We want to continuously validate Docker releases (#25215), on GCI. This change
adds a new test config variable, `KUBE_GCI_DOCKER_VERSION`, through which we can
specify which version of Docker we want to run on the master and nodes. This
change also patches the Jenkins e2e-runner with the ability to fetch the latest
Docker (pre)release, and sets the aforementioned variable accordingly.

Attach/Detach Controller Kubelet Changes
This PR contains changes to enable attach/detach controller proposed in #20262.
Specifically it:
* Introduces a new `enable-controller-attach-detach` kubelet flag to enable control by attach/detach controller. Default enabled.
* Removes all references `SafeToDetach` annotation from controller.
* Adds the new `VolumesInUse` field to the Node Status API object.
* Modifies the controller to use `VolumesInUse` instead of `SafeToDetach` annotation to gate detachment.
* Modifies kubelet to set `VolumesInUse` before Mount and after Unmount.
* There is a bug in the `node-problem-detector` binary that causes `VolumesInUse` to get reset to nil every 30 seconds. Issue https://github.com/kubernetes/node-problem-detector/issues/9#issuecomment-221770924 opened to fix that.
* There is a bug here in the mount/unmount code that prevents resetting `VolumeInUse in some cases, this will be fixed by mount/unmount refactor.
* Have controller process detaches before attaches so that volumes referenced by pods that are rescheduled to a different node are detached first.
* Fix misc bugs in controller.
* Modify GCE attacher to: remove retries, remove mutex, and not fail if volume is already attached or already detached.
Fixes#14642, #19953
```release-note
Kubernetes v1.3 introduces a new Attach/Detach Controller. This controller manages attaching and detaching volumes on-behalf of nodes that have the "volumes.kubernetes.io/controller-managed-attach-detach" annotation.
A kubelet flag, "enable-controller-attach-detach" (default true), controls whether a node sets the "controller-managed-attach-detach" or not.

Fixes#26526 - hack/update-api-reference-docs.sh
I opened a Pull request to fix this issue https://github.com/kubernetes/kubernetes/issues/26526
The problem is that the update script ignores white spaces but the verify script doesn't which leads to a strange behaviour -> you use the update script but the verify script tells you that the api docs are not up to date.

Add it as a special case package root and import the license file. This was
the only UNKNOWN license, prior to the change to not look at upstream repo
state.
This change recovers some of the side effects of
https://github.com/kubernetes/kubernetes/pull/26197, i.e., keeps the defaults of
`NODE_IMAGE` and `NODE_IMAGE_PROJECT` to `MASTER_IMAGE` and
`MASTER_IMAGE_PROJECT`, for backward compatibility. Although it keeps
`OS_DISTRIBUTION` defaulting to `gci`, the default settings of these vars are
moved to `cluster/gce/util.sh` and conditioned on `OS_DISTRIBUTION==gci`.

Don't set the env var CC when not cross-compiling
I noticed that this script was trying to use `arm-linux-gnueabi-gcc` also when running natively on arm.
When running natively, `CC` should always be `gcc` (which also is the default)
Also added `federation-controller-manager` to the static list, I think someone forgot to do that.

kube-controller-manager: Add configure-cloud-routes option
This allows kube-controller-manager to allocate CIDRs to nodes (with
allocate-node-cidrs=true), but will not try to configure them on the
cloud provider, even if the cloud provider supports Routes.
The default is configure-cloud-routes=true, and it will only try to
configure routes if allocate-node-cidrs is also configured, so the
default behaviour is unchanged.
This is useful because on AWS the cloud provider configures routes by
setting up VPC routing table entries, but there is a limit of 50
entries. So setting configure-cloud-routes on AWS would allow us to
continue to allocate node CIDRs as today, but replace the VPC
route-table mechanism with something not limited to 50 nodes.
We can't just turn off the cloud-provider entirely because it also
controls other things - node discovery, load balancer creation etc.

