How to: setup a VM or Docker env

1. first need to select a base image.
   • VM : lubuntu/ubuntu easiest, fedora safer but more complicated.
   • Docker: centos6 small fedora OS.
2. run update the image with the package management.
3. run install base-compliers and project required languages and package managers
4. setup the users chmod and download any code base or tools
5. sometimes with enterprise firewall, you need to insert certs in browser.
6. If there are any custom configs like environment variables/paths.
   • leave the script that sets these thing up. because if i run system updates, those info might be lost. (my experience, docker image, port forwarding gone when i updated)
