Core Concept
Resource template: Karmada uses Kubernetes Native API definition for federated resource template, to make it easy to integrate with existing tools that already adopt on Kubernetes
Propagation Policy: Karmada offers standalone Propagation(placement) Policy API to define multi-cluster scheduling and spreading requirements.
- Support 1:n mapping of Policy: workload, users don't need to indicate scheduling constraints every time creating federated applications.
- With default policies, users can just interact with K8s API
Override Policy: Karmada provides standalone Override Policy API for specializing cluster relevant configuration automation. E.g.:
- Override image prefix according to member cluster region
- Override StorageClass according to cloud provider
The following diagram shows how Karmada resources are involved when propagating resources to member clusters.
