API Basics

(for full API, see Red5 Pro Stream Manager API)

Verify Stream Manager Controller (GET)

GET call:

https://<streammanager_URL>/streammanager/api/4.0/admin/debug/cloudcontroller?accessToken=<rest.administratorToken>

should return: Terraform Cloud Service

Create a Scale Policy (post)

  • Make sure to include a role section for each node type you want to include (origin, edge, relay, transcoder):

POST call:

https://<streammanager_URL>/streammanager/api/4.0/admin/configurations/scalepolicy?accessToken=<accessToken>

Data (make sure to select JSON as the body type):

   {
  "policy": {
          "name": "<policy-name>",
          "description": "<policy-description>>",
          "type": "<policy-type>",
          "version": "<policy-version>",
          "targets": {
              "region": [
                  {
                      "name": "default",
                      "target": [
        {
          "role": "<role>",
          "minLimit": "<min-node-count>",
          "maxLimit": "<max-node-count>",
          "scaleAdjustment": "<node-scale-adjustment>"
        }
      ]
    }
    }}

Create a Launch Policy (post)

For ease of administration, we recommend naming the policy something easily identifiable and descriptive, such as <imagename>-<nodetypes> (e.g., red5pro-11.0-origin-edge).

Image name

The image name will be the name of the VM that you configured to use as the node image.

Instance type

Terraform has predefined VM types for vSphere and we can change it in the terraform file: cloud_controller_vsphere_dhcp.tf

  • 2cpu_4mem — 2 cpu cores and 4gb memory
  • 4cpu_8mem — 4 cpu cores and 8gb memory
  • 8cpu_16mem — 8 cpu cores and 16gb memory
  • 16cpu_32mem — 16 cpu cores and 32gb memory
  • 32cpu_64mem — 32 cpu cores and 64gb memory

POST call:

https://<streammanager_URL>/streammanager/api/4.0/admin/configurations/launchconfig?accessToken=<accessToken>

Data (make sure to select JSON as the body type):

   {
    "launchconfig": {
      "name": "<configuration-name>",
      "description": "<configuration-descrption>",
      "image": "red5pro-11.0-template",
      "version": "0.0.3",

    "targets": {
        "target": [
      {
        "role": "<role>",
        "instanceType": "2cpu_4mem",
        "connectionCapacity": "<instance-capacity>"
      }
      ]
      },

      "properties": {
        "property": [
          {
            "name": "<property-name>",
            "value": "<property-value>"
          }
        ]
      },
      "metadata": {
        "meta": [
          {
            "key": "<meta-name>",
            "value": "<meta-value>"
          }
        ]
      }
    }}

Create a New Node Group (POST)

Using a tool like Postman, create a new node group via the API.

Region

You can use any region name for vSphere configuration, but you need to use the same value in the SM configuration red5-web.properties file as in node group creation. Example: private

  • In the SM configuration file: red5-web.properties — terra.regionNames=private
  • In the node group creation: “private”

POST call:

https://<streammanager_URL>/streammanager/api/4.0/admin/nodegroup?accessToken=<rest.administratorToken>

Data (make sure to select JSON as the body type):

{
 "regions": [
   "private"
 ],
  "launchConfig": "vsphere-launch-01",
  "scalePolicy": "vsphere-scale-01"
}

Note the cluster “name” that is returned by the above call. It will be used to create a new Origin server.

Launch New Origin (POST)

After you create a node group, create the origin server. Creating an origin server will also generate at least one edge, per scaling policy min limit.

https://<streammanager_URL>/streammanager/api/4.0/admin/nodegroup/<cluster-name>/node/origin?accessToken=<rest.administratorToken from red5-web.properties file>

Set Alarm Threshold (POST)

By default, the alarm threshold (the capacity percentage at which the cluster will scale up any given node type) is set to 60%. To modify this, POST the following:

FOR EDGE:

https://<streammanager_URL>/streammanager/api/4.0/admin/alarm/scaleout/default?type=edge&threshold=<threshold>&accessToken=<rest.administratorToken>

FOR ORIGIN:

https://<streammanager_URL>/streammanager/api/4.0/admin/alarm/scaleout/default?type=origin&threshold=<threshold>&accessToken=<rest.administratorToken>

FOR RELAY:

https://<streammanager_URL>/streammanager/api/4.0/admin/alarm/scaleout/default?type=relay&threshold=<threshold>&accessToken=<rest.administratorToken>

FOR TRANSCODER:

https://<streammanager_URL>/streammanager/api/4.0/admin/alarm/scaleout/default?type=transcoder&threshold=<threshold>&accessToken=<rest.administratorToken>

List Groups (GET)

https://<streammanager_URL>/streammanager/api/4.0/admin/nodegroup?accessToken=<rest.administratorToken>
