local-up-cluster: fix instructions for set-credentials
After launching the services, local-up-cluster.sh tells the
user how to configure kubectl to access it. The instructions
for 'set-credentials' enable plain password auth, but the
services are configured to mandate client certificate auth.
As a result it is not possible to access the cluster with
the instructions printed.
The use of client certs by default was added in
commit a1b17db458
Author: Dr. Stefan Schimanski <sttts@redhat.com>
Date: Sat Nov 12 23:09:04 2016 +0100
Configure client certs in local-cluster-up.sh
and the instructions were correctly updated to refer to
client certificates.
The changed instructions were (mistakenly) reverted though
when the following commit was merged:

[Federation][kubefed] Add option to expose federation apiserver on nodeport service
**What this PR does / why we need it**:
This PR adds an option to kubefed to expose federation api server over nodeport. This can be useful to deploy federation in non-cloud environments. This PR is target to address #39271
**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**:
```
[Federation] kubefed init learned a new flag, `--api-server-service-type`, that allows service type to be specified for the federation API server.
[Federation] kubefed init also learned a new flag, `--api-server-advertise-address`, that allows specifying advertise address for federation API server in case the service type is NodePort.

Add SIG to test owners
**What this PR does / why we need it**:
This PR adds a `sig` column to the test owners file generation script.
A problem experienced with the current owners file is that since members are auto-assigned there are times where tests are assigned to non-active users who don't follow up to notifications to fix flakes. By assigning a SIG to each test we can hold a group we know is active responsible for taking care of flakes it's less likely that flakes will fall through the cracks.
**Special notes for your reviewer**:
* A companion PR will go into *kubernetes/contrib* adding support for mungers parsing this new column.
* Another PR in contrib will add labeling GitHub flake issues with the appropriate SIG
* Currently SIGs are not labeled, this will be added in another PR where SIG determinations can be discussed

Convert hack/e2e.go to a test-infra/kubetest shim
Replaces `hack/e2e.go` for a shim that passes the args to `k8s.io/test-infra/kubetest`
Adds fejta to `hack/OWNERS`
Adds `e2e_test.go` for unit test coverage of the shim.
`Usage: go run hack/e2e.go [--get=true] [--old=1d] -- KUBETEST_ARGS`
In other words there is are `--get` and `--old` shim flags, which control how we upgrade `kubetest`, and a `--` to separate the shim args from the kubetest args, and the existing kubetest args like `--down` `--up`, etc. If only `KUBETEST_ARGS` are used then you can skip the `--` (although golang will complain about it).

Local CRI node_e2e can now be performed via

make kubectl generic commands work with unstructured objects
part of making apply, edit, label, annotate, and patch work with third party resources
fixes#35149fixes#34413
prereq of:
https://github.com/kubernetes/kubernetes/issues/35496https://github.com/kubernetes/kubernetes/pull/40096
related to:
https://github.com/kubernetes/kubernetes/issues/39906https://github.com/kubernetes/kubernetes/issues/40119
kubectl is currently decoding any resource it doesn't have compiled-in to a ThirdPartyResourceData struct, which means it computes patches using that struct, and would try to send a ThirdPartyResourceData object to the API server when running `apply`
This PR removes the behavior that decodes unknown objects into ThirdPartyResourceData structs internally, and fixes up the following generic commands to work with unstructured objects
- [x] apply
- [x] decode into runtime.Unstructured objects
- [x] successfully use `--record` with unregistered objects
- [x] patch
- [x] decode into runtime.Unstructured objects
- [x] successfully use `--record` with unregistered objects
- [x] describe
- [x] decode into runtime.Unstructured objects
- [x] implement generic describer
- [x] fix other generic kubectl commands to work with unstructured objects
- [x] label
- [x] annotate
follow-ups for pre-existing issues:
- [ ] `explain` doesn't work with unregistered resources
- [ ] remove special casing of federation group in clientset lookups, etc
- [ ] `patch`
- [ ] doesn't honor output formats when persisting to server (`kubectl patch -f svc.json --type merge -p '{}' -o json` doesn't output json)
- [ ] --local throws exception (`kubectl patch -f svc.json --type merge -p '{}' --local`)
- [ ] `apply`
- [ ] fall back to generic JSON patch computation if no go struct is registered for the target GVK (e.g. https://github.com/kubernetes/kubernetes/pull/40096)
- [ ] ensure subkey deletion works in CreateThreeWayJSONMergePatch
- [ ] ensure type stomping works in CreateThreeWayJSONMergePatch
- [ ] lots of tests for generic json patch computation
- [ ] prevent generic apply patch computation among different versions
- [ ] reconcile treatment of nulls with https://github.com/kubernetes/kubernetes/pull/35496
- [ ] `edit`
- [ ] decode into runtime.Unstructured objects
- [ ] fall back to generic JSON patch computation if no go struct is registered for the target GVK

Print warning about kubelet not running on darwin via local-up-cluster.sh
**What this PR does / why we need it**: As of the time of opening this PR, near the release of v.1.5, using `./hack/local-up-cluster.sh` claims to succeed and run kubelet, but logs, processes, and attempts to hit the service demonstrate that kubelet is NOT running. The issue has been found to be the hard requirements of cadvisor forcing kubelet to force exit when it is found to be unsupported as in the case of DARWIN.
My goal here is to bring the issue to attention to others and also help other devs avoid the issue.
**Release note**:
```NONE```
kubelet.go and kubelet's server.go file has minimal logic that keeps kubelet from breaking just because osx has not cadvisor support.

Splitting master/node services into separate charm layers
**What this PR does / why we need it**:
This branch includes a roll-up series of commits from a fork of the
Kubernetes repository pre 1.5 release because we didn't make the code freeze.
This additional effort has been fully tested and has results submit into
the gubernator to enhance confidence in this code quality vs. the single
layer, posing as both master/node.
To reference the gubernator results, please see:
https://k8s-gubernator.appspot.com/builds/canonical-kubernetes-tests/logs/kubernetes-gce-e2e-node/
Apologies in advance for the large commit however, we did not want to
submit without having successful upstream automated testing results.
This commit includes:
- Support for CNI networking plugins
- Support for durable storage provided by Ceph
- Building from upstream templates (read: kubedns - no more template
drift!)
- An e2e charm-layer to make running validation tests much simpler/repeatable
- Changes to support the 1.5.x series of Kubernetes
**Special notes for your reviewer**:
Additional note: We will be targeting -all- future work against upstream
so large pull requests of this magnitude will not occur again.
**Release note**:
```release-note
- Splits Juju Charm layers into master/worker roles
- Adds support for 1.5.x series of Kubernetes
- Introduces a tactic for keeping templates in sync with upstream eliminating template drift
- Adds CNI support to the Juju Charms

- Introduces an e2e Charm layer for repeatable testing efforts and validation of clusters
