[GCE] Set --kubelet-preferred-address-types on apiserver by default **What this PR does / why we need it**: We currently set the default value of `PreferredAddressTypes` in `KubeletConfig` for apiserver as below:2f403b7ad1/cmd/kube-apiserver/app/options/options.go (L99-L110)It denotes the ways (order matters) we prefer to use for kubelet connections, in which `NodeHostName` is listed as the most preferred one. However, it is not safe to assume `NodeHostName` will always be resolvable. This PR makes `InternalIP` as the most preferred one instead. Note that this doesn't affect how the ssh tunnel is setup, which is configured explicitly elsewhere:d0d1e1dcc4/pkg/master/master.go (L442-L445)d0d1e1dcc4/pkg/master/master.go (L388-L389)**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes #NONE **Special notes for your reviewer**: /assign @bowei @cjcullen cc @dnardo in case I made terrible mistakes. **Release note**: ```release-note NONE ```
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.
