seb*_*ini 5 yaml ansible ansible-2.x
我在 Ansible playbook 中有一个任务,该任务应该迭代用户列表并执行 lineinfile 以启用对 postgress 数据库的访问:
- name: Postgres localhost access
lineinfile:
dest: "{{postgres_dest}}/data/pg_hba.conf"
line: "host all {{item.user}} 127.0.0.1/32 trust"
regexp: "^host[\s\t]*all[\s\t]*{{item.user}}[\s\t]*127.0.0.1/32[\s\t]*trust"
insertbefore: EOF
with_items: "{{postgres_users}}"
notify: postgres reload
tags:
- postgres
- postgres_hba

我遇到的问题是 ansible 认为{{item.user}}没有被 转义"",这实际上是不正确的,因为这会由于""整行的扩大。我得到的确切错误:
Syntax Error while loading YAML script, jenkins.yml
Note: The error may actually appear before this position: line 156, column 9
line: "host all {{item.user}} 127.0.0.1/32 trust"
regexp: "^host[\s\t]*all[\s\t]*{{item.user}}[\s\t]*127.0.0.1/32[\s\t]*trust"
^
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"

关于如何做到这一点的任何想法?
首先,感谢#ansible 频道上 IRC 的那些人:)
似乎问题不在于 vars 本身,而在于 un-scaped 反斜杠
将行更改为:
regexp: "^host[\\s\\t]*all[\\s\\t]*{{item.user}}[\\s\\t]*127.0.0.1/32[\\s\\t]*trust"
现在效果很好
