Question

尝试创建一个剧本，让我选择是否要通过传递外部变量来实现即期或按需EC2，除了从结果中获取专用ip并将其设置为进一步使用的部分之外，其他一切都很好。

我尝试了不同的路径，例如item.instances [0] .private_ip 似乎无法找到合适的人。

- hosts: localhost
  tasks:
  - name: when true
    ec2:
      region: us-east-1
      instance_type: t2.nano
      key_name: test_key
      instance_type: t2.micro
      image: ami-0aec0138b2*****
      wait: yes
      count: 1
      vpc_subnet_id: subnet-00fdda1452d****
      assign_public_ip: no
      spot_price: 1
    register: ci_ec2_true
    when: var == "true"


  - name: when false
    ec2:
      region: us-east-1
      instance_type: t2.nano
      key_name: test_key
      instance_type: t2.micro
      image: ami-0aec0138b2****
      wait: yes
      count: 1
      vpc_subnet_id: subnet-00fdda1452d0****
      assign_public_ip: no
    register: ci_ec2_false
    when: var == "false"



  - name: ci_ec2_true
    debug:
      msg: "{{ ci_ec2_true }}"

  - name: Spot / On-demand var router
    set_fact:
      ci_ec2: "{{ ci_ec2_true if ci_ec2_false is skipped else ci_ec2_false }}"


  - name: debug ci_ec2
    debug:
      msg: "{{ ci_ec2 }}"

  - name: ec2_prov - set fact for all ci_machine_ips
    set_fact: private_ips="{{ item.instances[0].private_ip }}"
    with_items: "{{ ci_ec2 }}"
    register: ci_ec2_ip_results

  - debug:
      msg: "{{ ci_ec2_ip_results }}"

预期结果应该是私有ip值，而不是我收到此错误：

TASK [ec2_prov - set fact for all ci_machine_ips] ******************************
**********
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: 'ansible.vars.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'instances'\n\nThe error appears to have been in '/root/test/when-create.yml': line 50, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n  - name: ec2_prov - set fact for all ci_machine_ips\n    ^ here\n"}

用于运行剧本的命令是：

ansible-playbook when-create.yml -e var=true

TASK [debug ci_ec2] ************************************************************
