Developing a Node policy
The Node policy, which is also made up of Properties and Constraints, completes the full picture of services being deployed on the target Edge nodes.
Typically, the node policy specifies a set of properties that are matched against the constraints of the service policy and the deployment policy to ascertain which services will be deployed on a particular edge node. Multiple edge nodes may have the same set of properties, thus enabling them to receive the same qualifying services.
This Edge node property-based qualification working with the constraints of the services, as specified in the service and deployment policies, allows the service deployment to be scaled to many edge nodes automatically. The same is true for undeploying the services. By simply modifying the constraints in the deployment policy or the properties in the node policy, services can be undeployed on the Edge node.
The Node policy can be modified on the Edge node or in the Open Horizon...
