{answer}

In this article, we will discuss how to enable HTTP API on a Kubernetes operator-based cluster and how to test it.

To enable this, a couple of variables needed to be updated. The variable settings are required to be updated in the memsql-cluster.yaml You will add the http_proxy_port and http_api settings.

The globalVariables the section must be declared under the aggregatorSpec.

...
  aggregatorSpec:
    globalVariables:
      http_proxy_port: "8080"
      http_api: "on"
...

After updating the settings, apply the configuration with the below command:

kubectl apply -f memsql-custer.yaml

Testing:

After HTTP API is enabled, you can call the GET /ping API request to verify that the HTTP service is running and connectable. To perform this action using cURL, invoke a GET request to the /ping endpoint with no parameters, as shown below.

curl https://localhost:8080/ping

If the HTTP API service is available and can respond to requests, you will receive the following response along with a 200 OK status code, indicating a successful HTTP response.
