run-this.sh

#!/bin/bash

## Creates GKE (Google Kubernetes Engine) clusters in multiple zones, deploys
## application containers in the nodes and starts respective services
## on the deployed nodes

# Usage:
# ./run-this.sh <<M> <N_node-1_deploys> <N_node-2_deploys>...<N_node-M_deploys> <zone>>..
#
# Example:
#
# ./run-this.sh 2 2 stellar_deployment.json 1 torrent_deployment.json us-west1-a 1 2 stellar_deployment.json us-east4-a
#
# Will create a cluster of size 3 with 2 stellar nodes and 1 qBittorrent nodes
# in us-west1-a, and a cluster of size 2 with 2 stellar nodes in us-east4-a

# Note: If you want to create a cluster in every zone of a region, don't
#       specify the zone e.g. us-west1 instead of us-west1-a
