Deep dives
Introduction to Kubernetes Resource Orchestrator (KRO)
Kubernetes Resource Orchestrator (KRO) is a new cloud agnostic tool designed to simplify the grouping and management of Kubernetes resources for developers and platform administrators. By addressing the challenges of orchestration in Kubernetes, KRO enables platform teams to define repeatable patterns for resource consumption, enhancing the user experience for internal developers or data scientists. This initiative arose from discussions among professionals at leading cloud providers, fostering a collaborative effort to solve common problems faced in Kubernetes resource management. The resultant tool offers a mechanism to group all necessary resources, making deployment and maintenance more manageable and streamlined.
Jobsets and New Features in Kubernetes
The introduction of Jobsets marks a significant advancement in Kubernetes, offering an open-source API that allows users to manage distributed jobs as cohesive units. This feature simplifies operations by enabling users to submit Jobsets via a queuing system, helping to optimize cluster workloads and manage resource oversubscription effectively. By managing child jobs as a single entity, Jobsets enhances the usability of Kubernetes in handling complex job scheduling and workload management scenarios. These advances reflect the ongoing commitment to improve Kubernetes capabilities and usability for diverse applications.
KRO's Role in Simplifying Complex Deployments
KRO targets pain points associated with defining and managing complex Kubernetes deployments. Instead of requiring users to write extensive YAML files for standard applications like web services, KRO allows platform administrators to create a simplified Resource Graph Definition (RGD) that encapsulates complex configurations into a user-friendly format. For example, in a scenario involving deploying a web app, KRO can abstract multiple Kubernetes resources, such as deployments and load balancers, into a single, streamlined definition that reduces the risk of errors and simplifies the deployment process. This results in a more efficient workflow, enabling users to focus on functionality rather than managing numerous resource specifications.
Integrating Cloud Resources with Kubernetes
KRO's architecture supports not only native Kubernetes resources but also integrates seamlessly with external cloud services. This means that developers can define cloud resources—such as VPCs, storage buckets, or Kubernetes clusters—combined with Kubernetes components within the same RGD framework. The abstraction layer provided by KRO helps alleviate the complexity of managing these varied resources by allowing users to input only the necessary parameters while hiding underlying configurations. This capability not only streamlines the deployment of resources across different cloud providers but also empowers platform engineers to simplify their offering to developers, making self-service provisioning more accessible.
Today we welcome Jesse Butler and Nic Slattery to talk about the Kubernetes Resource Orchestrator, or KRO. Jesse works as a principal product manager at AWS and Nic is a Product Manager at Google. The Kubernetes Resource Orchestrator is a new cloud agnostic tool meant to simplify Kubernetes resources for devs and platform admins.
