In contrast to the original HandleError and HandleCrash, the new HandleErrorWithContext and HandleCrashWithContext functions properly do contextual logging, so if a problem occurs while e.g. dealing with a certain request and WithValues was used for that request, then the error log entry will also contain information about it. The output changes from unstructured to structured, which might be a breaking change for users who grep for panics. Care was taken to format panics as similar as possible to the original output. For errors, a message string gets added. There was none before, which made it impossible to find all error output coming from HandleError. Keeping HandleError and HandleCrash around without deprecating while changing the signature of callbacks is a compromise between not breaking existing code and not adding too many special cases that need to be supported. There is some code which uses PanicHandlers or ErrorHandlers, but less than code that uses the Handle* calls. In Kubernetes, we want to replace the calls. logcheck warns about them in code which is supposed to be contextual. The steps towards that are: - add TODO remarks as reminder (this commit) - locally remove " TODO(pohly): " to enable the check with `//logcheck:context`, merge fixes for linter warnings - once there are none, remove the TODO to enable the check permanently |

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.
