Do not override kubelet hostname if cloud_provider is used (#2095)
Starting with Kubernetes v1.8.4, kubelet ignores the AWS cloud
provider string and uses the override hostname, which fails
Node admission checks.

Fixes #2094

e78562830f Retry kube container removal during upgrade
As we have seen with other containers, sometimes container removal fails on the first attempt due to some Docker bugs. Retrying typically corrects the issue.

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

Defaults for apiserver_loadbalancer_domain_name (#1993)
* Defaults for apiserver_loadbalancer_domain_name

When loadbalancer_apiserver is defined, use the
apiserver_loadbalancer_domain_name with a given default value.

Fix unconsistencies for checking if apiserver_loadbalancer_domain_name
is defined AND using it with a default value provided at once.

* Define defaults for LB modes in common defaults

e9f795c5ce Master component and kubelet container upgrade fixes
* Fixes an issue where apiserver and friends (controller manager, scheduler) were prevented from restarting after manifests/secrets are changed. This occurred when a replaced kubelet doesn't reconcile new master manifests, which caused old master component versions to linger during deployment. In my case this was causing upgrades from k8s 1.6/1.7 -> k8s 1.8 to fail
* Improves transitions from kubelet container to host kubelet by preventing issues where kubelet container reappeared during the deployment

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`

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.

1cfe0beac0 Set ClusterFirstWithHostNet for Pods with hostnetwork: true
In kubernetes 1.6 ClusterFirstWithHostNet was added as an option. In
accordance to it kubelet will generate resolv.conf based on own
resolv.conf. However, this doesn't create 'options', thus the proper
solution requires some investigation.

This patch sets the same resolv.conf for kubelet as host

bff955ff7e Mount host's /var/log into kubelet container
Kubelet is responsible for creating symlinks from /var/lib/docker to /var/log
to make fluentd logging collector work.
However without using host's /var/log those links are invisible to fluentd.

This is done on rkt configuration too.

a15d626771 Preconfigure DNS stack and docker early
In order to enable offline/intranet installation cases:
* Move DNS/resolvconf configuration to preinstall role. Remove
  skip_dnsmasq_k8s var as not needed anymore.

* Preconfigure DNS stack early, which may be the case when downloading
  artifacts from intranet repositories. Do not configure
  K8s DNS resolvers for hosts /etc/resolv.conf yet early (as they may be
  not existing).

* Reconfigure K8s DNS resolvers for hosts only after kubedns/dnsmasq
  was set up and before K8s apps to be created.

* Move docker install task to early stage as well and unbind it from the
  etcd role's specific install path. Fix external flannel dependency on
  docker role handlers. Also fix the docker restart handlers' steps
  ordering to match the expected sequence (the socket then the service).

* Add default resolver fact, which is
  the cloud provider specific and remove hardcoded GCE resolver.

* Reduce default ndots for hosts /etc/resolv.conf to 2. Multiple search
  domains combined with high ndots values lead to poor performance of
  DNS stack and make ansible workers to fail very often with the
  "Timeout (12s) waiting for privilege escalation prompt:" error.

* Update docs.

Fixes #655.

This is a teporary solution for long-polling idle connections to
apiserver. It will make Nginx not cut them for the duration of expected
timeout. It will also make Nginx extremely slow in realizing that there
is some issue with connectivity to apiserver as well, so it might not be
perfect permanent solution.

By default, the kubelet will try to pull each image from the
specified registry. However, if the imagePullPolicy property
of the container is set to IfNotPresent or Never, then a local\
image is used (preferentially or exclusively, respectively).

8168689caa Refactor roles and hosts
Shorten deployment time with:
- Remove redundand roles if duplicated by a dependency and vice versa
- When a member of k8s-cluster, always install docker as a dependency
  of the etcd role and drop the docker role from cluster.yaml.
- Drop etcd and node role dependencies from master role as they are
  covered by the node role in k8s-cluster group as well. Copy defaults
  for master from node role.
- Decouple master, node, secrets roles handlers and vars to be used w/o
  cross references.

e8a1c7a53f Move docker systemd unit creation to docker role
Creating the unit using default settings early on
and then changing it during network_plugin section
leads to too many docker restarts and duplicated code.

