Kubernetes Gets a New Resource Orchestrator in the Form of Kro
- Kubernetes now has a new resource orchestrator called Kro, jointly developed by Amazon Web Services, Google, and Microsoft.
- Kro aims to simplify managing workloads on Kubernetes by grouping resources into reusable units, making deployments more efficient.
- It introduces the ResourceGraphDefinition (RGD) concept to declare collections of Kubernetes resources and their relationships.
- Kro uses the Common Expression Language (CEL) for logical operations and automatically determines the sequence for object creation.
- An RGD acts as a DAG for an application, managing dependencies and deployment sequence intelligently.
- Applications are created by defining a ResourceGraphDefinition that specifies the structure and resources for the workload.
- Kro offers advanced capabilities like automatic dependency management, allowing for easy customization and deployment of Kubernetes resources.
- Compared to Helm and Kustomize, Kro provides a more secure runtime with structured YAML and automatic dependency management based on a DAG.
- Kro has the potential to become a preferred tool for managing Kubernetes deployments, offering a comprehensive solution for resource orchestration.
- With support from AWS, Google Cloud, and Microsoft, Kro aims to make Kubernetes more accessible and efficient in the ecosystem.
