userspace and iptables

e5d353d0a7 contiv network support (#1914)
* Add Contiv support

Contiv is a network plugin for Kubernetes and Docker. It supports
vlan/vxlan/BGP/Cisco ACI technologies. It support firewall policies,
multiple networks and bridging pods onto physical networks.

* Update contiv version to 1.1.4

Update contiv version to 1.1.4 and added SVC_SUBNET in contiv-config.

* Load openvswitch module to workaround on CentOS7.4

* Set contiv cni version to 0.1.0

Correct contiv CNI version to 0.1.0.

* Use kube_apiserver_endpoint for K8S_API_SERVER

Use kube_apiserver_endpoint as K8S_API_SERVER to make contiv talks
to a available endpoint no matter if there's a loadbalancer or not.

* Make contiv use its own etcd

Before this commit, contiv is using a etcd proxy mode to k8s etcd,
this work fine when the etcd hosts are co-located with contiv etcd
proxy, however the k8s peering certs are only in etcd group, as a
result the etcd-proxy is not able to peering with the k8s etcd on
etcd group, plus the netplugin is always trying to find the etcd
endpoint on localhost, this will cause problem for all netplugins
not runnign on etcd group nodes.
This commit make contiv uses its own etcd, separate from k8s one.
on kube-master nodes (where net-master runs), it will run as leader
mode and on all rest nodes it will run as proxy mode.

* Use cp instead of rsync to copy cni binaries

Since rsync has been removed from hyperkube, this commit changes it
to use cp instead.

* Make contiv-etcd able to run on master nodes

* Add rbac_enabled flag for contiv pods

* Add contiv into CNI network plugin lists

* migrate contiv test to tests/files

Signed-off-by: Cristian Staretu <cristian.staretu@gmail.com>

* Add required rules for contiv netplugin

* Better handling json return of fwdMode

* Make contiv etcd port configurable

* Use default var instead of templating

* roles/download/defaults/main.yml: use contiv 1.1.7

0c824d5ef1 Fix kubelet container with alternate Docker data paths
Some time ago I think the hardcoded `/var/lib/docker` was required, but kubelet running in a container has been aware of the Docker path since at least as far back as k8s 1.6.

Without this change, you see a large number of errors in the kubelet logs if you installed with a non-default `docker_daemon_graph`

PID namespace sharing is disabled only in Kubernetes 1.7.
Explicitily enabling it by default could help reduce unexpected
results when upgrading to or downgrading from 1.7.

dbbe9419e5 Allow setting cgroup driver for kubelet
Red Hat family platforms run docker daemon with `--exec-opt
native.cgroupdriver=systemd`. When kubespray tried to start kubelet
service, it failed with:

Error: failed to run Kubelet: failed to create kubelet: misconfiguration: kubelet cgroup driver: "cgroupfs" is different from docker cgroup driver: "systemd"

Setting kubelet's cgroup driver to the correct value for the platform
fixes this issue. The code utilizes autodetection of docker's cgroup
driver, as different RPMs for the same distro may vary in that regard.
