Get Shell Session into Kubernetes Worker Node

In my last post, I talked about connecting to a Azure Kubernetes (AKS) worker node using SSH. But sometimes, you might not have access to the private key used and don't want to update the key either.
Kubernetes provides a way to access worker node.

1. List Nodes

   kubectl get nodes -o wide
   

2. Connect to worker node

   kubectl debug node/<node> -it --image=mcr.microsoft.com/cbl-mariner/busybox:2.0
   

   Where:

   • node: name of the node

   For example, the following command will connect to aks-nodepool1-37663765-vmss000000

   kubectl debug node/aks-nodepool1-37663765-vmss000000 -it --image=mcr.microsoft.com/cbl-mariner/busybox:2.0
