Kubemq GCP Cloud Functions Target Connector

Kubemq gcp Cloud Functions target connector allows services using kubemq server to access call a function target on gcp Cloud Function. The connector synchronously invokes a deployed Cloud Function, very limited traffic is allowed 16 per 100 seconds.

Prerequisites

The following are required to run the redis target connector:

• kubemq cluster
• Gcp Cloud function targe.
• kubemq-targets deployment

Configuration

Kafka source connector configuration properties:

Properties Key	Required	Description	Example
project	yes	gcp project name	"testproject"
credentials	yes	gcp service account key location (json)	"TestTopic"
location_match	no	match missing function location (default true)	"true"

Example:

bindings:
  - name: kubemq-query
    source:
      kind: kubemq.kubemq.query
      name: kubemq-query
      properties:
        address: "kubemq-cluster:50000"
        client_id: "kubemq-query-gcpfucntions-connector"
        auth_token: ""
        channel: "query.gcp.functions"
        group:   ""
        auto_reconnect: "true"
        reconnect_interval_seconds: "1"
        max_reconnects: "0"
    target:
      kind: gcp.cloudfunctions
      name: target-gcp-couldfunctions
      properties:
        project: "testproject"
        credentials: "myKey"
        location_match: "true"

Usage

Get Request

Get request metadata setting:

Metadata Key	Required	Description	Possible values
name	yes	name of the gcp function	"test_function"
project	no	gcp project name (override parent value)	"testproject1"
location	no	gcp project location (missing value will be matched)	"us-central1"

Example:

{
  "metadata": {
    "name": "test_function",
    "location": "us-central1"    
  },
  "data": "eyJtZXNzYWdlIjoidGVzdCJ9"
}
