Rosetta Stone

If you are coming from another clusterware or orchestrator, these tables map the command you know to its OpenSVC equivalent.

Orchestrators

Creating objects

OpenSVC	Kubernetes
`om <path> create --config ./manifest.conf`	`kubectl create -f ./my-manifest.yaml`
`cat <cf> \| om <path> create --config=-`	`cat <cf> \| kubectl create -f -`
`om ns1/sec/mysec key add --name grp --from /etc/group`	`kubectl create -f secret.yml`

Viewing and finding

OpenSVC	Kubernetes
`om '*' ls`	`kubectl get services` `kubectl get pods`
`om container.type=docker ls`	`kubectl get pods -o jsonpath=...`
`om <path> config show`	`kubectl describe svc <svc>`
`om <path> instance status`	`kubectl describe pod <pod>`

Updating

OpenSVC	Kubernetes
`om <path> config update --set ip#0.expose=80:8080/tcp`	`kubectl expose rc nginx --port=80 --target-port=8000`
`om <path> config update --set env.icon_url=http://goo.gl/XXBTWq`	`kubectl annotate pods my-pod icon-url=http://goo.gl/XXBTWq`
`om <path> config edit`	`kubectl edit svc/docker-registry`

Deleting

OpenSVC	Kubernetes
`om foo,baz purge`	`kubectl delete pod,service baz foo --all`
`om env.name=myLabel instance delete`	`kubectl delete pods,services -l name=myLabel`

Interacting with resources

OpenSVC	Kubernetes
`om <path> logs`	`kubectl logs my-pod`
`om <path> logs -f`	`kubectl logs -f my-pod`
`om <path> container logs`	`kubectl logs my-pod -c my-container`
`om <path> container enter --rid container#1`	`kubectl exec -it my-pod -- sh` `kubectl attach my-pod -i`

Interacting with nodes and cluster

OpenSVC	Kubernetes
`om node freeze` `om node freeze --node my-node`	`kubectl cordon my-node`
`om '**' instance stop --node my-node`	`kubectl drain my-node`
`om node unfreeze --node my-node`	`kubectl uncordon my-node`
`om cluster status --output json`	`kubectl cluster-info dump`
`om node config update --set env.dedicated=special_user` plus a node selector in `nodes`	`kubectl taint nodes foo dedicated=special-user:NoSchedule`
