Ansible実践ガイド 4-2のKeepalivedの起動確認のタスクは、portを指定しないとtaimuautoまで待ってしまうのではないか？それにlocal_actionのwait_forではbecomeは不要なのでは。 https://gitlab.com/shkitayama/ansible_practical_guide/blob/master/effective_ansible/sec4/roles/keepalived/tasks/configure.yml#L38

configure.yml

- name: configure / Wait for keepalived reload
  become: no
  local_action:
    module: wait_for
    host: "{{ item.address }}"
    port: "{{ item.port }}"
    delay: 5
    timeout: 60
  with_items: "{{ keepalived_vip_interfaces }}"
  run_once: True
