In case a malformed flag is passed to k8s components
such as "–foo", where "–" is not an ASCII dash character,
the components currently silently ignore the flag
and treat it as a positional argument.
Make k8s components/commands exit with an error if a positional argument
that is not empty is found. Include a custom error message for all
components except kubeadm, as cobra.NoArgs is used in a lot of
places already (can be fixed in a followup).
The kubelet already handles this properly - e.g.:
'unknown command: "–foo"'
This change affects:
- cloud-controller-manager
- kube-apiserver
- kube-controller-manager
- kube-proxy
- kubeadm {alpha|config|token|version}
- kubemark

- replace all stray calls of os.Exit() to util.CheckError() instead
- CheckError() now checks if the klog verbosity level is >=5
and shows a stack trace of the error
- don't call klog.Fatal in version.go
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Using GetFlagString from k8s.io/kubernetes/pkg/kubectl/cmd/util
causes pkg/client/clientset_generated/internalclientset to be pulled
as an external dependency, thus producing larger executable and
increasing the maintainance hell.

Fix boilerplates, comments in the code and make the output of kubeadm more user-friendly
Start using HostPKIPath and KubernetesDir everywhere in the code, so they can be changed for real
More robust kubeadm reset code now.
Removed old glog-things from app.Run()
Renamed /etc/kubernetes/cloud-config.json to /etc/kubernetes/cloud-config since it shouldn't be a json file
Simplification of the code
Less verbose output from master/pki.go
Cleaned up dead code
Start a small logging/output framework:
- fmt.Println("[the-stage-here] Capital first letter of this message. Tell the user what the current state is")
- fmt.Printf("[the-stage-here] Capital first letter. Maybe a [%v] in the end if an error should be displayed. Always ends with \n")
- fmt.Errorf("Never starts with []. Includes a short error message plus the underlying error in [%v]. Never ends with \n")
