    Compare yaml files in path(s) to running state in kubernetes and print the
    differences. This is useful to ensure you have applied all your changes
    to the appropriate environment. This tools runs kubectl, so unless your
    ~/.kube/config is configured for the correct environment, you will need
    to supply the kubeconfig for the appropriate environment.

positional arguments:
  paths                  path(s) from which kubediff will look for configuration files

optional arguments:
  -h, --help            show this help message and exit
  --kubeconfig KUBECONFIG, -k KUBECONFIG
                        path to kubeconfig
  --context CONTEXT, -c CONTEXT
                        name of kubeconfig context to use
  --namespace NAMESPACE, -n NAMESPACE
                        Namespace to assume for objects where it is not specified (default = Kubernetes default for current context)
  --json, -j            output in json format
  --no-error-on-diff, -e
                        don't exit with 2 if diff exists
