# Directory where the binaries will be installed
bin_dir: /usr/local/bin

## 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: disable peer client cert authentication.
# This affects ETCD_PEER_CLIENT_CERT_AUTH variable

## External LB example config
## apiserver_loadbalancer_domain_name: "elb.some.domain"
#loadbalancer_apiserver:
#  address: 1.2.3.4
#  port: 1234

## Internal loadbalancers for apiservers
#loadbalancer_apiserver_localhost: true

## Local loadbalancer should use this port instead, if defined.
## Defaults to kube_apiserver_port (6443)
#nginx_kube_apiserver_port: 8443

### OTHER OPTIONAL VARIABLES
## For some things, kubelet needs to load kernel modules.  For example, dynamic kernel services are needed
## for mounting persistent volumes into containers.  These may not be loaded by preinstall kubernetes
## processes.  For example, ceph and rbd backed volumes.  Set to true to allow kubelet to load kernel
## modules.
#kubelet_load_modules: false

## Internal network total size. This is the prefix of the
## entire network. Must be unused in your environment.
#kube_network_prefix: 18

## With calico it is possible to distributed routes with border routers of the datacenter.
## Warning : enabling router peering will disable calico's default behavior ('node mesh').
## The subnets of each nodes will be distributed by the datacenter router

## Upstream dns servers used by dnsmasq
#upstream_dns_servers:
#  - 8.8.8.8

## 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', 'azure', 'openstack', 'vsphere', 'oci', or 'external'
## 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:

## When azure is used, you need to also set the following variables.
## see docs/azure.md for details on how to get these values
#azure_tenant_id:
#azure_subscription_id:
#azure_aad_client_id:
#azure_aad_client_secret:
#azure_resource_group:
#azure_location:
#azure_subnet_name:
#azure_security_group_name:
#azure_vnet_name:
#azure_vnet_resource_group:
#azure_route_table_name:

## When OpenStack is used, Cinder version can be explicitly specified if autodetection fails (Fixed in 1.9: https://github.com/kubernetes/kubernetes/issues/50461)
#openstack_blockstorage_version: "v1/v2/auto (default)"
## When OpenStack is used, if LBaaSv2 is available you can enable it with the following 2 variables.
#openstack_lbaas_enabled: True
#openstack_lbaas_subnet_id: "Neutron subnet ID (not network ID) to create LBaaS VIP"
## To enable automatic floating ip provisioning, specify a subnet.
#openstack_lbaas_floating_network_id: "Neutron network ID (not subnet ID) to get floating IP from, disabled by default"
## Override default LBaaS behavior
#openstack_lbaas_use_octavia: False
#openstack_lbaas_method: "ROUND_ROBIN"
#openstack_lbaas_provider: "haproxy"
#openstack_lbaas_create_monitor: "yes"

## When Oracle Cloud Infrastructure is used, set these variables
#oci_private_key:
#oci_region_id:
#oci_tenancy_id:
#oci_user_id:
#oci_user_fingerprint:
#oci_compartment_id:
#oci_vnc_id:
#oci_subnet1_id:
#oci_subnet2_id:
## Overide these default behaviors if you wish
#oci_security_list_management: All
# If oci_use_instance_principals is true, you do not need to set the region, tenancy, user, key, passphrase, or fingerprint
#oci_use_instance_principals: false
#oci_cloud_controller_version: 0.5.0

## Uncomment to enable experimental kubeadm deployment mode
#kubeadm_enabled: false

#https_proxy: ""
## Refer to roles/kubespray-defaults/defaults/main.yml before modifying no_proxy
#no_proxy: ""

## Uncomment this if you want to force overlay/overlay2 as docker storage driver
## Please note that overlay2 is only supported on newer kernels
#docker_storage_options: -s overlay2

# Uncomment this if you have more than 3 nameservers, then we'll only use the first 3.
#docker_dns_servers_strict: false

## Certificate Management
## This setting determines whether certs are generated via scripts or whether a
## cluster of Hashicorp's Vault is started to issue certificates (using etcd
## as a backend). Options are "script" or "vault"
#cert_management: script

# Set to true to allow pre-checks to fail and continue deployment
#ignore_assert_errors: false

## Etcd auto compaction retention for mvcc key value store in hour
#etcd_compaction_retention: 0

## Set level of detail for etcd exported metrics, specify 'extensive' to include histogram metrics.
#etcd_metrics: basic

## Etcd is restricted by default to 512M on systems under 4GB RAM, 512MB is not enough for much more than testing.
## Set this if your etcd nodes have less than 4GB but you want more RAM for etcd. Set to 0 for unrestricted RAM.
#etcd_memory_limit: "512M"

## Etcd has a default of 2G for its space quota. If you put a value in etcd_memory_limit which is less than
## etcd_quota_backend_bytes, you may encounter out of memory terminations of the etcd cluster. Please check
## etcd documentation for more information.
#etcd_quota_backend_bytes: "2G"
