# For some environments, each node has a pubilcally accessible
# address and an address it should bind services to. These are
# really inventory level variables, but described here for consistency.
#
# When advertising access, the access_ip will be used, but will defer to
# ip and then the default ansible ip when unspecified.
#
# When binding to restrict access, the ip variable will be used, but will
# defer to the default ansible ip when unspecified.
#
# The ip variable is used for specific address binding, e.g. listen address
# for etcd. This is use to help with environments like Vagrant or multi-nic
# systems where one address should be preferred over another.
# ip: 10.2.2.2
#
# The access_ip variable is used to define how other nodes should access
# the node. This is used in flannel to allow other flannel nodes to see
# this node for example. The access_ip is really useful AWS and Google
# environments where the nodes are accessed remotely by the "public" ip,
# but don't know about that address themselves.
# access_ip: 1.1.1.1

# Internal DNS configuration.
# Kubernetes can create and mainatain its own DNS server to resolve service names
# into appropriate IP addresses. It's highly advisable to run such DNS server,
# as it greatly simplifies configuration of your applications - you can use
# service names instead of magic environment variables.
# You still must manually configure all your containers to use this DNS server,
# Kubernetes won't do this for you (yet).
# Upstream dns servers used by dnsmasq

# There are some changes specific to the cloud providers
# for instance we need to encapsulate packets with some network plugins
# If set the possible values are either 'gce', 'aws' or 'openstack'
# When openstack is used make sure to source in the openstack credentials
# like you would do when using nova-client before starting the playbook.
# cloud_provider:
# For multi masters architecture:
# kube-proxy doesn't support multiple apiservers for the time being so you'll need to configure your own loadbalancer
# This domain name will be inserted into the /etc/hosts file of all servers
# configuration example with haproxy :
# listen kubernetes-apiserver-https
# bind 10.99.0.21:8383
# option ssl-hello-chk
# mode tcp
# timeout client 3h
# timeout server 3h
# server master1 10.99.0.26:443
# server master2 10.99.0.27:443
# balance roundrobin
# apiserver_loadbalancer_domain_name: "lb-apiserver.kubernetes.local"
## Set these proxy values in order to update docker daemon to use proxies
# http_proxy: ""
# https_proxy: ""
# no_proxy: ""
## A string of extra options to pass to the docker daemon.
## This string should be exactly as you wish it to appear.
## An obvious use case is allowing insecure-registry access
## to self hosted registries like so:
docker_options: "--insecure-registry={{ kube_service_addresses }}"
