I suggest we create/generate a ktew.env file. Use the same name on each host. The file will tell the what kind of node it should install, and all the information it needs.

json for etcd test

{
	"type": "etcd",
	"hostname": "k8s-etcd-03",
	"install": {
		"type": "remote",
		"location": "https://lighthouse.net:8000/clusters/4/k8s-etcd-01"
	},
	"etcd_cluster": [{
			"hostname": "k8s-etcd-01",
			"ip": "192.168.0.25",
			"version": "v3.2.11",
			"status": "not-ready"
		},
		{
			"hostname": "k8s-etcd-02",
			"ip": "192.168.0.26",
			"version": "v3.2.11",
			"status": "ready"
		},
		{
			"hostname": "k8s-etcd-03",
			"ip": "192.168.0.27",
			"version": "v3.2.11",
			"status": "ready"
		}
	]
}

Getting data we need :

export my_hostname=$(cat etcd.json | jq '.hostname' | tr -d \")
export my_ip=$(cat etcd.json | jq '.etcd_cluster[] | select (.hostname=="'$my_hostname'") | .ip' | tr -d \")

export other_ips=$(cat etcd.json | jq '.etcd_cluster[] | select (.hostname=="'$my_hostname'" | not) | .ip' | tr -d \" | tr '\n' ',' |  sed 's/,$//g')

export cluster_list=$(cat etcd.json | jq '.etcd_cluster[] | " \(.hostname)=https://\(.ip)"' | tr -d \" | tr '\n' ',' |  sed 's/,$//g')
