Newbie question regarding restarting application after config change


I’m new to Kubernetes and trying and have my first application running. This is a homelab setup with 4 Raspberry Pi’s running k3s. I have blocky running. My question is, when I make a blocky config change how do I restart/reload the app short of tearing it down and deploying again.

Sorry for the entry level question…I have been researching but I’m not finding the answer.

Thanks in advance
