Automatic merge from submit-queue (batch tested with PRs 56115, 55143, 56179). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>.
Do not add new field in fluentd CRI log format.
After https://github.com/kubernetes/kubernetes/pull/55922 is merged, the test `Cluster level logging implemented by Stackdriver should ingest logs` starts to fail in cri-containerd cluster e2e test.
https://k8s-testgrid.appspot.com/sig-node-containerd#e2e-gci
I believe the reason is that the GCP fluentd plugin assumes that there are only `timestamp`, `severity`, `stream` and `log|message|msg` fields in the log entry.
If there is any other fields, GCP fluentd plugin will not try to convert the payload to json, even if the log content is json. The plugin deletes `stream`, `timestamp` and `severity`, then assumes that there is only one field left

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.
