我对Ansible剧本有一个非常奇怪的问题。
我将ansible与Flask API结合使用,因此我使用ansible-runner将变量传递给我的剧本。
我的剧本只是我的字典及其ip属性的调试:
- hosts: localhost
connection: local
any_errors_fatal: no
tasks:
- debug:
msg: '{{ device }}'
- debug:
msg: '{{ device["ip"] }}'
那是我什么都不懂的时候了。我的应用程序位于Docker容器中,这是我启动剧本时遇到的错误:
deploy okay [WARNING]: Unable to parse /etc/ansible/hosts as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note
that the implicit localhost does not match 'all'

除非我在docker之外运行我的剧本,否则没有任何错误,并且我无法在本地或在docker上使用相同版本的python。
你知道那是什么吗?
Ansible 2.7.4
Python 3.5.3
如果您需要更多详细信息,请随时询问。
尝试如下
- debug:
msg: "{{device.ip}}"
您的错误指出:'str object' has no attribute 'ip'
因此您的变量device
是字符串,而不是字典。碰巧这个字符串是json对象的序列化。
您可以使用from_json
filter修复此问题,该操作会将json字符串转换为相应的数据结构。
from_json
然后,您必须找出为什么从本地主机运行时得到正确的json对象,而从docker容器运行时得到json格式的字符串的原因。但这是另一个故事。...
Zeitounator:
您可以使用from_json过滤器来解决此问题,该过滤器将转换您的json字符串转换为相应的数据结构。
- debug: msg: '{{ device | from_json }}' - debug: msg: '{{ (device | from_json)["ip"] }}'
我现在有新的错误消息:
- debug:
msg: '{{ device | from_json }}'
- debug:
msg: '{{ (device | from_json)["ip"] }}'
