In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
If You Care About the Process:
------------------------------
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
Also, see https://github.com/kubernetes/contrib/issues/1389.
TLDR:
-----
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.
2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the future in
the **reviewers** section. You probably do NOT need to modify the **approvers**
section. Names asre sorted by relevance, using some secret statistics.
3. Notify me if you want some OWNERS file to be removed. Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.
4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

Remove json serialization annotations from internal types
fixes#3933
Internal types should never be serialized, and including json serialization tags on them makes it possible to accidentally do that without realizing it.
fixes in this PR:
* types
* [x] remove json tags from internal types
* [x] fix references from serialized types to internal ObjectMeta
* generation
* [x] remove generated json codecs for internal types (they should never be used)
* kubectl
* [x] fix `apply` to operate on versioned object
* [x] fix sorting by field to operate on versioned object
* [x] fix `--record` to build annotation patch using versioned object
* hpa
* [x] fix unmarshaling to internal CustomMetricTargetList in validation
* thirdpartyresources
* [x] fix encoding API responses using internal ObjectMeta
* tests
* [x] fix tests to use versioned objects when checking encoded content
* [x] fix tests passing internal objects to generic printers
follow ups (will open tracking issues or additional PRs):
- [ ] remove json tags from internal kubeconfig types (`kubectl config set` pathfinding needs to work against external type)
- [ ] HPA should version CustomMetricTargetList serialization in annotations
- [ ] revisit how TPR resthandlers encoding objects
- [ ] audit and add tests for printer use (human-readable printer requires internal versions, generic printers require external versions)
- [ ] add static analysis tests preventing new internal types from adding tags
- [ ] add static analysis tests requiring json tags on external types (and enforcing lower-case first letter)
- [ ] add more tests for `kubectl get` exercising known and unknown types with all output options

kubeadm UX improvements for the v1.5 stable release
This PR targets the next stable kubeadm release.
It's work in progress, but please comment on it and review, since there are many changes.
I tried to group the commits logically, so you can review them separately.
Q: Why this large PR? Why not many small?
A: Because of the Submit Queue and the time it takes.
PTAL @kubernetes/sig-cluster-lifecycle

Add GetOptions parameter to Get() calls in client library
Ref #37473
This PR is super mechanical - the non trivial commits are:
- Update client generator
- Register GetOptions in batch/v2alpha1 group
Fix boilerplates, comments in the code and make the output of kubeadm more user-friendly
Start using HostPKIPath and KubernetesDir everywhere in the code, so they can be changed for real
More robust kubeadm reset code now.
Removed old glog-things from app.Run()
Renamed /etc/kubernetes/cloud-config.json to /etc/kubernetes/cloud-config since it shouldn't be a json file
Simplification of the code
Less verbose output from master/pki.go
Cleaned up dead code
Start a small logging/output framework:
- fmt.Println("[the-stage-here] Capital first letter of this message. Tell the user what the current state is")
- fmt.Printf("[the-stage-here] Capital first letter. Maybe a [%v] in the end if an error should be displayed. Always ends with \n")
- fmt.Errorf("Never starts with []. Includes a short error message plus the underlying error in [%v]. Never ends with \n")

Add a cloudprovider validator flag to kubeadm and update the DNS spec
Broken out from: https://github.com/kubernetes/kubernetes/pull/37568
This PR creates a flag for `cloud-provider` that validates the value before `RunInit()` is run, which makes it now act as a "real" flag
Then it removes the `k8s.io/kubernetes/pkg/cloudprovider` dependency, which makes the binary ~40MB smaller! That's _really_ worth it!
In the second commit, the DNS addon is updated to the latest version: https://github.com/kubernetes/kubernetes/blob/master/cluster/addons/dns/skydns-rc.yaml.base

Revert "[kubeadm] use iteration instead of recursion in function"
Reverts kubernetes/kubernetes#36625
Removing the recursive call means that `n` is never updated, so you never succeed in the update, and you've creating an infinite loop.
Also, this entire bit of functionality should be a patch and you won't have to worry about conflicts.

kubeadm: Implement support for symbolic labels in --use-kubernetes-version
**What this PR does / why we need it**: This patch adds "stable", "latest" and other labels as valid versions in "kubeadm init --use-kubernetes-version" flag.
Now, defaults can be pointing to "stable" and users will always get
latest available stable build of Kubernetes via kubeadm.
There is no need anymore to hardcode version string inside kubeadm
binary.
It is also possible to use labels like "latest" or point to exact
branch: "stable-1.4"
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
**Release note**:
```release-note
- kubeadm init --use-kubernetes-version now understands "stable","latest", "stable-1.4" and other labels as valid version. It will fetch actual build number from release servers.
```
