pass the kubelet flags through a new variable in kube-env
(KUBELET_ARGS).
Remove vars from kube-env that were only used for kubelet flags.
This will make it simpler to gradually migrate to dynamic kubelet
config, because we can gradually replace flags with config file
options in a single place without worrying about the plumbing to
move variables from the client onto the node.

Add code and yaml for Istio as an addon
This commit adds the following:
- YAML for istio components to the addons directory (versions with
and without auth)
- logic to copy the appropriate YAML file into the addons manager
dir, depending on ENABLE_ISTIO and ISTIO_AUTH_TYPE env vars
- changes to addon manager script which allow plugins to exist in
namespace other than kube-system. This is needed for Istio
functionality
- additional initialization for Istio in addon manager.
This has been manually tested - e2e tests are in progress but require additional code to enable istio in tests. See:

Add etcd 3.x minor version rollback support to migrate-if-needed.sh
Provide automatic etcd 3.x minor version downgrade when using the gcr.io/google_containers/etcd docker images to operate etcd.
Uses `etcdctl snapshot save` and `etcdctl snapshot restore` to safely downgrade etcd from 3.2->3.1 or 3.1->3.0. This is safe because the data storage file formats used by etcd have not changed between these versions.
Intended as a stop-gap until we can introduce more comprehensive downgrade support in etcd. The main limitation of this approach is that it is not able to perform zero downtime downgrades for HA clusters. For HA clusters, all members must be stopped and downgraded before the cluster may be restarted at the downgraded version.
Example usage:
- Initially the [etcd.manifest](58547ebd72/cluster/gce/manifests/etcd.manifest (L43)) is set to gcr.io/google_containers/etcd:3.0.17, TARGET_VERSION=3.0.17
- A upgrade to 3.1.11 is initiated.
- etcd.manifest is updated to gcr.io/google_containers/etcd:3.1.11, TARGET_VERSION=3.1.11
- etcd restarts and establishes 3.1 as it's "cluster version"
- For whatever reason, a downgrade is initiated
- etcd.manifest is updated gcr.io/google_containers/etcd:3.1.11, TARGET_VERSION=3.0.17
- migrate-if-needed.sh detects that the current version (3.1.11) is newer than the target version, so it:
- creates a snapshot using etcd & etcdctl 3.1.11
- backs up the data dir
- restores the snapshot using etcdctl 3.0.17 to create a replacement data dir
- starts etcd 3.0.17
Note that while this will rollback to an earlier etcd version, the newer etcd gcr.io image version must continue to be used throughout the downgrade. Only TARGET_VERSION is downgraded.
Test coverage was lacking for `migrate-if-needed.sh` so this adds some container level testing to the `Makefile` for migrating and rolling back. This surfaced a couple bugs that are fixed by this PR as well.

2nd try at using a vanity GCR name
The 2nd commit here is the changes relative to the reverted PR. Please focus review attention on that.
This is the 2nd attempt. The previous try (#57573) was reverted while we
figured out the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.
xref https://github.com/kubernetes/release/issues/281
TL;DR:
* The new `staging-k8s.gcr.io` is where we push images. It is literally an alias to `gcr.io/google_containers` (the existing repo) and is hosted in the US.
* The contents of `staging-k8s.gcr.io` are automatically synced to `{asia,eu,us)-k8s.gcr.io`.
* The new `k8s.gcr.io` will be a read-only alias to whichever regional repo is closest to you.
* In the future, images will be promoted from `staging` to regional "prod" more explicitly and auditably.
```release-note
Use "k8s.gcr.io" for pulling container images rather than "gcr.io/google_containers". Images are already synced, so this should not impact anyone materially.
Documentation and tools should all convert to the new name. Users should take note of this in case they see this new name in the system.
```

Make kubelet flags of kube-up.sh configurable.
Fixes https://github.com/kubernetes/kubernetes/issues/59503.
For CRI container runtime, we need to pass kubelet the container runtime cgroup.
~~Currently, for `e2e-up.sh` we can use `KUBE_TEST_ARGS` to configure kubelet flags. However, for `kube-up.sh` we don't have a way to configure it.~~
Actually we can also use `KUBE_TEST_ARGS` for kubelet flags. However, I prefer we still make this change to make the env name more formalized.

and another to request a daemon restart (if needed).
- run docker login after any potential daemon restarts have occurred.

