No endpoints available for service

One of the most subtle issues to hunt down is why isn't my service acting as I expect? A common error to see in these cases is this message:

no endpoints available for service

If you have created a deployment and a service together, and everything seems to be running, but when you access the service endpoint you see this output:

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {
    
  },
  "status": "Failure",
  "message": "no endpoints available for service \"flask-service\"",
  "reason": "ServiceUnavailable",
  "code": 503
}

In this case, I received this message when using kubectl proxy to access the service endpoint flask-service through the proxy using the URL:

http://localhost:8001/api/v1/proxy/namespaces/default/services/flask-service ...
