Docker now has a dependency on libltdl7; we have to specify it manually
if we are installing docker using dpkg (vs using apt-get or similar,
which would pull it in automatically)

Enable setting up Kubernetes cluster in Ubuntu on Azure
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.

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.

- Improve reliability of network address detection by using MAC
address. VMware has a MAC OUI that reliably distinguishes the VM's
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
reboots. This persists them in /etc/network/interfaces
- Fix regression that didn't configure auth for kube-apiserver with
Photon Controller.
- Reliably run apt-get update: Not doing this can cause apt to fail.
- Remove unused nginx config in salt
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.
Use of NETWORK_PROVIDER=cni is documented as useable (as well as it's affects on the runtime args of kubelet),
however the actual implimentation in the salt automation doesnt seem to exist.
this change attempts to fix that for the vagrant usecase.
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.
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).
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.
