希望对您有所帮助。一旦你有了 instance id 然后你可以做任何你想做的事，我只是将它从 ELB 中删除但是你可以使用 ec2 模块来删除它。

  connection: local
  gather_facts: no
  tasks:
   - name: Get the facts about the ELB
     ec2_elb_facts:
       names: rbgeek-dev-web-elb
       region: "eu-west-1"
     register: elb_facts

   - name: Instance(s) ID that are currently register to the ELB
     debug:
       msg: "{{ elb_facts.elbs.0.instances }}"

   - name: Tag the Old instances as zombie
     ec2_tag:
       resource: "{{ item }}"
       region: "eu-west-1"
       state: present
       tags:
         Instance_Status: "zombie"
     with_items: "{{ elb_facts.elbs.0.instances }}"
