Kubernetes–Open a bash prompt on a Pod

When using Kubernetes, sooner or later you’ll have a Pod that doesn’t work as expected. Last friday I blogged about what to do when your Pod is in a crash loop.

Today I’ll share a trick to open a shell on a Pod in trouble.

To open a Bash shell on a failing pod you can execute the following command:

kubectl exec –it <pod name> – bash

This will open a Bash shell on the specified pod:

PS /home/bart> kubectl exec -it example-pod-86f495c7f7-7s87g -- bash
root@example-pod-86f495c7f7-7s87g:/app#

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
