My custom Zsh theme. extract into ~/.oh-my-zsh/custom/themes/ then add it to .zshrc with `omz theme set doctoruseful`.

Running Minecraft on a Google Compute Engine centos 7 instance. Or any other cloud VM.

First, you'll need to spin up a Google Compute Engine instance using your favourite Linux Distro. I like CentOS 7 :)

Make sure:

  • Use Ephemeral IP address (sticky to the instance, not static)
  • Set up the port for the default 25565 (I think) - needs a firewall?

Also you'll have to change the port that the minecraft server runs on, because the GCE is only open on https or http.
