Creating Objects

om create –config ./my-manifest.json

kubectl create -f ./my-manifest.yaml

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

om foo scale –to 3

kubectl scale –replicas=3 rs/foo

om foo,bar scale –to 3

kubectl scale –replicas=3 rs/foo rs/bar

Deleting

om foo,baz purge

kubectl delete pod,service baz foo –all

om env.name=myLabel delete –unprovision

kubectl delete pods,services -l name=myLabel

Interacting with Resources

om foo logs om foo logs –local

kubectl logs my-pod

om foo -f logs

kubectl logs -f my-pod

om foo docker run -it busybox sh

kubectl run -i –tty busybox –image=busybox – sh

om foo docker attach -i {container#1}

kubectl attach my-pod -i

om foo docker exec {container#1} ls /

kubectl exec my-pod -c my-container – ls /

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

om node set –kw env.dedicated=special_user # plus constraints or node selector in services

kubectl taint nodes foo dedicated=special-user:NoSchedule