Ensure that the runtime mounts RO volumes read-only
**What this PR does / why we need it**:
This change makes it so that containers cannot write to secret, configMap, downwardAPI and projected volumes since the runtime will now mount them read-only. This change makes things less confusing for a user since any attempt to update a secret volume will result in an error rather than a successful change followed by a revert by the kubelet when the volume next syncs.
It also adds a feature gate `ReadOnlyAPIDataVolumes` to a provide a way to disable the new behavior in 1.10, but for 1.11, the new behavior will become non-optional.
Also, E2E tests for downwardAPI and projected volumes are updated to mount the volumes somewhere other than /etc.
**Which issue(s) this PR fixes**
Fixes#58719
**Release note**:
```release-note
Containers now mount secret, configMap, downwardAPI and projected volumes read-only. Previously,
container modifications to files in these types of volumes were temporary and reverted by the kubelet
during volume sync. Until version 1.11, setting the feature gate ReadOnlyAPIDataVolumes=false will
preserve the old behavior.

Fix master regex when running multiple clusters
**What this PR does / why we need it**:
I'm running two Kubernetes clusters on GCE. One for production and one for staging. The instance prefix I use for production is `kubernetes` and for staging it's `staging-kubernetes`. This caused a problem when running `kube-up.sh` for production because when it tries to find all instances which match `kubernetes(-...)?` it finds both the production and staging instances. This probably results in multiple problems, but the most noticeable one for me was that `INITIAL_ETCD_CLUSTER` was incorrect and so etcd wouldn't start up correctly so the api server doesn't start up correctly so nothing else starts up. I tested this manually and it seems to work for me, but I didn't write an automated test.

Honor make variable OUT_DIR in hyperkube Makefile
Needed to ensure the split of `make cross-in-a-container` and `make package-tarballs` honors the use of `OUT_DIR`.
In the new and upcoming containerized (GCB) release builds, multiple `cross-in-a-container` targets are run into their own `_output ($OUT_DIR)` directories and a second pass runs multiple `package-tarballs`.
This won't work unless we honor `$OUT_DIR` here.

Improve etcd-version-monitor metrics proxying, add etcd 3.1 gprc metr…
Partially addresses https://github.com/kubernetes/kubernetes/issues/56869:
- Fix `etcd-version-monitor` to support etcd 3.1: Add support for the etcd 3.1+ [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus) metrics format, which backward incompatibly replaces the 3.0 legacy grpc metric format. Expose the go-grpc-prometheus metrics both in the 3.1 format and in the 3.0 format so systems consuming `etcd-version-monitor` metrics have a clean, simple upgrade path.
- Expose *all* etcd metrics by default, making this a one stop shop for all etcd metrics.
- Expose grpc request latency histogram metrics (`grpc_server_handling_seconds` from [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus) metrics format). Rewrite etcd 3.0 legacy metric for latency histograms to the etcd 3.1+ `go-grpc-prometheus` format so there is a single format exported for all etcd versions.
etcd 3.0 to 3.1 upgrade path: Continue to use the `etcd_grpc_requests_total`. Once the upgrade is complete and all etcd nodes are running 3.1, migrate to the `grpc_server_handled_total` metric at your leisure.
This PR reorganizes the code substantially. Previously, the code to proxy etcd metrics was hard coded and limited to a single counter metric. This has been entirely replaced with code that generically filters, rewrites proxied etcd metrics and then aggregates them with custom metrics such as the etcd version metric.

We shouldn't upgrade etcd without first warning the user that some etcd
version transitions can't be undone. We don't know what version the user
currently has, so we require either an explicit version and image, or an
interactive acknowledgement of this caveat.

fluend-gcp already has these tolerations. kube-proxy when it runs as a
static pod gets wildcard `NoExecute` toleration (all static pods get
that). So, added the same toleration to kube-proxy when it runs as a
daemonset. Also added wildcard `NoSchedule` toleration to kube-proxy.
It is expected that nodes with extended resources attached will be
tainted with the resouce name, so that we can create dedicated nodes.
If ExtendedResourceToleration admission controller is enabled, pods
requesting such resources will automatically tolerate such taints.
nvidia-gpu-device-plugin daemonset doesn't request such resources but
still needs to run on such nodes, so it needs this toleration.

Fix prometheus-to-sd sidecar in metadata proxy
Ref https://github.com/kubernetes/kubernetes/issues/55695#issuecomment-344300188
This is making 2 changes:
- restoring resource requests and limits of the metadata-proxy sidecar as it was before, and remove them for prom-to-sd sidecar (best effort) like at everywhere else
- pass pod name and namespace args to prom-to-sd sidecar (because just noticed)

Use results of kube-controller-manager leader election in addon manager
**What this PR does / why we need it**:
This adds leader election-like mechanism to addon manager. Currently, in a multi-master setup, upgrading one master will trigger a fight between addon managers on different masters, each forcing its own versions of addons. This leads to pod unavailability until all masters are upgraded to new version.
To avoid implementing leader election in bash, results of leader election in kube-controller-manager are used. Long term, addon manager probably should be rewritten in a real prgramming language (probably Go), and then, real leader election should be implemented there.

Run nvidia-gpu device-plugin daemonset as an addon on GCE nodes that have nvidia GPUs attached
- Instead of the old `Accelerators` feature that added `alpha.kubernetes.io/nvidia-gpu` resource, use the new `DevicePlugins` feature that adds vendor specific resources. (In case of nvidia GPUs it will
add `nvidia.com/gpu` resource.)
- Add node label to GCE nodes with accelerators attached. This node label is the same as what GKE attaches to node pools with accelerators attached. (For example, for nvidia-tesla-p100 GPU, the label would be `cloud.google.com/gke-accelerator=nvidia-tesla-p100`) This will help us target accelerator specific
daemonsets etc. to these nodes.
- Run nvidia-gpu device-plugin daemonset as an addon on GCE nodes that have nvidia GPUs attached.
- Some minor documentation improvements in addon manager.
**Release note**:
```release-note
GCE nodes with NVIDIA GPUs attached now expose `nvidia.com/gpu` as a resource instead of `alpha.kubernetes.io/nvidia-gpu`.

