Hello, I am learning terratest and observed a bug in the helm integration test example.

The error is

retry.go:103: HTTP GET to URL http://ct-control-plane:31166 returned an error: Get "http://ct-control-plane:31166": dial tcp: lookup ct-control-plane: no such host. Sleeping for 10s and will try again.

Seems the host is not accessible from outside of the cluster.

Full error:
