Update a Pod Defintion

Stopping Pods

A pod can be stopped by deleting its associated "pod" object:

oc delete pod/logging-fluentd-3kz30

The controller (either replication or DamonSet) will detect that the pod is missing and it will start a new one.

Scaling Down the Number of Replicas associated with a DeploymentConfig

Identify the name of the deployment config:

oc get dc -o name --selector=....

or

oc get dc

Then set the number of replicas to 0:

oc scale deploymentconfig/<deploymentconfig-name> --replicas=0
