kubectl top says metrics aren't available. Your cluster is fine. Look at the terminal: kubectl get pods shows web-7d4b9 Running, one of one ready, zero restarts. Yet kubectl top pods fails with Metrics API not available. The pod is healthy, so something else is missing.

kubectl top doesn't measure anything itself. It only reads numbers. On the left, it points at an empty slot, because nothing is collecting usage. metrics-server, a small add-on, fills that slot by gathering CPU and memory from your nodes. Many fresh clusters ship without it.

On minikube, enable the addon with minikube addons enable metrics-server. Give it about a minute to collect its first numbers, then rerun kubectl top pods. Now you get a table. 3m means three millicores of CPU, and 42Mi is memory in mebibytes. These numbers are illustrative. Other clusters install metrics-server differently.

kubectl top can't read numbers no one is collecting. Whenever it errors, check whether metrics-server is installed and running first.