Remove Google Cloud KMS's in-tree integration
Removes the following introduced by #48574 and others:
* `kms.go` which contained the cloudkms-specific code for Google Cloud KMS service.
* Registering the Google Cloud KMS in the KMS plugin registry.
* Google's `cloudkms` API package from `vendor` folder.
The following changes are upcoming:
* Removal of KMSPluginRegistry. This would not be needed anymore, since KMS providers will be out-of-tree from now on (so no need of registering them, an address of the process would be enough).
* A service which allows encrypt/decrypt functionality (satisfies `envelope.Service` interface) if initialized with an IP/Port of an out-of-tree process serving KMS requests. Will tentatively use gRPC requests to talk to this external service.
Reference: https://github.com/kubernetes/kubernetes/pull/54439#issuecomment-340062801 and https://github.com/kubernetes/kubernetes/issues/51965#issuecomment-339333937.

Add support to for alternative container runtime in `kube-up.sh`
For https://github.com/kubernetes/features/issues/286.
This PR added 4 new environment variables in `kube-up.sh` to support alternative container runtime:
1) `KUBE_MASTER_EXTRA_METADATA` and `KUBE_NODE_EXTRA_METADATA`. Add extra metadata on master and node instance. With this we could specify different cloud-init for a different container runtime, and also add extra metadata for the new cloud-init, e.g. [master.yaml](7d73966214/test/e2e/master.yaml)
2) `KUBE_CONTAINER_RUNTIME_ENDPOINT`. Specify different sock for different container runtime. It's only used when it's not empty.
3) `KUBE_LOAD_IMAGE_COMMAND`. Specify different load image command for different container runtime.
An example for cri-containerd:
```
export KUBE_MASTER_EXTRA_METADATA="user-data=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/e2e/master.yaml,cri-containerd-configure-sh=${GOPATH}/src/github.com/kubernetes-incubator/cri-containerd/test/configure.sh"

Basic GCE PodSecurityPolicy Config
**What this PR does / why we need it**:
This PR lays the foundation for enabling PodSecurityPolicy in GCE and other default deployments. The 3 commits are:
1. Add policies, roles & bindings for the default addons on GCE.
2. Enable the PSP admission controller & load the addon policies when the`ENABLE_POD_SECURITY_POLICY=true` environment variable is set.
3. Support the PodSecurityPolicy in the E2E environment & add PSP tests.

```release-note
Add support for PodSecurityPolicy on GCE: `ENABLE_POD_SECURITY_POLICY=true` enables the admission controller, and installs policies for default addons.
```
This node label is the same as what GKE attaches to node pools with
accelerators attached. This will help us target accelerator specific
daemonsets etc. to these nodes.
Instead of the old Accelerators feature that added
alpha.kubernetes.io/nvidia-gpu resource, use the new DevicePlugins
feature that adds vendor specific resources. (In case of nvidia it will
add nvidia.com/gpu resource.)
The grace period is unneccessary for calico/node and it delays restart of
a new calico/node pod to take over routing and policy updates.
Setting the grace period to 0 has the special meaning of doing a force deletion,
which avoids a slow round-trip through the kubelet and API server.

Introduce GCE-specific addons directory
**What this PR does / why we need it**:
GCE & GKE currently rely on the cluster bringup defined in the `cluster/gce` directory, but there isn't a good way of deploying GCE specific manifests. Currently the 2 approaches are, put it in `/cluster/addons`, which implies it should be generally useful (not GCE specific), or it is synthesized by one of the bash scripts in `cluster/gce`.
This PR introduces a straightforward way to have GCE-specific manifests deployed for GCE & GKE, without the need to pollute the general addon space.

Remove federation
This PR removes the federation codebase and associated tooling from the tree.
The first commit just removes the `federation` path and should be uncontroversial. The second commit removes references and associated tooling and suggests careful review.
Requirements for merge:
- [x] Bazel jobs no longer hard-code federation as a target ([test infra #4983](https://github.com/kubernetes/test-infra/pull/4983))
- [x] `federation-e2e` jobs are not run by default for k/k
**Release note**:
```release-note
Development of Kubernetes Federation has moved to github.com/kubernetes/federation. This move out of tree also means that Federation will begin releasing separately from Kubernetes. The impact of this is Federation-specific behavior will no longer be included in kubectl, kubefed will no longer be released as part of Kubernetes, and the Federation servers will no longer be included in the hyperkube binary and image.

