Metadata Agent Improvements
Bump metadata agent version to 0.2-0.0.21-1.
Expand the metadata agent's access to all API groups.
Remove metadata agent config maps in favor of command line flags.
Update the metadata agent's liveness probe to a new /healthz handler.
Logging Agent Improvements
Bump logging agent version to 0.2-1.5.33-1-k8s-1.
Appropriately set log severity for k8s_container.
Fix detect exceptions plugin to analyze message field instead of log field.
Fix detect exceptions plugin to analyze streams based on local resource id.
Disable the metadata agent for monitored resource construction in logging.
Disable timestamp adjustment in logs to optimize performance.
Reduce logging agent buffer chunk limit to 512k to optimize performance.
In addition to the shell script changes the heapster yaml has been
updated to use addon resizer 1.8.3 for the heapster-nanny. Addon resizer 1.8.3
is being used to take advantage of the new minClusterSize flag. Note this is a
no-op change. The values specified for heapster-nanny reflect the current
configuration used with version 1.8.2.

Create system:cluster-autoscaler account & role and introduce it to C…
**What this PR does / why we need it**:
This PR adds cluster-autoscaler ClusterRole & binding, to be used by the Cluster Autoscaler (kubernetes/autoscaler repository).
It also updates GCE scripts to make CA use the cluster-autoscaler user account.
User account instead of Service account is chosen to be more in line with kube-scheduler.
**Which issue(s) this PR fixes**:
Fixes [issue 383](https://github.com/kubernetes/autoscaler/issues/383) from kubernetes/autoscaler.
**Special notes for your reviewer**:
This PR might be treated as a security fix since prior to it CA on GCE was using system:cluster-admin account, assumed due to default handling of unsecured & unauthenticated traffic over plain HTTP.
**Release note**:
```release-note
A cluster-autoscaler ClusterRole is added to cover only the functionality required by Cluster Autoscaler and avoid abusing system:cluster-admin role.
action required: Cloud providers other than GCE might want to update their deployments or sample yaml files to reuse the role created via add-on.

Revert "Remove rescheduler and corresponding tests from master"
Reverts kubernetes/kubernetes#64364
After discussing with @bsalamat on how DS controllers(ref: https://github.com/kubernetes/kubernetes/pull/63223#discussion_r192277527) cannot create pods if the cluster is at capacity and they have to rely on rescheduler for making some space, we thought it is better to
- Bring rescheduler back.
- Make rescheduler priority aware.
- If cluster is full and if **only** DS controller is not able to create pods, let rescheduler be run and let it evict some pods which have less priority.
- The DS controller pods will be scheduled now.
So, I am reverting this PR now. Step 2, 3 above are going to be in rescheduler.

gce: Prefer MASTER_ADVERTISE_ADDRESS in apiserver setup
MASTER_ADVERTISE_ADDRESS is used to set the --advertise-address flag
for the apiserver. It's useful for running the apiserver behind a load
balancer.
However, if PROJECT_ID, TOKEN_URL, TOKEN_BODY, and NODE_NETWORK are
all set, the GCE VM's external IP address will be fetched and used
instead and MASTER_ADVERTISE_ADDRESS will be ignored.
Change this behavior so that MASTER_ADVERTISE_ADDRESS takes precedence
because it's more specific. We still fall back to using the VM's
external IP address if the other variables are set.
Also: Move the setting of --ssh-user and --ssh-keyfile based on
PROXY_SSH_USER) to a top-level block because this is common to all
codepaths.

Install and use crictl in gce kube-up.sh
Download and use crictl in gce kube-up.sh.
This PR:
1. Downloads crictl `v1.0.0-beta.0` onto the node, which supports CRI v1alpha2. We'll upgrade it to `v1.0.0-beta.1` soon after the release is cut.
2. Change `kube-docker-monitor` to `kube-container-runtime-monitor`, and let it use `crictl` to do health monitoring.
3. Change `e2e-image-puller` to use `crictl`. Because of https://github.com/kubernetes/kubernetes/issues/63355, it doesn't work now. But in `crictl v1.0.0-beta.1`, we are going to statically link it, and the `e2e-image-puller` should work again.
4. Use `systemctl kill --kill-who=main` instead of `pkill`, the reason is that:
