尝试使用Ansible对服务器上的文件(websocket.py)中的几行进行注释,但由于某些原因,我的代码在OPCODE_CONTINUATION之前没有添加第二个注释块。
想法是在“slot”行之前添加三行引号,在“OPCODE_CONTINUATION”行之前添加三个引号。我当前的解决方案试图找到具有正则表达式的行,但显然有些错误,因为只添加了第一个注释块。
Ansible版本2.0.1.0(2016/02/22 11:04:54)
websocket.py的片段:
__slots__ = ('utf8validator', 'utf8validate_last', 'environ', 'closed',
'stream', 'raw_write', 'raw_read', 'handler')
OPCODE_CONTINUATION = 0x00
Ansible playbooks脚本:
---
- name: First comment
blockinfile:
dest: /usr/local/lib/python2.7/site-packages/geventwebsocket/websocket.py
insertbefore: '\w{9}\s\W\s\W{2}\w{13}'
state: present
block: |
"""
- name: Second comment
blockinfile:
dest: /usr/local/lib/python2.7/site-packages/geventwebsocket/websocket.py
insertbefore: '\s{4}\w{19}\s\W\s\d\w\d\d'
state: present
block: |
"""
结果
# BEGIN ANSIBLE MANAGED BLOCK
"""
# END ANSIBLE MANAGED BLOCK
__slots__ = ('utf8validator', 'utf8validate_last', 'environ', 'closed',
'stream', 'raw_write', 'raw_read', 'handler')
OPCODE_CONTINUATION = 0x00
文件:Websocket.py

标记是blockinfile
模块的主要标识符。请参阅docs中的marker
选项。
制作者默认为# {mark} ANSIBLE MANAGED BLOCK
,这是您在修改后的文件中看到的内容。在第二个任务Ansible在文件中找到那些确切的标记并假定该块存在。
如果您在每个任务上提供唯一标记,它应该有效:
- name: First comment
blockinfile:
dest: /usr/local/lib/python2.7/site-packages/geventwebsocket/websocket.py
insertbefore: '\w{9}\s\W\s\W{2}\w{13}'
state: present
marker: "# {mark} FIRST COMMENT"
block: ' """'
- name: Second comment
blockinfile:
dest: /usr/local/lib/python2.7/site-packages/geventwebsocket/websocket.py
insertbefore: '\s{4}\w{19}\s\W\s\d\w\d\d'
state: present
marker: "# {mark} SECOND COMMENT"
block: ' """'
