If preparing for a pod failed because the driver was not registered, it failed
after already having added the pod and claim to the claim info cache. The
effect was that deletion of the pod was blocked until the driver got
installed. Other errors had a similar effect. Now as many errors as possible
are checked in a read-only loop before proceeding to changing the claim info
cache.
The error message that was surfaced for the problem was not very readable:
Failed to prepare dynamic resources: failed to get gRPC client for driver dra-1411.k8s.io: plugin name dra-1411.k8s.io not found in the list of registered DRA plugins
To address this, error messages and wrapping get updated according to these
guidelines:
// Most errors returned by the manager show up in the context of a pod.
// They try to adher to the following convention:
// - Don't include the pod.
// - Use terms that are familiar to users.
// - Don't include the namespace, it can be inferred from the context.
// - Avoid repeated "failed to ...: failed to ..." when wrapping errors.
// - Avoid wrapping when it does not provide relevant additional information to keep the user-visible error short.
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.
