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.

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#

But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
