    # Note that availability zones can be omitted when using custom launch
    # templates that contain either pre-configured availability zones or custom
    # network interfaces for all node types, since each node will always be
    # launched in either the launch template's AZ or the AZ shared by its
    # network interface subnets.
    # If some of your node types have launch templates binding them to AZs and
    # others do not, then node types without AZ bindings will be limited to
    # launching only in subnets available in the below availability zones:
    availability_zone: us-west-2a, us-west-2b, us-west-2c
