# For some environments, each node has a pubilcally accessible

# 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

# Etcd access modes:
# Enable multiaccess to configure clients to access all of the etcd members directly

# 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).
