Automatic merge from submit-queue (batch tested with PRs 50381, 51307, 49645, 50995, 51523) Bugfix: Use local JSON log buffer in parseDockerJSONLog. **What this PR does / why we need it**: The issue described in #47800 is due to a race condition in `ReadLogs`: Because the JSON log buffer (`dockerJSONLog`) is package-scoped, any two goroutines modifying the buffer could race and overwrite the other's changes. In particular, one goroutine could unmarshal a JSON log line into the buffer, then another goroutine could `Reset()` the buffer, and the resulting `Stream` would be empty (`""`). This empty `Stream` is caught in a `case` block and raises an `unexpected stream type` error. This PR creates a new buffer for each execution of `parseDockerJSONLog`, so each goroutine is guaranteed to have a local instance of the buffer. **Which issue this PR fixes**: fixes #47800 **Release note**: ```release-note Fixed an issue (#47800) where `kubectl logs -f` failed with `unexpected stream type ""`. ``` |

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
If you are less impatient, 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.
