Here’s one for your toolbox, but use with care. Say you have an app running on kubernetes in a pod and you spot something you want to change. This is one way to get it done.
For the example, I spun up an nginx server called webapp.
The command to edit a resource running on kubernetes is kubectl edit <thing> <name>. So here goes:
kubectl edit pod webapp You’ll see a whole bunch of yaml that represents the pods definition.
