>>/var/log/kube-apiserver.log not work for kubernetes1.6

Currently, under kubernetes1.5.3, kube-apiserver.log and kube-controller-manager.log is generated by adding '1>>/var/log/kube-apiserver.log 2>&1' in /etc/kubernetes/kube-apiserver.yaml file. When I upgrade the kubernetes version to 1.6.3, it not work. There is no log file created under /var/log. How to get the kubernetes log file? Thanks, much.

For kubernetes1.6+, try the following options

kube-apiserver

--audit-log-path=/var/log/kubernetes/kube-apiserver.log --logtostderr=false

and restart kube-apiserver, you can find all logs for kube-apiserver in file /var/log/kubernetes/kube-apiserver.log.

kube-controller-manager

--log-dir=/var/log/kubernetes --logtostderr=false

then restart kube-controller-manager, you will find:

  • ERROR logs in /var/log/kubernetes/kube-controller-manager.ERROR;
  • FATAL logs in /var/log/kubernetes/kube-controller-manager.FATAL;
  • INFO logs in /var/log/kubernetes/kube-controller-manager.INFO;
  • WARNING logs in /var/log/kubernetes/kube-controller-manager.WARNING;

kube-scheduler

 --log-dir=/var/log/kubernetes --logtostderr=false

ps -ef | grep kube
tail -f /var/log/message

See the kube* processes's options are configed right ?
And check the /var/log/message to find are there some errors about k8s?
