Viewing namespace Pods

Restarting a Pod (scale down and up)

In order to scale-up (or scale-down) a set of Pods you will need to edit their Deployment, or StatefulSet, whichever is appropriate. The Fragalysis Stack Pod, for example, is managed by a StatefulSet. With Workloads -> StatefulSets selected (and the appropriate Stack’s namespace chosen in the namespace filter) click Stack to see the its description.

Click the pencil (Edit) Icon in the description banner to be presented with the YAML representation of the stack’s StatefulSet.

Scroll down if required to locate the replicas: field. To scale-down the Pods set this to 0 and then click Save & Close. To scale the Pods up, set this field to 1 or more.
