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 3389-->3389

 
docker run -it --privileged -d -v=/home/user/centos6_9_docker:/home/user/folder  --net=bridge --name  x1  -p 172.20.10.5:3389:3389 "mylinux:v1"

host 進入container x1

 
docker attach x1

切換至 oracle, 設定 vnc server password

 
su oracle
vncpasswd
exit

回到 root, 啟動 vnc server及 xrdp

 
service vncserver restart
service xrdp restart

測試連線 to container x1

 
用 windows mstsc, 遠端連至 172.20.10.5
用 oracle/oracle登入即可

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