Push public key to project if not already present
Fixes https://github.com/kubernetes/kubernetes/issues/26128
Fixes https://github.com/kubernetes/kubernetes/issues/26129
Whenever the ssh key changes (which happens right now whenever we add/change a new jenkins agent) this key will not get pushed to the project until either `gcloud compute ssh` or `gcloud compute config-ssh` runs. As a result instances on this project will reject ssh attempts with this key.
In many cases this will not happen until after a test on a project fails and we attempt to ssh to the nodes to grab logs.
This verifies the presence of the ssh key before starting tests, and attempts to add it if it is missing.
Jenkins relies on junit.xml to identify test failures
and non-0 exit codes to indentify infrastructure failures.
Test failures in kubemark tests should not cause the test
script to exit non-0. Infrastructure failures should.
- Add function to dump cluster logs without exiting (refactor)
- Change `test/kubemark/stop-kubemark.sh` to be run regardless of whether tests fail or not
- Exit code for failed tests overwritten to be the exit code of dumping the cluster logs
This code used to actually reach out to the internet to look for files. This
is flaky, slow, and semantically WRONG. The license that is upstream might
actually be different than what we have vendored. Only look at local files.
This now passes back-to-back updates and verifies.

allocate-node-cidrs=true), but will not try to configure them on the

Improve the speed of do-nothing build.
As @thockin found out here https://github.com/kubernetes/kubernetes/issues/24518, vast majority of the do-nothing build time is spent in rebuilding the test binaries. There is no staleness check support for test binaries.
This commit implements the staleness checks for test binaries and uses them while building packages.
On my workstation, do-nothing hack/build-go.sh time goes from ~20 secs to ~4 secs, of which only ~1 sec is from doing test binary staleness check now (as opposed to ~17 secs it took to build the test binaries before). I did some experiments to bring this time down to <1 sec. I measured using go test -bench, but it was not very useful in this case. I believe, a vast majority of that ~1 second is being spent in fork/exec and piping the results back to the staleness check program along with the ser-deser involved, but it needs to be validated. Not a proof, but to provide some supporting evidence to this claim, running `go list -f format packages` in the shell takes about 600ms irrespective of what's in the format.
Tests are TBD. I am still trying to figure out how to test this, but I would like to get early feedback

Quality of Service will be derived from an entire Pod Spec, instead of being derived from resource specifications of individual resources per-container.

A Pod is `BestEffort` iff requests & limits are not specified for any resource across all containers.
A Pod is `Burstable` otherwise.
Note: Existing pods might be more susceptible to OOM Kills on the node due to this PR! To protect pods from being OOM killed on the node, set `limits` for all resources across all containers in a pod.

Add 'kubectl set image'
```release-note
Add "kubectl set image" for easier updating container images (for pods or resources with pod templates).
```
**Usage:**
```
kubectl set image (-f FILENAME | TYPE NAME) CONTAINER_NAME_1=CONTAINER_IMAGE_1 ... CONTAINER_NAME_N=CONTAINER_IMAGE_N
```
**Example:**
```console
# Set a deployment's nginx container image to 'nginx:1.9.1', and its busybox container image to 'busybox'.
$ kubectl set image deployment/nginx busybox=busybox nginx=nginx:1.9.1
# Update all deployments' nginx container's image to 'nginx:1.9.1'
$ kubectl set image deployments nginx=nginx:1.9.1 --all
# Update image of all containers of daemonset abc to 'nginx:1.9.1'
$ kubectl set image daemonset abc *=nginx:1.9.1
# Print result (in yaml format) of updating nginx container image from local file, without hitting the server
$ kubectl set image -f path/to/file.yaml nginx=nginx:1.9.1 --local -o yaml
```
I abandoned the `--container=xxx --image=xxx` flags in the [deploy proposal](https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/deploy.md#kubectl-set) since it's much easier to use with just KEY=VALUE (CONTAINER_NAME=CONTAINER_IMAGE) pairs.

