The -c flag in the kubectl exec command specifies which container in a pod you want to execute the command against. This is necessary when a pod has multiple containers, and you need to indicate which container should run the command. If the -c flag is not passed, the command is executed, however a messagem is popupd, and in automated scripts it invalidade the processo. The adition of -c will not affect the manual usage and will prevent erros in some automation process. Summary Use -c when the pod has multiple containers. It ensures you are executing the command in the correct container. Helps avoid unexpected behavior or errors when Kubernetes defaults to the wrong container.
