2fc19136c1 kubeadm: print the stack trace of an error for klog level v>=5
- 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

7d5ece2e2c kubeadm: move klog.InitFlags into app/kubeadm.go 2019-07-09 10:42:22 +08:00

Remove duplicate error messages from cli commands
Since we never use the cobras "SilenceErrors" or "SilenceUsage",
a command executed with "cmd.Execute()" will never return an error
without printing it.

The current behavior results in all error messages being printed twice:

Example:

$ kubectl abc
Error: unknown command "abc" for "kubectl"
Run 'kubectl --help' for usage.
unknown command "abc" for "kubectl"

This applies to all cli commands using Cobra. To verify, follow the code
path of the Execute function:

Move from glog to klog
- 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

810e9e107f Refactor the whole binary, a lot of changes in one commit I know, but I just hacked on this and modified everything I thought was messy or could be done better.
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")

16b159c12b kubeadm implement preflight checks
Includes checks for verifying services exist and are enabled, ports are
open, directories do not exist or are empty, and required binaries are
in the path.

Checks that user running kubeamd init and join is root and will only execute
command if user is root. Moved away from using kubectl error handling to
having kubeadm handle its own errors. This should allow kubeadm to have
more meaningful errors, exit codes, and logging for specific kubeadm use
cases.
