Cent OS converting a head less machine to full GUI machine

You shall need sudo access for all of these.

You might want to create a new user do as following

useradd <username>
passwd <username>
usermod -aG wheel <username>

Install GUI

// Update the machine first ? I like to do that often. You can skip it.

docker container run -it --rm --entrypoint=/bin/bash <image id>
// To transfer images from one host to another
