Add HA/LB endpoints for kube-apiserver * Add HA docs for API server. * Add auto-evaluated internal endpoints and clarify the loadbalancer_apiserver vars and usecases. * Use facts for kube_apiserver to not repeat code and enable LB endpoints use. * Use /healthz check for the wait-for apiserver. * Use the single endpoint for kubelet instead of the list of apiservers * Specify kube_apiserver_count to for HA layout Signed-off-by: Bogdan Dobrelya <bdobrelia@mirantis.com> 2016-07-13 23:13:47 +08:00			`KUBERNETES_MASTER={{ first_kube_master }}`

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 Signed-off-by: Bogdan Dobrelya <bdobrelia@mirantis.com> Co-authored-by: Matthew Mosesohn <mmosesohn@mirantis.com> 2016-07-11 22:05:05 +08:00			`ETCD_AUTHORITY={{ etcd_authority }}`
