Kubernetes port-forwarding for dev

September 26, 2021 kubernetes

Hey everybody, thanks for signing up for my email list. I’m going to try to send something out at least weekly.

This first newsletter I want to highlight a very useful Kubernetes feature that I started leveraging recently: port forwarding.

You can bind a port from a kubernetes cluster to your development machine you can hit private endpoints on your kubernetes cluster.

In the past week I’ve used it to access private endpoints and leverage a datadog agent that was on a cluster but not on my local development machine.

Here’s an example of how to do it:

$ kubectl get pods -A
...
$ kubectl port-forward <pod-name> <local port>:<remote port>

Now, whenever you hit localhost:, you’ll be hitting the container in your cluster.

For more information, see the documentation.
