Kubernetes – Port-Forward To Kubernetes Service

Kubernetes service only available inside the cluster? Do you need to connect and test something? Port-forward from your client to the cluster! Only using kubectl.

The syntax is as follows:

~$ kubectl port-forward svc/[K8S_SERVICE] LOCAL_PORT:REMOTE_PORT

So let’s say you want to connect to a MySQL Service only available in the cluster network. And the service is called “mysql-service”:

~$ kubectl port-forward svc/mysql-service 31337:3306
Forwarding from 127.0.0.1:31337 -> 3306
Forwarding from [::1]:31337 -> 3306

The MySQL Service is now available under localhost:31337.

See you on the inside ?
