Unlocking the Power of Kubernetes: A Guide on How to SSH into a Pod

Kubernetes has revolutionized container orchestration, providing a scalable and efficient platform for managing containerized applications. However, there are times when you need to troubleshoot or debug issues within a specific pod. In such cases, having the ability to SSH into a Kubernetes pod can be invaluable. In this guide, we'll walk you through the process step by step, demystifying the SSH access to Kubernetes pods.


Before diving into the SSH magic, make sure you have the following prerequisites in place:

  1. Kubectl Installed:
    Ensure that the Kubernetes command-line tool, kubectl, is installed on your local machine. If not, you can download it from the official Kubernetes website.

  2. Access to Kubernetes Cluster:
    You should have access to a Kubernetes cluster and the necessary permissions to interact with it using kubectl.

Step 1: Identify the Pod:

The first step is to identify the pod you want to SSH into. You can list all the pods in a namespace using the following command:

kubectl get pods -n <namespace>

Choose the pod you want to access and note its name.

Step 2: Retrieve Pod's Namespace:

To retrieve the namespace of the chosen pod, use the following command:

kubectl get pod <pod-name> -o=jsonpath='{.metadata.namespace}'

Make a note of the namespace for the subsequent steps.

Step 3: Open SSH Session:

Now that you have the pod name and namespace, you can open an SSH session to the pod. Use the following command, replacing <namespace> and <pod-name> with your actual values:

kubectl exec -it <pod-name> -n <namespace> -- /bin/bash

This command opens an interactive shell session (/bin/bash) within the specified pod.

Step 4: Explore the Pod:

Congratulations! You're now inside the pod. You can navigate, inspect files, and execute commands just as if you were working on a regular server.

# Example: List files in the pod's home directory
ls ~

Step 5: Exit the SSH Session:

Once you've completed your tasks inside the pod, you can exit the SSH session by typing:


More Examples:

Example 1: Executing Commands Directly

You can also execute commands directly without entering an interactive shell. For instance:

kubectl exec <pod-name> -n <namespace> -- ls /app

This command lists the contents of the /app directory in the specified pod.

Example 2: Copy Files to/from Pod

Use the kubectl cp command to copy files between your local machine and the pod:

# Copy a local file to the pod
kubectl cp /path/to/local/file.txt <namespace>/<pod-name>:/path/in/pod/file.txt

# Copy a file from the pod to your local machine
kubectl cp <namespace>/<pod-name>:/path/in/pod/file.txt /path/to/local/file.txt