a. `pkill docker` will send `SIGTERM` to all processes including `dockerd`, `docker-containerd`, `docker-containerd-shim`. This is not a problem for Docker 17.03 CE, because `containerd-shim` in containerd 0.2.x doesn't exit with SIGERM (see [code](https://github.com/containerd/containerd/blob/v0.2.x/containerd-shim/main.go#L123)). However, `containerd-shim` in containerd 1.0+ does exit with SIGTERM (see [code](https://github.com/containerd/containerd/blob/master/cmd/containerd-shim/main_unix.go#L200)). This means that `pkill docker` and `pkill containerd` will kill all shim processes for Docker 17.11+ and containerd 1.0+.
b. We can use `pkill -x` instead. However, docker systemd service name is `docker`, but daemon process name is `dockerd`. We have to introduce another environment variable to specify "daemon process name". Given so, it seems easier to just use `systemctl kill` which only requires systemd service name. `systemctl kill --kill-who=main` will make sure only main process receives SIGTERM.

Add unit test for configure-helper.sh.
**What this PR does / why we need it**:
Add a framework for unit-testing configure-helper.sh.
configure-helper.sh plays a critical role in initializing clusters both on GCE and GKE. It is currently, over 2K lines of code, yet it has no unit test coverage.
This PR proposes a framework/approach on how to provide test coverage for this component.
Notes:
1. Changes to configure-helper.sh itself were necessary to enable sourcing of this script for the purposes of testing.
2. As POC api_manifest_test.go covers the logic related to the initialization of apiserver when integration with KMS was requested. The hope is that the same approach could be extended to the rest of the script.

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:

GCE: Create cloud-provider roles and bindings via addons
**What this PR does / why we need it**:
This removes the `cloud-provider` role and role binding from the rbac boostrapper and replaces it with a policy applied via addon mgr. This also creates a new clusterrole allowing the service account to create events for any namespace.
**Special notes for your reviewer**:
/assign @bowei @timstclair
/cc timstclair
**Release note**:
```release-note
GCE: A role and clusterrole will now be provided with GCE/GKE for allowing the cloud-provider to post warning events on all services and watching configmaps in the kube-system namespace.
```
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.

Add a new environment variable to the gce startup scripts called KUBE_PROXY_MODE
**What this PR does / why we need it**:
This PR adds a new environment variable called KUBE_PROXY_MODE to the startup scripts for gce. This variable will allow a user to specify the kube-proxy implementation they want to use, with the choices being ipvs or iptables (iptables is default).
Next steps:
1. Need to remove use of feature gateway when IPVS goes GA
2. Need to add logic of loading required ipvs kernel modules in the scripts
Question: If the proxier is IPVS, is it necessary to have the iptables sync period flags?
**Release note**:
```release-note

This is the 2nd attempt. The previous 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.

* move limit-range into gce/addons/limit-range
* move abac jsonl into gce/manifests. this is gross but we will
hopefully be able to delete this config soon. it only exists to support
a deprecated feature.
* fix build, release, deploy to look for everything in its new home
- If REMOUNT_VOLUME_PLUGIN_DIR is set to true, VOLUME_PLUGIN_DIR is remounted with `exec` option during cluster startup. This allows any writable location to be used as the plugin directory.
- New HostPath added to controller-manager deployment to enable access to volume plugin directory.
- Improved how the default directory is passed to master and node setup.

Add options for mounting SCSI or NVMe local SSD though Block or Filesystem and do all of that with UUID
Fixes: #51431
Fixed version of: #53466
Mount SCSI local SSD by UUID in /mnt/disks/by-uuid/, also allows for users to request and mount NVMe disks. Both types of disks will be accessible either through block or file-system.
I have confirmed that it is no longer crashing when nodes are initialized on GKE.
Lack of this flag sometimes causes iptables to return error code 4 (if
other process holds xtables lock). As a result, because of `set -o errexit`,
whole startup script fails, leaving master in an incorrect state.

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"

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
