Add Calico as policy provider in GCE
Adds Calico as policy provider to GCE, enforcing the extensions/v1beta1 NetworkPolicy API.
Still to do:
- [x] Enable NetworkPolicy API when POLICY_PROVIDER is provided.
- [x] Fix CNI plugin, policy controller versions.

Tracked addition of federation, sed support in kube DNS
[]()
The kube DNS app recently gained support for federation (whatever that
is), including a new Salt parameter. This broke the deployAddons.sh script for cluster ubuntu. The DNS app also gained alternate
templates, intended to be friendly to `sed`. Fortunately, those do
not demand a federation parameter.
This PR fixes up the ` cluster/ubuntu/deployAddons.sh` script to track those changes, by switching to the `sed`-friendly templates.

mount instanceid file from config drive when using openstack cloud provider
fix https://github.com/kubernetes/kubernetes/issues/23191, the instanceid file is read however we do not mount it as a volume, and it would cause the cloud provider contacts the metadata server, in some cases, the metadata server is not able to serve, then the cloud provider would fail to initialize, we should avoid that.

federation: Updating KubeDNS to try finding a local service first for federation query
Ref https://github.com/kubernetes/kubernetes/issues/26762
Updating KubeDNS to try to find a local service first for federation query.
Without this change, KubeDNS always returns the DNS hostname, even if a local service exists.
Have updated the code to first remove federation name from path if it exists, so that the default search for local service happens. If we dont find a local service, then we try to find the DNS hostname.
Will appreciate a strong review since this is my first change to KubeDNS.
https://github.com/kubernetes/kubernetes/pull/25727 was the original PR that added federation support to KubeDNS.

Support journal logs in fluentd-gcp on GCI
This maintains a single common image for each rather than having to fork out separate images, relying on different commands in yaml manifests to differentiate in the behavior. This is treading on top of @adityakali's #27906, but I wasn't able to get in touch with him this afternoon until very recently. He's handling making sure that the new yaml manifests are used when running on GCI.
```release-note
```
Only run the systemd-journal plugin when on a platform that requests it.
The plugin crashes the fluentd process if the journal isn't present, so
it can't just be run blindly in all configurations.

Update to dnsmasq:1.3 and make hyperkube always use the latest addons
This bumps dnsmasq to a version that works on all architectures: https://github.com/kubernetes/contrib/pull/1192 (which have to be pushed first indeed)
Also I removed the manifests in hyperkube addons in favor for machine-generated ones, which will avoid mistakes.
This one is required for `v1.3`, so it has to be cherrypicked I think...
It makes docker and docker-multinode addons work again...
(Yes, we'll probably get rid of docker in favor for minikube, but we'll have to have it in this release at least)

This works around a linux kernel bug with overly aggressive caching of
ARP entries, which was causing problems when we reused IP addresses in
VPCs, for example with an ASG in a relatively small subnet.
See #23395 for more explanation.
Fixes#23395
Vivid is EOL, and Docker is no longer packaged for it.
Remove support for it in 1.3 (in 1.2 we had warned users it was EOL).
Also remove unused wheezy, trusty & coreos & do general cleanup.
Implement basic cloud provider functionality to deploy Kubernetes on
Azure. SaltStack is used to deploy Kubernetes on top of Ubuntu
virtual machines. OpenVpn provides network connectivity. For
kubelet authentication, we use basic authentication (username and
password). The scripts use the legacy Azure Service Management APIs.
We have set up a nightly test job in our Jenkins server for federated
testing to run the e2e test suite on Azure. With the cloud provider
scripts in this commit, 14 e2e test cases pass in this environment.
We plan to implement additional Azure functionality to support more
test cases.
This first reverts commit 8e8437dad8.

