I have a MySQL pod running in my cluster.
I need to temporarily pause the pod from working without deleting it, something similar to docker where the docker stop container-id cmd will stop the container not delete the container.
Are there any commands available in kubernetes to pause/stop a pod?
So, like others have pointed out, Kubernetes doesn't support stop/pause of current state of pod and resume when needed. However, you can still achieve it by having no working deployments which is setting number of replicas to 0.
kubectl scale --replicas=0 deployment/<your-deployment>
see the help
# Set a new size for a Deployment, ReplicaSet, Replication Controller, or StatefulSet.
kubectl scale --help
Scale also allows users to specify one or more preconditions for the scale action.
If --current-replicas or --resource-version is specified, it is validated before the scale is attempted, and it is
guaranteed that the precondition holds true when the scale is sent to the server.
Examples:
# Scale a replicaset named 'foo' to 3.
kubectl scale --replicas=3 rs/foo
# Scale a resource identified by type and name specified in "foo.yaml" to 3.
kubectl scale --replicas=3 -f foo.yaml
# If the deployment named mysql's current size is 2, scale mysql to 3.
kubectl scale --current-replicas=2 --replicas=3 deployment/mysql
# Scale multiple replication controllers.
kubectl scale --replicas=5 rc/foo rc/bar rc/baz
# Scale statefulset named 'web' to 3.
kubectl scale --replicas=3 statefulset/web
