Errors on updates are bad because they usually come from controllers and it's very hard to take actions on them. We also don't want to start breaking kubernetes clusters if something in a schema happens a way we didn't foresee (even though we've tried to be diligent and test as much as possible, these can still happen). Log an identifiable error when they happen. Ideally people can look in the logs to find these and report them, or providers can look for these in logs and make sure they don't happen. Only conversion to internal types are going to be logged and ignored. It means that we're still failing for: - Version conversions. If we can't convert the object from one version to another, - Unions. If we can't normalize the union, - Invalid MangedFields sent in the object. If something has changed the ManagedFields to an invalid value. - Failure to serialize the manager information, this really shouldn't happen. - Encoding the ManagedFields
Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts; providing basic mechanisms for 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 you are a company that 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 Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
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.
go get -d k8s.io/kubernetes
cd $GOPATH/src/k8s.io/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.
