Instead we currently do that validation in preflight checks, which is in the totally wrong place. - Now that we pull images in preflight checks, the timeout for the kubelet to start the Static Pods should be kinda short, as it doesn't depend on internet connection - I think the shorthand for `kubeadm reset --force` ought to be `-f` - The common flags between `upgrade apply` and `upgrade plan` were registered as global flags for the `upgrade` command, although they make no sense for `upgrade diff` and/or `upgrade node config`. Hence, I moved them to be locally registered. - Just because we vendor `glog` we have a lot of unnecessary/annoying flags registered in glog's `init()` function. Let's hide these properly. - I saw that `kubeadm upgrade apply` doesn't write down the new kubelet config that should be used, now that is the case. Also, the CRISocket annotation information is now preserved properly on upgrade (and is configurable using the `--cri-socket` flag) - If `kubeadm join` is run against a v1.10 cluster without the `kubelet-config-1.10` configmap, it shouldn't fail. What I will still investigate: - `kubeadm token create` should have a flag called `--ttl`, not `--token-ttl` as it is now (this snuck in in this dev cycle) - That `--dry-run` works properly for `upgrade`, end to end. **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 # **Special notes for your reviewer**: **Release note**: ```release-note NONE ``` @kubernetes/sig-cluster-lifecycle-pr-reviews |

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.
