Interactive droplet spawn tool using doctl and bash

gib-server.sh

#!/bin/bash

#todo is found at the top and randomly in the script

#spin for sleep time

#needs a better implementation than wait n seconds to ssh - something like "wait for droplet status to become active"

#allow to use custom image_slug

#don't exit when fail, return to type the number correctly

#needs to check if doctl is installed and redirect accordingly, same goes for token apply
