A new Workload Conformance Working Group has been established in the Kubernetes community to create a shared standard for runtime workload behavior. This initiative aims to address the lack of a standardized way to test workloads themselves, unlike existing checks for clusters. Currently, cluster operators manually assess applications for issues like disruption tolerance and API version dependencies, leading to duplicated effort. The working group plans to deliver a specification detailing workload behavior for each Kubernetes minor version, a method for testing these requirements, and upstream conformance tooling. Areas of focus include security, resilience, resource usage, networking, storage, API interaction, and observability. Importantly, the specification will focus on how workloads run, not their application logic, and will require objective, testable requirements. SIG Architecture will own the specification and tooling, while SIG Apps will contribute the application perspective. The group will collaborate with other SIGs when requirements overlap with their domains. They aim for a stable first specification and tests within two to three Kubernetes release cycles. Community input is crucial, and involvement is encouraged through Kubernetes Slack and a mailing list.
