deploy.sh

#!/bin/bash
#basic script to create the resources necessary for this deployment
# uses the node label: router-canary=true to determine what hosts should recieve the deployment
# default usage calls no arguments (will deploy to all router-pod host nodes), with desired replica of 1 pod (scale it up manaully to match routerpods) or convert to a daemonset

#options: 
#./deploy.sh --teardown (will destroy assets and remove from the cluster)
#./deploy.sh --testing (will create the objects but will not label all nodes, will assume you have pre-labeled nodes)
