Provide CloudEvents around the management of (Cluster)TriggerAuthentication resources

[tomkerkhove]

Proposal

Event Types

• keda.authentication.triggerauthentication.created.v1
• keda.authentication.triggerauthentication.updated.v1
• keda.authentication.triggerauthentication.removed.v1
• keda.authentication.clustertriggerauthentication.created.v1
• keda.authentication.clustertriggerauthentication.updated.v1
• keda.authentication.clustertriggerauthentication.removed.v1

Events scoped to the cluster should not have the “namespace” segment in the subject.

Payload:

{
    "specversion" : "1.0",
    "type" : "keda.authentication.triggerauthentication.created.v1",
    "subject" : "/{kubernetes-cluster-name}/{namespace, only if it’s namespaces}/{cluster-trigger-authentication or trigger-authentication}/{resource-name}/",
    "time" : "2018-04-05T17:31:00Z",
    "datacontenttype" : "application/json",
    "data" : {
      "podIdentity": {
         "provider": "azure"
      },
      "secretTargetRef": [
        {
          "parameter": "<parameter-name>",
          "name": "<secret-name>",
          "key": "<secret-key-name>"
        }
      ],
      "environmentVariables": [
        {
          "parameter": "<parameter-name>",
          "name": "<environment-variable-name>",
          "containerName": "<container-name>"
        }
      ],
      "hashiCorpVault": {
         // Omitted, follow current configuration spec
      },
      "azureKeyVault": {
         "vault": {
           "vaultUri": "<URL>",
           "resourceUrl": "<URL>",
           "cloud": {
             "type": "AzurePublicCloud"
           }
         },
         "activeDirectory": {
           "client": {
             "id": "<id>",
             "secretKeyRef": {
               "name": "<secret-name>"
               "key": "<secret-key-name>"
             }
           }
           "endpoint": "<ad-endpoint-url>",
         }
      }
   }
}

Use-Case

Allow end-users to react to changes to their (Cluster)TriggerAuthentication resource.

Anything else?
