1. 準備centos映象
1、下載映象 docker pull centos:7.4:7.5.1804 2、啟動容器 [root@localhost ~]# docker run -d -p 8002:22 --privileged=true centos:7.5.1804 /usr/sbin/init 1b11913110f02391bd93bae273acfb6f357f2ce7bf7742eb01d267da80a690c7 # 注：-d 後臺啟動; -p 指定埠，這裡將centos容器的22埠對映到宿主機的8002埠 [root@localhost ~]# docker exec -it 1b11913110f02391bd93bae273acfb6f357f2ce7bf7742eb01d267da80a690c7 /bin/bash 3、檢視8002 埠動態 [root@localhost ~]# ps -aux|grep 8002 root 31662 0.0 0.2 364448 11160 ? Sl 14:01 0:00 /usr/bin/docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 8002 -container-ip 172.17.0.3 -container-port 22 root 33341 0.0 0.0 112668 972 pts/4 S+ 14:12 0:00 grep --color=auto 8002
2. 到容器中的操作
1、安裝工具 yum install net-tools -y yum install openssh openssh-server openssh-clients 2、啟動sshd systemctl start sshd systemctl restart sshd systemctl enable sshd 3.遠端連線容器 [root@localhost ~]# ssh root@宿主機ip -p 8002 The authenticity of host '[172.30.4.129]:8002 ([172.30.4.129]:8002)' can't be established.
