server sshd                                                                                          [ OK ]
