      Make dnsmasq daemon set optional · 82ee60fe
      Bogdan Dobrelya authored
      
      
      Change additional dnsmasq opts:
      - Adjust caching size and TTL
      - Disable resolve conf to not create loops
      - Change dnsPolicy to default (similarly to kubedns's dnsmasq). The
        ClusterFirst should not be used to not create loops
      - Disable negative NXDOMAIN replies to be cached
      - Make its very installation as optional step (enabled by default).
        If you don't want more than 3 DNS servers, including 1 for K8s, disable
        it.
      - Add docs and a drawing to clarify DNS setup.
      - Fix stdout logs for dnsmasq/kubedns app configs
      - Add missed notifies to resolvconf -u handler
      - Fix idempotency of resolvconf head file changes

      Add HA/LB endpoints for kube-apiserver · 731d32af
      Bogdan Dobrelya authored
      
      
      * 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

      Add etcd proxy support · 32cd6e99
      Bogdan Dobrelya authored
      
      
      * 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
