Tristan Burgess bcdf3bb643 50342: Establish '406 Not Acceptable' response for protobuf serialization 'errNotMarshalable'
- 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

Submit Queue Widget GoDoc Widget CII Best Practices


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.