Reversed Wants= dependence on docker.service so it does not
restart docker when reloading systemd

Consolidated all docker restart handlers.

    Delegate=yes
    KillMode=process.
* Add missed DOCKER_OPTIONS for calico/weave docker systemd unit.
* Change Requires= to a less strict and non-faily Wants=, add missing
  Wants= for After=.
* Align wants/after in a wat if Wants=foo, After= has foo as well.
* Make wants/after docker.service to ask for the docker.socket as well.
* Move "docker rm -f" commands from ExecStartPre= to ExecStopPost=.
  hooks to ensure non-destructive start attempts issued by Wants=.

1b1f5f22d4 Fix etcd standalone deployment
etcd facts are generated in kubernetes/preinstall, so etcd nodes need
to be evaluated first before the rest of the deployment.

Moved several directory facts from kubernetes/node to
kubernetes/preinstall because they are not backward dependent.

a70c3b661e Add HA/LB endpoints for kube-apiserver
* Add auto-evaluated internal endpoints and clarify the loadbalancer_apiserver
vars and usecases.
* Add loadbalancer_apiserver_localhost (default false). If enabled, override
the external LB and expect localhost:443/8080 to be new internal only frontends.
* Add kube_apiserver_multiaccess to ignore loadbalancers, and make clients
to access the apiservers as a comma-separated list of access_ip/ip/ansible ip
(a default mode). When disabled, allow clients to use the given loadbalancers.
* Define connections security mode for kube controllers, schedulers, proxies.
It is insecure be default, which is the current deployment choice.
* Rework the groups['kube-master'][0] hardcode defining the apiserver
endpoints.
* Improve grouping of vars and add facts for kube_apiserver.
* Define kube_apiserver_insecure_bind_address as a fact, add more
facts for ease of use.

32cd6e99b2 Add etcd proxy support
* Enforce a etcd-proxy role to a k8s-cluster group members. This
provides an HA layout for all of the k8s cluster internal clients.
* Proxies to be run on each node in the group as a separate etcd
instances with a readwrite proxy mode and listen the given endpoint,
which is either the access_ip:2379 or the localhost:2379.
* A notion for the 'kube_etcd_multiaccess' is: ignore endpoints and
loadbalancers and use the etcd members IPs as a comma-separated
list. Otherwise, clients shall use the local endpoint provided by a
etcd-proxy instances on each etcd node. A Netwroking plugins always
use that access mode.
* Fix apiserver's etcd servers args to use the etcd_access_endpoint.
* Fix networking plugins flannel/calico to use the etcd_endpoint.
* Fix name env var for non masters to be set as well.
* Fix etcd_client_url was not used anywhere and other etcd_* facts
evaluation was duplicated in a few places.
* Define proxy modes only in the env file, if not a master. Del
an automatic proxy mode decisions for etcd nodes in init/unit scripts.
* Use Wants= instead of Requires= as "This is the recommended way to
hook start-up of one unit to the start-up of another unit"
* Make apiserver/calico Wants= etcd-proxy to keep it always up

bedcca922c Add variables and defaults for multiple types of ip addresses.
Each node can have 3 IPs.
1. ansible_default_ip4 - whatever ansible things is the first IPv4 address
   usually with the default gw.
2. ip - An address to use on the local node to bind listeners and do local
   communication.  For example, Vagrant boxes have a first address that is the
   NAT bridge and is common for all nodes.  The second address/interface should
   be used.
3. access_ip - An address to use for node-to-node access.  This is assumed to
   be used by other nodes to access the node and may not be actually assigned
   on the node.  For example, AWS public ip that is not assigned to node.

This updates the places addresses are used to use either ip or access_ip and walk
up the list to find an address.