Load kernel modules automatically inside a kube-proxy pod
**What this PR does / why we need it**:
This change will mount `/lib/modules` on host to the kube-proxy pod,
so that a kube-proxy pod can load kernel modules by need
or when `modprobe <kmod>` is run inside the pod.
This will be convenient for kube-proxy running in IPVS mode.
Users will don't have to run `modprobe ip_vs` on nodes before starting
a kube-proxy pod.
**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**:
The kube-proxy IPVS proxier will check if the kernel supports IPVS, or it will fallback to iptables or userspace modes. There is a false negative condition in the check, #51874 addressed that issue.

kube-dns-anti-affinity: kube-dns never-co-located-in-the-same-node
**What this PR does / why we need it**:
This is upstreaming the kubernetes/kops#2705 pull request by @jamesbucher that was originally against [kops](github.com/kubernetes/kops).
Please see kubernetes/kops#2705 for more details, including a lengthy discussion.
Briefly, given the constraints of how the system works today:
+ if you need multiple DNS pods primarily for availability, then requiredDuringSchedulingIgnoredDuringExecution makes sense because putting more than one DNS pod on the same node isn't useful
+ if you need multiple DNS pods primarily for performance, then
preferredDuringScheduling IgnoredDuringExecution makes sense because it will allow the DNS pods to schedule even if they can't be spread across nodes
**Which issue this PR fixes**
fixeskubernetes/kops#2693
**Release note**:
```release-note
Improve resilience by annotating kube-dns addon with podAntiAffinity to prefer scheduling on different nodes.

[GCE kube-up] Don't provision kubeconfig file for kube-proxy service account
**What this PR does / why we need it**:
Offloading the burden of provisioning kubeconfig file for kube-proxy service account from GCE startup scripts. This also helps us decoupling kube-proxy daemonset upgrade from node upgrade.
Previous attempt on https://github.com/kubernetes/kubernetes/pull/51172, using InClusterConfig for kube-proxy based on discussions on https://github.com/kubernetes/client-go/issues/281.

[GCE kube-up] Allow creating/deleting custom network
**What this PR does / why we need it**:
From https://github.com/kubernetes/test-infra/issues/4472.

This allows the etcd docker registry that is currently hard coded to
`gcr.io/google_containers/etcd` in the `etcd.manifest` template to be
overridden. This can be used to test new versions of etcd with
kubernetes that have not yet been published to
`gcr.io/google_containers/etcd` and also enables cluster operators to
manage the etcd images used by their cluster in an internal
repository.

Add launching Cluster Autoscaler in Kubemark
**What this PR does / why we need it**:
Allows to launch Cluster Autoscaler in Kubemark.
To do it, set ENABLE_KUBEMARK_CLUSTER_AUTOSCALER flag to true. This currently only works with one nodegroup, for which you can specify minimum and maximum number of nodes and name. (KUBEMARK_AUTOSCALER_MIN_NODES, KUBEMARK_AUTOSCALER_MAX_NODES, KUBEMARK_AUTOSCALER_MIG_NAME).
Is is important to note that NUM_NODES has a different meaning when launching Cluster Autoscaler - we always start with only one node, but NUM_NODES is used to calculate the size of Kubemark master and addon components.
There are no changes to the current setup if ENABLE_KUBEMARK_CLUSTER_AUTOSCALER is set to false.
**Release note**:
```
NONE
```
This change will mount `/lib/modules` on host to the kube-proxy pod,
so that a kube-proxy pod can load kernel modules by need
or when `modprobe <kmod>` is run inside the pod.
This will be convenient for kube-proxy running in IPVS mode.
Users will don't have to run `modprobe ip_vs` on nodes before starting
a kube-proxy pod.
