我正在尝试启动一堆EC2实例,然后根据AWS给定的IP在它们上安装一些东西。仅使用一个EC2,我就可以添加主机并继续进行而没有任何问题,但是当我使用with_dict链接它们时,我再也无法实现它了...
以下内容可以按我的意愿运行,但是我不明白如何处理从配置中获得的注册变量ec2_infos ...
- name: Create Test EC2 instances
ec2:
group: default
image: ami-40d28157
instance_type: '{{item.value.type}}'
instance_tags:
Name: "{{ tag+'-'+item.value.name }}"
key_name: privatekey
region: us-west-1
vpc_subnet_id: subnet-REDACTD
wait: yes
with_dict: '{{ec2_stack}}'
register: ec2_infos
用像这样的字典
ec2_stack:
serv1:
type: t2.micro
name: server1
serv2:
type: t2.small
name: server2
ec2_infos是类似的结构:

我以不同的方式尝试了with_items和with_subelements,但是我无法设法获得新EC2的每个IP。我什至不需要对它们进行排序,只需将它们从实例部分中提取出来并将它们输入到add_host中,这样我就可以继续。
任何人都知道这样做的干净方法,或者足够友好地向我解释如何在循环后正确处理已注册的变量?
来自评论的答案:
ec2_infos.results | map(attribute='instances') | sum(start=[]) | map(attribute='private_ip') | list
