The Kubelet's DRA manager was failing to report device health status in a pod's status for certain types of resource claims. The logic incorrectly assumed that the claim name used within the container's spec (`container.resources.claims[*].name`) was the same as the metadata name of the actual ResourceClaim object. This assumption is false in two key scenarios: 1. When a claim is generated from a `ResourceClaimTemplate`, Kubernetes creates a `ResourceClaim` object with a randomized suffix in its name. 2. When a user defines a pre-existing claim in `pod.spec.resourceClaims`, they can provide a local name that differs from the actual `ResourceClaim` object's name. In both cases, the code would fail to find the claim's information in its internal cache, resulting in the health status not being populated, as reported in issue #134482. This fix corrects the logic by using `pod.Status.ResourceClaimStatuses` as the authoritative map to look up the actual, generated name of the `ResourceClaim` object. This ensures that both templated and renamed claims are resolved correctly before their health status is retrieved from the cache. Additionally, this change introduces a new node e2e test that specifically covers templated and renamed claims to prevent future regressions.
Kubernetes (K8s)
Kubernetes, also known as K8s, is an open source system for managing containerized applications across multiple hosts. It provides basic mechanisms for the deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If your company wants to help shape the evolution of technologies that are container-packaged, dynamically scheduled, and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using K8s
See our documentation on kubernetes.io.
Take a free course on Scalable Microservices with Kubernetes.
To use Kubernetes code as a library in other applications, see the list of published components.
Use of the k8s.io/kubernetes module or k8s.io/kubernetes/... packages as libraries is not supported.
To start developing K8s
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
git clone https://github.com/kubernetes/kubernetes
cd kubernetes
make
You have a working Docker environment.
git clone https://github.com/kubernetes/kubernetes
cd kubernetes
make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide, and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
Community Meetings
The Calendar has the list of all the meetings in the Kubernetes community in a single location.
Adopters
The User Case Studies website has real-world use cases of organizations across industries that are deploying/migrating to Kubernetes.
Governance
Kubernetes project is governed by a framework of principles, values, policies and processes to help our community and constituents towards our shared goals.
The Kubernetes Community is the launching point for learning about how we organize ourselves.
The Kubernetes Steering community repo is used by the Kubernetes Steering Committee, which oversees governance of the Kubernetes project.
Roadmap
The Kubernetes Enhancements repo provides information about Kubernetes releases, as well as feature tracking and backlogs.
