type GeoLocationPlugin ¶

This GeoLocationPlugin ensures that a pod is placed in or close to its specified target geo-location. The plugin has two main functions:

• Filter: filter out nodes that are further away from the pod's desired target location than the max distance specified by the pod.
• Score: assign a score, based on how far (as a percentage of the max distance) the node is away from the target location

type GeoLocationPlugin struct {
}
