# This inventory is auto-generated by 'make generate'
# See https://docs.ansible.com/ansible/latest/inventory_guide/intro_inventory.html
# for tips on building your inventory

# ⚠️ IMPORTANT: Node naming convention
# Each node name must start with the domain name prefix (<domain-name>-) followed by the role:
# - Control Plane Nodes: <domain-name>-control-plane-X[-etcd][-worker] (where X is the index: 0, 1, 2, etc.)
# - ETCD Nodes: <domain-name>-etcd-X (where X is the index: 0, 1, 2, etc.)
# - Worker Nodes: <domain-name>-worker-X[-etcd] (where X is the index: 0, 1, 2, etc.)
#
# ⚠️ WARNING: DO NOT change the first control plane node (<domain-name>-control-plane-0) without understanding
# the implications! See README.md for more details on the proper procedure for replacing
# the first control plane node.

# Configure 'ip' variable to bind kubernetes services on a different ip than the default iface
# We should set etcd_member_name for etcd cluster. The node that are not etcd members do not need to set the value,
# or can set the empty string value.
