在ansible中创建RDS

Question

我正在努力为工作学习 ansible。我需要创建 RDS 实例，然后是数据库并获取环境变量。

我总是出错

致命：[本地主机]：失败！ => {"changed": false, "failed": true, "msg": "unsupported parameter for module: register"}

这是我的代码

- name: Configure RDS
  hosts: localhost
  connection: local
  gather_facts: false

  tasks:
    - name: Provision RDS
      rds:
        command: create
        instance_name: ANSIBLEDataloading
        db_engine: Postgresql
        size: 10
        instance_type: sb.m1.small
        username: xxxxx
        password: xxxxx
        tags:
          Environment: Dataloading
          Application: sims
        command: facts
        instance_name: ANSIBLEDataloading
        register: ANSIBLEDataloading
    - name: Add new instance to host group
      add_host: hostname={{ item.endpoint }} groupname=launched_db
      with_items: '{{ANSIBLEDataloading.instance}}'

我正在努力学习，对 ansible 非常陌生。

新代码

- name: Configure RDS
  hosts: localhost
  connection: local
  gather_facts: false

  tasks:
    - name: Provision RDS
      rds:
        command: create
        instance_name: ANSIBLEDataloading
        db_engine: postgres
        region: 'us-east-1'
        size: 10
        instance_type: db.m3.xlarge
        username: xxxxx
        password: xxxx
        tags:
          Environment: Dataloading
          Application: sims
      register: ANSIBLEDataloading
    - name: Add new instance to host group
      add_host: hostname={{ item.endpoint }} groupname=launched_db
      with_items: '{{ANSIBLEDataloading.instance}}'

新错误

fatal: [localhost]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'unicode object' has no attribute 'endpoint'\n\nThe error appears to have been in '/Users/suyesh/Desktop/ansible_conversion/conversion.yml': line 48, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n      register: ANSIBLEDataloading\n    - name: Add new instance to host group\n      ^ here\n"}

您遇到的错误只是格式错误。寄存器应该和任务在同一个缩进。

  tasks:
    - name: Provision RDS
      rds:
        command: create
        instance_name: ANSIBLEDataloading
        db_engine: Postgresql
        size: 10
        instance_type: sb.m1.small
        username: xxxxx
        password: xxxxx
        tags:
          Environment: Dataloading
          Application: sims
        command: facts
        instance_name: ANSIBLEDataloading
      register: ANSIBLEDataloading
