我之前的任务是创建每周备份,并使用服务器名称后跟日期/时间标记对其进行标记。这项工作的目标是进入后面并清理旧的AMI备份,只留下最后的3. ec2_ami_find
任务正常,但它也可能返回一些服务器的空结果,我想处理该问题的注销任务。
我得到的错误非常通用:
致命:[127.0.0.1]:失败! => { “失败”:是的, “msg”:“条件检查'item.ec2_ami_find.exists'失败。错误是:评估条件时出错 (item.ec2_ami_find.exists):'dict object'没有属性 'ec2_ami_find'\ n \ n错误似乎已经出现了 '/root/ansible/ec2-backups-purge/roles/first_acct/tasks/main.yml':第25行, 第3列,但可能在文件的其他位置,具体取决于具体情况 语法问题。\ n \ n违规行似乎是:\ n \ n \ n-名称: 取消注册旧备份\ n ^ here \ n“
剧本任务内容如下:
---
- name: Find old backups
tags: always
ec2_ami_find:
owner: self
aws_access_key: "{{ access_key }}"
aws_secret_key: "{{ secret_key }}"
region: "{{ aws_region }}"
ami_tags:
Name: "{{ item }}-weekly-*"
sort: name
sort_order: descending
sort_start: 3
with_items:
- server-01
- server-02
- server-win-01
- downloads
register: stale_amis
- name: Deregister old backups
tags: always
ec2_ami:
aws_access_key: "{{ access_key }}"
aws_secret_key: "{{ secret_key }}"
region: "{{ aws_region }}"
image_id: "{{ item.ami_id }}"
delete_snapshot: True
state: absent
with_items:
- "{{ stale_amis.results }}"
其中一个结果的片段返回:

答案 0 :(得分:2)
我怀疑你的尝试:
with_items:
- "{{ stale_amis.results }}"
因为ec2_ami_find
将结果放入自己的results
字段中。因此,第一台服务器的第一个AMI将是stale_amis.results[0].results[0].ami_id
我建议将原始stale_amis
缩减为必需列表并将其循环。例如,您可以使用json_query
过滤器:
- ec2_ami:
aws_access_key: "{{ access_key }}"
aws_secret_key: "{{ secret_key }}"
region: "{{ aws_region }}"
image_id: "{{ item }}"
delete_snapshot: True
state: absent
with_items: "{{ stale_amis | json_query('results[].results[].ami_id') }}"
