$ oc idle <service>
As an OpenShift Container Platform administrator, you can idle applications in order to reduce the consumption of resources.
Applications are made of services, as well as other scalable resources, such as deployment configurations. The action of idling an application involves idling all associated resources.
Idling an application involves finding the scalable resources (deployment configurations, replication controllers, and others) associated with a service. Idling an application finds the service and marks it as idled, scaling down the resources to zero replicas.
Idle multiple services by creating a list of the desired services, then using the
--resource-names-file option with the
oc idle command.
This is helpful if an application spans across a set of services within a project, or when idling multiple services in conjunction with a script in order to idle multiple applications in bulk within the same project.
Create a text file containing a list of the services, each on their own line.
Idle the services using the
$ oc idle --resource-names-file <filename>
The idle command is limited to a single project. For idling applications across a cluster, run the idle command for each project individually.
Application services become active again when they receive network traffic and will be scaled back up their previous state. This includes both traffic to the services and traffic passing through routes.
Applications may be manually unidled by scaling up the resources. For example, to scale up a deploymentconfig, run the command:
$ oc scale --replicas=1 dc <deploymentconfig>
Automatic unidling by a router is currently only supported by the default HAProxy router.
