Before, the default value set for the `--kubeconfig` flag prevented the `KUBECONFIG` env variable to be ever taken into consideration. This behavior has now been fixed. If `--kubeconfig` flag is set, it takes precedence over the `KUBECONFIG` env variable. fixes #331 Signed-off-by: Patrick Pichler <git@patrickpichler.dev> Co-authored-by: Patrick Pichler <git@patrickpichler.dev>
