I'm a complete newbie with Kubernetes, and have been trying to get secure CockroachDB running. I'm using the instructions and preconfigured .yaml files provided by Cockroach. https://www.cockroachlabs.com/docs/stable/orchestrate-cockroachdb-with-kubernetes.html
I'm using the Cloud Shell in my Google Cloud console to set everything up. Everything goes well, and I can do local SQL tests and load data. Monitoring the cluster by proxying to localhost, with the comnmand below starts off serving as expected
kubectl port-forward cockroachdb-0 8080
However, when using cloud shell web preview on port 8080 to attach to localhost, the browser session returns "too many redirects".
My next challenge will be to figure out how to expose the cluster on a public address, but for now I'm stuck on what seems to be a fairly basic problem. Any advice would be greatly appreciated.
Just to make sure this question has an answer, the problem was that the question asker was running port-forward from the Google Cloud Shell rather than from his local machine. This meant that the service was not accessible to his local machine's web browser (because the Cloud Shell is running on a VM in Google's datacenters).
The ideal solution is to run the kubectl port-forward command from his own computer.
Or, barring that, to expose the cockroachdb pod externally using the kubectl expose pod cockroachdb-0 --port=8080 --type=LoadBalancer as suggested in the comments.
