Most of the contents of docs/ has moved to kubernetes.github.io.
Development of the docs and accompanying files has continued there, making
the copies in this repo stale. I've removed everything but the .md files
which remain to redirect old links. The .yaml config files in the docs
were used by some tests, these have been moved to test/fixtures/doc-yaml,
and can remain there to be used by tests or other purposes.
Also build the hyperkube docker image on-the-fly.
This is only a temporary fix until the proposal in issue
https://github.com/kubernetes/kubernetes/issues/28630 is implemented.
Also, the new build/deployment method completely obviates this step.
We use debian image instead of busybox and do not build hyperkube as a
static binary yet. Wait until PR
https://github.com/kubernetes/kubernetes/pull/26028 is merged to build
static hyperkube binaries.

Node Conformance Test: Refactor node e2e framework
For #30122, #30174.
Based on #30348.
**Please only review the last 3 commits.**
This PR is part of our roadmap to package node conformance test.
The 1st commit is from #30348, it removed unnecessary dependencies in the node e2e test framework, because we've statically linked these dependencies.
The PR refactored the node e2e framework. Moving different utilities into different packages under `pkg/`.
We need to do this because:
1) Files like e2e_remote.go and e2e_build.go should only be used by runner, but they were compiled into the test suite because they were placed in the same package. The worst thing is that it will introduce some never used flags in the test suite binary.
2) Make the directory structure more clear. Only test should be placed in `test/e2e_node`, other utilities should be placed in different packages in `pkg/`.

Explicitly set CLOUDSDK_CONFIG override early in e2e-runner
I'm guessing this is why a number of gci-on-gke builds started failing after https://github.com/kubernetes/test-infra/pull/432 was merged - we're overriding the gcloud configuration location from the default, so the activated service account no longer works. Previously we did this service activation late, but after we'd overridden the value.
I've changed it to explicitly set to a known-good value every time at the very start.

Add admission controller for default storage class.
The admission controller adds a default class to PVCs that do not require any
specific class. This way, users (=PVC authors) do not need to care about
storage classes, administrator can configure a default one and all these PVCs
that do not care about class will get the default one.
The marker of default class is annotation "volume.beta.kubernetes.io/storage-class", which must be set to "true" to work. All other values (or missing annotation) makes the class non-default.
Based on @thockin's code, added tests and made it not to reject a PVC when no class is marked as default.

AppArmor PodSecurityPolicy support
Implements the AppArmor PodSecurityPolicy support based on the alpha API proposed [here](https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/apparmor.md#pod-security-policy)
This implementation deviates from the original proposal in one way: it adds a separate option for specifying a default profile:
```
apparmor.security.alpha.kubernetes.io/defaultProfileName
```
This has several advantages over the original proposal:
- The default is explicit, rather than implicit on the ordering
- The default can be specified without constraining the allowed profiles
- The allowed profiles can be restricted without specifying a default (requires every pod to explicitly set a profile)
The E2E cluster does not currently enable the PodSecurityPolicy, so I will submit E2E tests in a separate PR.
/cc @dchen1107 @pweil- @sttts @jfrazelle @Amey-D
MTU selection is difficult, and if there is a transport such as IPSEC in
use may be impossible. So we allow specification of the MTU with the
network-plugin-mtu flag, and we pass this down into the network
provider.
Currently implemented by kubenet.

Fix caching of go dirs during build
Sometimes when you press `^C` during `make` the subsequent attempt to run `make` hangs due to zero-sized cache file for `ALL_GO_DIRS` var in Makefile.generated_files:

e2e-runner: Get GCI builtin k8s version from GCS
**What this PR does / why we need it**:
The GCI release qualification tests use builtin k8s version to run tests. They used to get the builtin version by parsing descriptions of the test images, but that's unreliable because the description format could change. This PR makes it to read a file checked in GCS that has the exact k8s version number.

In validating etcd.v3client we had uncovered that a change in the behavior of the client https://github.com/coreos/etcd/issues/6162 , caused a number of unit tests to fail. These test failures were due to the fact that the unit tests were trying to standup a apiserver even though there was no etcd backend stood up.