NICs from the other NICs (like the CBR). This doesn't rely on the
unreliable reporting of the portgroup.
- Persist route changes. We configure routes on the master and nodes,
but previously we didn't persist them so they didn't last across

Initial kube-up support for VMware's Photon Controller
This is for: https://github.com/kubernetes/kubernetes/issues/24121
Photon Controller is an open-source cloud management platform. More
information is available at:
http://vmware.github.io/photon-controller/
This commit provides initial support for Photon Controller. The
following features are tested and working:
- kube-up and kube-down
- Basic pod and service management
- Networking within the Kubernetes cluster
- UI and DNS addons
It has been tested with a Kubernetes cluster of up to 10
nodes. Further work on scaling is planned for the near future.
Internally we have implemented continuous integration testing and will
run it multiple times per day against the Kubernetes master branch
once this is integrated so we can quickly react to problems.
A few things have not yet been implemented, but are planned:
- Support for kube-push
- Support for test-build-release, test-setup, test-teardown
Assuming this is accepted for inclusion, we will write documentation
for the kubernetes.io site.
We have included a script to help users configure Photon Controller
for use with Kubernetes. While not required, it will help some
users get started more quickly. It will be documented.
We are aware of the kube-deploy efforts and will track them and
support them as appropriate.

Create a new Deployment in kube-system for every version.
It appears that version numbers have already been properly added to these files. Small change to delete an old deployment entirely, so we can make a new one per version (like replication controllers).

Allow the gcr.io/google_containers registry to be overridden
regionally by just blasting a new KUBE_ADDON_REGISTRY out. Instead of
adding every addon to Salt and asking all of the other consumers
(Trusty, Juju, Mesos, etc) to change, just script the sed ourselves.
This is probably the 9th grossest thing I've ever done, but it works
well, and it works quickly. I kind of wish it didn't.
It includes some performance improvements for parsing JSON (which is
very important for us, since all Docker logs are JSON) as well as a
couple new settings, like forcing of a flush of multiline logs after a
time period rather than having to wait until a new log is seen before
feeling confident flushing the previous one.
-Remove CPU limits to enable CPU bursting once 1.2 begins enforcing CPU limits.
-Add a memory limit for fluentd-es to match fluentd-gcp.
-Explicitly set requests to match limits.
This change revises the way to provide kube-system manifests for clusters on Trusty. Originally, we maintained copies of some manifests under cluster/gce/trusty/kube-manifests, which is not scalable and hard to maintain. With this change, clusters on Trusty will use the same source of manifests as ContainerVM. This change also fixes some minor problems such as shell variables and comments to meet the style guidance better.
Starting docker through Salt has always been problematic. Kubelet or
the babysitter process should start it. We've kept it around primarily
so we have a `service: docker` node for the Salt DAG.
Instead, we enable (but do not start) the Docker service in Salt. This
lets us keep the DAG node, but won't start it.
There's another bug in Salt, where watches will start the service even
on `service.enabled`. So we remove the watches, and move them to our
existing Salt bug-fix script.
The Docker 1.9.1 package on Debian is broken, and the service fails to
install when run unattended. This is treated as an installation failure
and causes everything to fail.
However, the service can be started by Salt once we're not installing
the package, and indeed we restart docker anyway.
So, on Debian, use a helper script to install the docker package. The
script sets up a policy-rc.d file to prevent the service starting, and
then cleanly removes it afterwards (this would be difficult to do in
Salt, I believe).
for vsphere provider docker currently only supports 1.9.1 release.
The older versions of docker are failing on jessie due to issue https://github.com/docker/docker/issues/18793
and newer version 1.10.x is not properly tested.
In commit 07d7cfd3, people add ${DEBUG} == "true" in file
cluster/saltbase/salt/generate-cert/make-ca-cert.sh
But the default value for DEBUG is not set. In that commit, it set the value
of DEBUG in cluster/ubuntu/util.sh where it call this script. When using this
script in saltstack to bring up cluster in other cloud platforms, it will fail
to generate the cert since we set set -o nounset in make-ca-cert.sh and var DEBUG
does not set. Set a default value for DEBUG here will fix this problem.
This is good because it removes an obstacle to using the
cluster/ubuntu scripting to install Kubernetes into a restricted
environment where the machines can not open connections to arbitrary
external locations.
Also add debuggability to make-ca-cert.sh

