Automatic merge from submit-queue (batch tested with PRs 58903, 58141, 58900). 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>. auth/gcp: configurable scopes for gcp default credentials **What this PR does / why we need it**: - add `config.scopes` field comma-separated scope URLs, to be used with Google Application Default Credentials (i.e. GOOGLE_APPLICATION_CREDENTIALS env) - users now should be able to set a gserviceaccount key in GOOGLE_APPLICATION_CREDENTIALS env, craft a kubeconfig file with GKE master IP+CA cert and should be able to authenticate to GKE in headless mode _without requiring gcloud_ CLI, and they can now use the email address of the gserviceaccount in RBAC role bindings and _not use Google Cloud IAM at all._ - gcp default scopes now include userinfo.email scope, so authenticating to GKE using gserviceaccount keys can now be done without gcloud as well. - since userinfo.email scope is now a default, users who have existing RBAC bindings that use numeric uniqueID of the gserviceaccount will be broken (this behavior was never documented/guaranteed). from now on email address of the service account should be used as the subject in RBAC Role Bindings. **Release note**: ```release-note Google Cloud Service Account email addresses can now be used in RBAC Role bindings since the default scopes now include the "userinfo.email" scope. This is a breaking change if the numeric uniqueIDs of the Google service accounts were being used in RBAC role bindings. The behavior can be overridden by explicitly specifying the scope values as comma-separated string in the "users[*].config.scopes" field in the KUBECONFIG file. ``` /assign @cjcullen /sig gcp
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.
