Nodegroup Creation

To create a nodegroup which includes Relay nodes, use the launch configuration and scale policy which you created.

POST:

https://streammanager.com/streammanager/api/4.0/admin/nodegroup?accessToken=xyz123
{
"regions": [
 "us-east-1"
 ],
 "launchConfig": "oer-release560",
 "scalePolicy": "largeevent01"
}

Initiate the nodegroup by adding an origin and wait for all of the nodes to be inservice before broadcasting.