The version of Salt we're running doesn't do a good job of detecting
systemd. Inspired by https://github.com/saltstack/salt/issues/13926,
I added a provider-force to the services.
With this change, salt-call -l debug state.highstate succeeds, even for
repeated invocations.
The issue was (probably) benign, but definitely caused noised (e.g. #11297)
I got the package name wrong before, which meant that salt was failing
on invocations after the first (the name apparently doesn't matter on
the first invocation).
We've had a lot of salt problems with systemd on AWS; we have a
workaround in place that we use everywhere else, we should use that for
kube-node-unpacker too.

To build the python image, BUILD_PYTHON_IMAGE should be set during make.
When the addon script is running, it will check if python is installed
on the machine, if not, it will use the python image that built previously.
When KUBE_E2E_STORAGE_TEST_ENVIRONMENT is set to 'true', kube-up.sh script
will:
- Install the right packages for all storage volumes.
- Use devicemapper as docker storage backend. 'aufs', the default one on
Debian, does not support extended attibutes required by Ceph RBD and Gluster
server containers.
Tested on GCE and Vagrant, e2e tests for storage volumes passes without any
additional configuration.
This ensures nfs-common is installed on GCE, and provides a more
functional explanation/example. I launched two replication controllers
so that there were busybox pods to poke around at the NFS volume, and
so that the later wget actually works (the original example would have
to work on the node, or need some other access to the container
network). After switching to two controllers, it actually makes more
sense to use PV claims, and it's probably a configuration that makes
more sense for indirection for NFS anyways.
We want to match the version of netcat that is installed on GCE. We
were having problems with netcat-openbsd having slightly different
timeout behaviour (on UDP packets; when there was no listener).
This scopes down the initially ambitious PR:
https://github.com/kubernetes/kubernetes/pull/14960 to replace just
`pause` and `fluentd-elasticsearch` to come through `beta.gcr.io`.
The v2 versions have been pushed under new tags, `pause:2.0` and
`fluentd-elastisearch:1.12`.
NOTE: `beta.gcr.io` will still serve images using v1 until they are repushed with v2. Pulls through `gcr.io` will still work after pushing through `beta.gcr.io`, but will be served over v1 (via compat logic).
OpenContrail is an open-source based networking software which provides virtualization support for the cloud.
This change-set adds ability to install and provision opencontrail software for networking in kubernetes based cloud environment.
There are basically 3 components
o kube-network-manager -- plugin between contrail components and kubernets components
o provision_master.sh -- OpenContrail software installer and provisioner in master node
o provision_minion.sh -- OpenContrail software installer and provisioner in minion node(s)
These are driven via salt configuration files
One can provision opencontrail by just setting "export NETWORK_PROVIDER=opencontrail"
Optionally, OPENCONTRAIL_TAG, and OPENCONTRAIL_KUBERNETES_TAG can be used to
specify opencontrail and contrail-kubernetes software versions to install and provision.
Public-IP Subnet provided by contrail can be configured via OPENCONTRAIL_PUBLIC_SUBNET
environment variable
At this moment, plan is to add support for aws, gce and vagrant based platforms

Along with this, separate logs from containers in the cluster out from

Also let it log things by not redirecting to a file within the container
and only using -q (warning logs only) rather than -qq (error logs only).
This registry can be accessed through proxies that run on each node
listening on port 5000. We send the proxy images to the nodes directly
to avoid requests that hit the network during cluster launch. For now,
we continue to pull the registry itself over the network, especially
given its large size (we should be able to dramatically shrink the
image). On GCE we create a PD and use that for storage, otherwise we
use an emptyDir. The registry is not enabled outside of GCE. All
communication is currently plain HTTP. In order to use SSL, we will
need to be able to request a certificate/key from the apiserver signed
by the apiserver's CA cert.
