cat <cf> | om create	cat <cf> | kubectl create -f -
om ns1/sec/mysec create –from /etc/group	kubectl create -f secret.yml
Viewing and Finding
om “*” ls	kubectl get services kubectl get pods
om container.type=docker ls	kubectl get pods -o jsonpath=…
om <path> print config –format json	kubectl describe svc <svc>
Updating
om <path> set –kw ip#0.expose=80:8080/tcp	kubectl expose rc nginx –port=80 –target-port=8000
om <svc> set –kw env.icon_url=http://goo.gl/XXBTWq	kubectl annotate pods my-pod icon-url=http://goo.gl/XXBTWq
om <svc> get container#0.run_image | sed “s/(.*):.*$/1:v4/” | xargs om <svc> set –kw container#0.run_image	kubectl get pod mypod -o yaml sed “s/(image: myimage):.*$/1:v4/” kubectl replace -f -
om <svc> edit	kubectl edit svc/docker-registry
Scaling

Interacting with Nodes and Cluster
om node freeze –local om node freeze –node my-node	kubectl cordon my-node
om “**” stop –node my-node	kubectl drain my-node
om “**” thaw –node my-node	kubectl uncordon my-node
om daemon status –format json	kubectl cluster-info dump
