Port forwarding

For troubleshooting purposes it is often practical to port forward a service in k8s.

This is also the only way to access certine admin interfaces that aren't exposed with an ingress

Generic service

This is the general way to expose any service with a port-forward. In a step to reduce the use of legacy IP, binding to ipv6 is forced in this example, note you might want to bind to ::1 instead of ::

kubectl -n NAMESPACE port-forward svc/SERVICE_NAME PORT:PORT --address="::"

Capacitor

If troubleshooting fluxcd, it might be nice to have a more visual representation of what services are in fluxcd.

For this purpose a capacitor deployment exists, but isn't exposed via any ingress for security reasons, to forward it run the following command

kubectl -n flux-system port-forward svc/capacitor 9000:9000 --address="::1"

Hubble-UI

For visualizing network flows

For this purpose a huble deployment exists, but isn't exposed via any ingress for security reasons, to forward it run the following command

kubectl port-forward -n kube-system svc/hubble-ui 8082:80 --address="::"
