Placement Policy

• URL:https://<root>/services/<serviceName.serviceType>/placementPolicy
  
• Operations:Edit Placement
• Required Capability: Default administrator role | Security and infrastructure
• Version Introduced:11.2

Description

The placementPolicy resource returns the current node affinity and tolerations that are applied to a GIS service’s pods. By utilizing node affinity and tolerations, administrators can have the pods for a specific service be scheduled to, or repelled from, specific nodes. For example, an administrator could use node affinity and tolerations to ensure that a GIS service’s pods are scheduled to nodes that have higher capacity, nodes that have a specific type of GPU, or prevent pods of other components from being scheduled on specific nodes. The placementPolicy resource also provides access to the Edit (Placement Policy) operation, which is used to define or modify the node affinity and toleration values for a specific service.
