Test the TimesTen Operator

To test the TimesTen Operator, the test Pod uses the curl command to access the TimesTen Operator's readiness probe endpoint. If the TimesTen Operator self-reports that it is ready, the test succeeds.

The TimesTen Operator's readiness endpoint is exposed to the Kubernetes cluster through the TimesTen Operator's EXPOSE_PROBES manifest variable. In the default configuration (EXPOSE_PROBES=1), the TimesTen Operator creates a Kubernetes Service. This Service makes the endpoint available from within the cluster. You can prevent this Service from being created by setting probes.expose=0 in your customized YAML file. See The ttoperator Chart.

To test the TimesTen Operator, you test the ttoperator chart release running in your namespace. Let's test the TimesTen Operator.

1. Examine the ttoperator chart release.
