- Added metav1.Status() that enforces '406 Not Acceptable' response if protobuf serialization is not fully supported for the API resource type. - JSON and YAML serialization are supposed to be more completely baked in, so serialization involving those, and general errors with seralizing protobuf, will return '500 Internal Server Error'. - If serialization failure occurs and original HTTP status code is error, use the original status code, else use the serialization failure status code. - Write encoded API responses to intermediate buffer - Use apimachinery/runtime::Encode() instead of apimachinery/runtime/protocol::Encode() in apiserver/endpoints/handlers/responsewriters/writers::SerializeObject() - This allows for intended encoder error handling to fully work, facilitated by apiserver/endpoints/handlers/responsewriters/status::ErrorToAPIResponse() before officially writing to the http.ResponseWriter - The specific part that wasn't working by ErrorToAPIResponse() was the HTTP status code set. A direct call to http.ResponseWriter::WriteHeader(statusCode) was made in SerializeObject() with the original response status code, before performing the encode. Once this method is called, it can not again update the status code at a later time, with say, an erro status code due to encode failure. - Updated relevant apiserver unit test to reflect the new behavior (TestWriteJSONDecodeError()) - Add build deps from make update for protobuf serializer 50342: Code review suggestion impl - Ensure that http.ResponseWriter::Header().Set() is called before http.ResponseWriter::WriteHeader() - This will avert a potential issue where changing the response media type to text/plain wouldn't work. - We want to respond with plain text if serialization fails of the original response, and serialization also fails for the resultant error response. 50342: wrapper for http.ResponseWriter - Prevent potential performance regression caused by modifying encode to use a buffer instead of streaming - This is achieved by creating a wrapper type for http.ResponseWriter that will use WriteHeader(statusCode) on the first call to Write(). Thus, on encode success, Write() will write the original statusCode. On encode failure, we pass control onto responsewriters::errSerializationFatal(), which will process the error to obtain potentially a new status code, depending on whether or not the original status code was itself an error. 50342: code review suggestions - Remove historical note from unit test comment - Don't export httpResponseWriterWithInit type (for now) |

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.
