I cannot access my Cassandra database, deployed on the same namespace in kubernetes.
My service has no cluster IP but an internal endpoint cassandra.hosting:9042 but whenever I try to connect from an internal spring application using
spring.data.cassandra.contact-points=cassandra.hostingit fails with the error All host(s) tried for query failed
How did you configure your endpoint? Generally, all services and pods in a Kubernetes cluster are discoverable through a standard DNS notation. It looks like this:
<service-name>.<namespace>.svc.cluster.local # or
<pod-name>.<namespace>.svc.cluster.local # or
<pod-name>.<subdomain>.<namespace>.svc.cluster.localIf you are within the same namespace this would work too:
<service-name>
<pod-name>
<pod-name>.<subdomain>I would also check either core-dns or kube-dns are running and ready:
kubectl -n kube-system get pods | grep dns
