The only file needed in this repo to spawn a cluster with the application is the "makecluster.sh" bash script.
Create an account for google cloud engine (GCE). (console.cloud.google.com)
Enable Compute engine and Container engine API:
API manager > Library > Compute Engine API
API manager > Library > Container Engine API
Download a service account file in json format for your GCE project:
API manager > Credentials > Create credentials > Service account key (Use "Compute Engine default service account if you don't know what to pick")
You need to have docker installed. To install on debian or ubuntu, run: sudo apt-get install docker-ce.
Now run createall.sh and follow the instructions. A cluster with the application will be installed in a couple of minutes.
