If you want another beginner’s guide to Kubernetes networking, then check out our article on How Pods communicate in Kubernetes. The IP address of a Pod is normally accessible from inside a Kubernetes cluster only! You’ve got the IP address, but it doesn’t seem to be reachable. But wait… the IP address doesn’t seem to be reachable! If you have more than one container in a single Pod, the containers will all have the same IP address. I’m creating an Nginx pod with this YAML: Use kubectl to get a Pod’s IP addressĬreate a Pod, either directly or through a Deployment.
#What is kubernetes pods install
If you want a quick Kubernetes cluster to follow these instructions, I’m using k3s, which you can download and install locally, from. Specifically, the command kubectl get pod will give you information about Pods. You can get most information about the state of the Kubernetes cluster using the kubectl command, which fetches this info from the Kubernetes API. So you want to find out the IP address of a Pod from your terminal? It’s quite straightforward. Advertisements Find a Pod’s IP address from outside the Pod In this article, we’ll focus on finding it from outside the Pod (when you’re creating or configuring Pods), and then inside the Pod (when your application needs to know its IP address). There are a few reasons why you might want to find out the IP address of a Pod in Kubernetes – perhaps you’re doing some work inside the cluster, or perhaps you’re deploying applications which need to know their own IP. We’ll try to answer this question, and also learn why the IP address isn’t perhaps sufficient to do what you want to do. How do you get a Pod’s IP address, both inside the cluster and outside of it? So I thought about writing an article to answer this question: I realised that it’s really easy to get confused with Kubernetes networking – especially if you’ve not done much Linux and networking before!
We were discussing Pods and IP addresses in a new Kubernetes cluster.īut pretty quickly, we got deep into the weeds of port forwarding and routing and networking. I was in a meeting the other day (yes, it was dreamy). But how do you find out a Pod’s IP address? In Kubernetes, every Pod is assigned an IP address.
