Ansible动态库存无法获取最新的ec2信息

我正在使用ec2.py动态库存进行ansible设置。我已将文件放置ec2.py在/etc/ansible/hosts文件中并标记为可执行文件。我也有ec2.ini档案/etc/ansible/hosts。

[ec2]

regions = us-west-2
regions_exclude = us-gov-west-1,cn-north-1


destination_variable = public_dns_name

vpc_destination_variable = ip_address
route53 = False

all_instances = True
all_rds_instances = False


cache_path = ~/.ansible/tmp

cache_max_age = 0

nested_groups = False
group_by_instance_id = True
group_by_region = True
group_by_availability_zone = True
group_by_ami_id = True
group_by_instance_type = True
group_by_key_pair = True
group_by_vpc_id = True
group_by_security_group = True
group_by_tag_keys = True
group_by_tag_none = True
group_by_route53_names = True
group_by_rds_engine = True
group_by_rds_parameter_group = True

以上是我的ec2.ini档案

---
- hosts: localhost
  connection: local
  gather_facts: yes
  vars_files:
   - ../group_vars/dev_vpc
   - ../group_vars/dev_sg
   - ../hosts_vars/ec2_info
  vars:
    instance_type: t2.micro
  tasks:
   - name: Provisioning EC2 instance
     local_action:
     module: ec2
     region: "{{ region }}"
     key_name: "{{ key }}"
     instance_type: "{{ instance_type }}"
     image: "{{ ami_id }}"
     wait: yes
     group_id: ["{{ sg_npm }}", "{{sg_ssh}}"]
     vpc_subnet_id: "{{ PublicSubnet }}"
     source_dest_check: false
     instance_tags: '{"Name": "EC2", "Environment": "Development"}'
 register: ec2
  - name: associate new EIP for the instance
    local_action:
      module: ec2_eip
      region: "{{ region }}"
      instance_id: "{{ item.id }}"
      with_items: ec2.instances
  - name: Waiting for NPM Server to come-up
    local_action:
      module: wait_for
      host: "{{ ec2 }}"
      state: started
      delay: 5
      timeout: 200
 - include: ec2-configure.yml

现在配置脚本如下

- name: Configure EC2 server
  hosts: tag_Name_EC2
  user: ec2-user
  sudo: True
  gather_facts: True
  tasks:
   - name: Install nodejs related packages
     yum: name={{ item }} enablerepo=epel state=present
     with_items:
      - nodejs
      - npm

但是，调用configure脚本时，第二个脚本导致找不到主机。如果我一个人执行，ec2-configure.yml并且EC2服务器已启动并正在运行，那么它就能找到并配置它。

我添加了wait_for，以确保实例在ec2-configure.yml调用之前处于运行状态。

如果有人能指出我的错误，将不胜感激。谢谢
