Because I want to install docker and build k8s on Centos7. The plan is to have one master and two nodes. In order to save time, I first installed docker and k8s on one Centos7, and then directly copied it to get another Centos7. Simple convenient
step
1 Select clone
2 The most important thing - MAC address setting must select "Include all network card MAC addresses"
This is for the case of using docker to build k8s. If you don’t choose this, the network card settings will be incomplete, which will affect subsequent operations. I mainly recorded it for this purpose.
3 Just click by default
Copying is very fast. After it is done, you can get a Centos7 with the same except for the IP address. It is convenient~