Adding Services to federation clientset
Commits:
1. Regenerate the client without any changes to client-gen
2. Update clientgen to add a parameter to specify generating client only for Services v1 object.
3. Regenerate federation_internalclientset
4. Regenerate federation_release_1_3
Second commit is the most important one. Other 3 commits are auto generated by running client-gen.
I have added a command line argument to client-gen that takes in a list of group/version/resource. If a group version is part of this list, then only the resources in this list are included in the client. For other group versions, the existing check of genclient=true in types.go is used.
Other alternatives considered were:
* Update genclient in types.go to mention the clientset name in which it should be included instead of just saying genclient=true (so Services will say genclient=core,federation while all other v1 resources will say genclient=core). This requires a code change in types.go to change a client set.
* Create another types.go which will only include Services and use that to generate federation clientset. This will lead to duplicate Service definition.

pkg/apis/rbac: Add Openshift authorization API types
This PR updates #23396 by adding the Openshift RBAC types to a new API group.
Changes from Openshift:
* Omission of [ResourceGroups](4589987883/pkg/authorization/api/types.go (L32-L104)) as most of these were Openshift specific. Would like to add the concept back in for a later release of the API.
* Omission of IsPersonalSubjectAccessReview as its implementation relied on Openshift capability.
* Omission of SubjectAccessReview and ResourceAccessReview types. These are defined in `authorization.k8s.io`
~~API group is named `rbac.authorization.openshift.com` as we omitted the AccessReview stuff and that seemed to be the lest controversial based on conversations in #23396. Would be happy to change it if there's a dislike for the name.~~ Edit: API groups is named `rbac`, sorry misread the original thread.
As discussed in #18762, creating a new API group is kind difficult right now and the documentation is very out of date. Got a little help from @soltysh but I'm sure I'm missing some things. Also still need to add validation and a RESTStorage registry interface. Hence "WIP".

cluster/images/hyperkube: create symlink for each server
Add a kubelet symlink so that the hyperkube image can appear as a kubelet image. https://github.com/kubernetes/kubernetes/issues/24510
a) it doesn't need it
b) changing CWD to a path with symlinks breaks deep within ginkgo, where it
crafts a relative path to ../../../../../../platforms/amd64/whatever which then
traverses the physical path not the symlinked one, and breaks.
Our `realpath` and `readlink -f` functions (required only because of MacOS,
thanks Steve) were poor substitutes at best. Mostly they were downright
broken. This thoroughly overhauls them and adds a test (in comments, since we
don't seem to have shell tests). For all the interesting cases I could think
of, the fakes act just like the real thing.
Then use those and canonicalize KUBE_ROOT. In order to make recursive calls of
our shell tool not additively grow `pwd` we have to essentially make the
sourcing of init.sh idempotent.

For instance, a user can now use a single PersistentVolume to store the Mysql database and the document root of an Apache server of a LAMP stack pod by mapping them to different subPaths in this single volume.

Allow etcd to store protobuf objects
Split storage serialization from client negotiation, and allow API server to take flag controlling serialization.
TODO:
* [x] API server still doesn't start - range allocation object doesn't seem to round trip correctly to etcd
* [ ] Verify that third party resources are ignoring protobuf (add a test)
* [ ] Add integration tests that verify storage is correctly protobuf
* [ ] Add a global default for which storage format to prefer?

Map secret files into dockerized e2e
Rather than copying the GCE and AWS private keys/credentials to each Jenkins VM, we can put them in credentials and map them through.
This is one half of the change; if the relevant environment variables are set, we'll mount the files in.

The codec factory should support two distinct interfaces - negotiating
for a serializer with a client, vs reading or writing data to a storage
form (etcd, disk, etc). Make the EncodeForVersion and DecodeToVersion
methods only take Encoder and Decoder, and slight refactoring elsewhere.
In the storage factory, use a content type to control what serializer to
pick, and use the universal deserializer. This ensures that storage can
read JSON (which might be from older objects) while only writing
protobuf. Add exceptions for those resources that may not be able to
write to protobuf (specifically third party resources, but potentially
others in the future).
