Question

我是Ansible的新手，我正努力从寄存器变量ec2中获取字典值。这是我的戏

---
 - name: Provision 2 bastions in different AZ
   hosts: local
   connection: local
   gather_facts: True
   vars_files:
    - /home/marco/project_provision/bastion_vars.yml

tasks:

  - name: Launch the new EC2 Instance
    with_items: "{{ subnets }}"
    local_action: ec2 
                  group_id={{ security_group }} 
                  instance_type={{ instance_type}} 
                  image={{ image }} 
                  wait=true 
                  region={{ region }} 
                  keypair={{ keypair }}
                  count={{count}}
                  vpc_subnet_id={{ item.vpc_pvt_subnet }}
                  zone={{ item.zone }}
    register: ec2

  - name: debug
    debug: var=ec2

  - name: Add the newly created EC2 instance(s) to the local host group 
    local_action: lineinfile 
                  dest="/home/marco/safeboda_provision/hosts" 
                  regexp={{ item.public_ip }} 
                  insertafter="[bastion]" line={{ item.public_ip }}
    with_dict: "{{ ec2.instances }}"

  - name: Wait for SSH to come up
    local_action: wait_for 
                  host={{ item.public_ip }} 
                  port=22 
                  state=started
    with_items: "{{ ec2.instances }}"

实例创建正确，但是当我尝试对其进行标记或将其动态添加到清单中时，我得到的结果就是

TASK [Add the newly created EC2 instance(s) to the local host group] ****************************************************
fatal: [localhost]: FAILED! => {"msg": "'dict object' has no attribute 'instances'"}
to retry, use: --limit @/home/marco/project_provision/create_ec2_bastions.retry

这是上一条命令的调试输出

                    "image_id": "ami-0b8401ca902dbfbb9",

有人可以阐明我如何遍历任务返回的值吗？