@lukemarsden @mikedanese
```release-note
The Kubelet now supports the `--force-kubeconfig` option which reads all client config from the provided `--kubeconfig` file and will cause the Kubelet to exit with error code 1 on error. It also forces the Kubelet to use the server URL from the kubeconfig file rather than the `--api-servers` flag. Without this flag set, a failure to read the kubeconfig file would only result in a warning message.
In a future release, the value of this flag will be defaulted to `true`.

Fix subtle build breakage
Repro case:
$ make clean generated_files
$ hack/update-generated-protobuf.sh
This would complain about not finding `fmt`, and it was indicating the wrong
GOROOT. The problem was that the first step built binaries for generating
code, which *embeds* the value of GOROOT into the binary. The whole tree was
bind-mounted into the build container and then JUST the dockerized dir was
mounted over it. The in-container build tried to use the existing binaries,
but GOROOT is wrong.
This change whites-out the whole _output dir.
I first made just an anonymous volume for _output, but docker makes that as
root, which means I can't write to it from our non-root build. So I just put
it in the data container. This seems to work. The biggest change this makes
is that the $GOPATH/bin/ and $GOPATH/pkg/ dirs will persist across dockerized
builds.

Add CloudStack cloud provider (extended and refactored)
This PR is superseding PR #26165 is which some groundwork for this PR has been done. So this PR now fixes#26165 and fixes#26045.
I've been in contact with @ngtuna about this updated version of his earlier work (which is still in this PR as one squashed commit) and he has given his 👍 for this 😉
This PR adds additional logic for allocating and associating a public IP, if the `—load-balancer-ip` option is not used. It will do proper management of public IP’s that are allocated by this provider ( so IP’s that are no longer needed/used will also be released again).
Additionally the provider can now also work with CloudStack projects and advanced (VPC) networks. And lastly the Zone interface now returns an actual zone (supplied by the cloud config), a few logical errors are fixed and the first few tests are added.
All the functionality is extensively tested against both basic and advanced (VPC) networks and of course all new and existing (integration) tests are all passing.

Added `golint` for pkg/security/podsecuritypolicy/capabilities` along with validation.
```
[]()
This is a POC to start enabling `golint` checks on a per-package basis, we did this on the docker project and it was a great way for new contributors to help and it benefits the project overall. All they have to do is add the package they fixed to the bash array in `hack/verify-golint.sh` and fix all the lint errors.
Eventually when all the packages have been fixed we can change the function to `find_files`. Or something based off which files are changed in a patch set to verify `golint`.
Now I used this specific package as the POC because I wanted to show the downside of this changing the api of the package.
Most of the times this arose in docker/docker we decided that if someone wasn't importing their deps locally then it was their loss, but I'm not sure if you all will agree.

Cut the client repo, staging it in the main repo
Tracking issue: #28559
ref: https://github.com/kubernetes/kubernetes/pull/25978#issuecomment-232710174
This PR implements the plan a few of us came up with last week for cutting client into its own repo:
1. creating "_staging" (name is tentative) directory in the main repo, using a script to copy the client and its dependencies to this directory
2. periodically publishing the contents of this staging client to k8s.io/client-go repo
3. converting k8s components in the main repo to use the staged client. They should import the staged client as if the client were vendored. (i.e., the import line should be `import "k8s.io/client-go/<pacakge name>`). This requirement is to ease step 4.
4. In the future, removing the staging area, and vendoring the real client-go repo.
The advantage of having the staging area is that we can continuously run integration/e2e tests with the latest client repo and the latest main repo, without waiting for the client repo to be vendored back into the main repo. This staging area will exist until our test matrix is vendoring both the client and the server.
In the above plan, the tricky part is step 3. This PR achieves it by creating a symlink under ./vendor, pointing to the staging area, so packages in the main repo can refer to the client repo as if it's vendored. To prevent the godep tool from messing up the staging area, we export the staged client to GOPATH in hack/godep-save.sh so godep will think the client packages are local and won't attempt to manage ./vendor/k8s.io/client-go.
This is a POC. We'll rearrange the directory layout of the client before merge.

The Kubelet process must have CAP_SYS_ADMIN, which implies that
the kubelet process must be either running as root or in a privileged
container. Make this check early in the startup sequence and bail out
if necessary.

kubectl config set-crentials: add arguments for auth providers
This PR adds `--auth-provider` and `--auth-provider-arg` flags to the
`kubectl config set-credentials` sub-command.
There's currently no way of interacting with the new auth provider framework added in #23066 through kubectl. You have to render a custom kubeconfig to use them. Additionally `kubectl config set` just sort of craps out when attempting to interact with authentication info objects (#29312).
This is a minimal implementation of allowing `kubect config set-credentials` to set fields for client auth providers.

Cleanup k8s script noise with a verbosity concept
Fixes https://github.com/kubernetes/kubernetes/issues/30109
The KUBE_VERBOSE environment variable sets the verbosity level to
use. Log messages can specify a verbosity by setting the V
variable. e.g.
V=2 kube::log::info foo bar
Would only print "foo bar" if $KUBE_VERBOSE >= 2.
Examples:
Default verbosity (1 for make commands):
```

Install go-bindata in cross-build image
Another follow-up to #25584.
We need `go-bindata` to create `test/e2e/generated`, and downloading it with `go get` at build time is painful for a variety of reasons. We can just include it in the cross-build image and not worry about it, especially as it updates very infrequently.
This fixes `hack/update-generated-protobuf.sh` as well.
