CMD ["/bin/sh /etc/init.d/sshd start"]

清除image

 
sudo docker ps -a -q | xargs -n 1 -I {} sudo docker rm -f {} && docker rmi mylinux:v1

Build image mylinux:v1

 
sudo docker build -t="mylinux:v1" .

啟動 container x1, port 1022-->22

 
docker run -it --privileged -d -v=/home/user/centos6_9_docker:/home/user/folder  --net=bridge --name  x1  -p 1022:22 "mylinux:v1"

host 進入container x1

 
docker attach x1

container x1中啟動 sshd, 並更改root password

 
/etc/init.d/sshd start
passwd

測試連線 to container x1

 
ssh root@hostip -p 1022
