Question

我有一个文件，在该文件中我想添加模式：

dogstreams: /root/ddmonitor/pattern.txt:/opt/datadog-agent/agent/checks/libs/parsers.py:parse_web

到文件的末尾。

到目前为止，我已尝试过以下内容：

---

- name: Creates directory
  file: path=/root/ddmonitor state=directory owner=root group=root mode=0775

- name: copy the pattern_search.txt file which has patterns to be grepped
  copy: src=pattern_search.txt dest=/root/ddmonitor/pattern_search.txt owner=root group=root mode=755

- name: copy the logsearchtest.sh script which greps patterns and prints pattern.txt file
  copy: src=logsearchtest.sh dest=/root/ddmonitor/logsearchtest.sh owner=root group=root mode=755

- name: schedule cron to run every 5 minutes
  cron: name="logsearch script for grepping pega alert logs" minute="*/5" job="/root/ddmonitor/logsearchtest.sh > /dev/null"

- name: copy parsers.py fucntion to datadog lib path
  copy: src=parsers.py dest=/opt/datadog-agent/agent/checks/libs/parsers.py owner=root group=root mode=755

- name: copy datadog agent configuration file
  lineinfile: dest=/etc/dd-agent/datadog.conf regexp="^dogstreams: " line="dogstreams: /root/ddmonitor/pattern.txt:/opt/datadog-agent/agent/checks/libs/parsers.py:parse_web"

- name: wait a bit
  service: name=datadog-agent state=restarted
  when: not datadog_api_key == 'NONE'

但是当我运行我的主剧本时，它会显示以下错误：

ERROR! Syntax Error while loading YAML.

The error appears to have been in '/etc/ansible/roles/datadog-pegalogs-apptier/tasks/main.yml': line 19, column 65, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

- name: copy datadog agent configuration file
  lineinfile: dest=/etc/dd-agent/datadog.conf regexp="dogstreams: " line="dogstreams: /root/ddmonitor/pattern.txt:/opt/datadog-agent/agent/checks/libs/parsers.py:parse_web"
                                                                ^ here
We could be wrong, but this one looks like it might be an issue with
unbalanced quotes.  If starting a value with a quote, make sure the
line ends with the same set of quotes.  For instance this arbitrary
example:

    foo: "bad" "wolf"

Could be written as:

    foo: '"bad" "wolf"'

查看Ansible Docs

我相信你需要做类似的事情：

由于行上的'：'而完全引用。请参阅YAML文档中的Gotchas。

- lineinfile: "dest=/etc/sudoers state=present regexp='^%wheel' line='%wheel ALL=(ALL) NOPASSWD: ALL'"

对于列出here

的“：”存在YAML限制

您需要使用冒号引用任何哈希值，如下所示：

foo: "somebody said I should put a colon here: so I did"

所以你的行应该是这样的：

- name: copy datadog agent configuration file
  lineinfile: "dest=/etc/dd-agent/datadog.conf regexp='^dogstreams: ' line='dogstreams: /root/ddmonitor/pattern.txt:/opt/datadog-agent/agent/checks/libs/parsers.py:parse_web'"

我猜你可以像{{“：”}}那样逃过冒号：

lineinfile: dest=/etc/dd-agent/datadog.conf regexp="^dogstreams{{ ":" }} " line="dogstreams: /root/ddmonitor/pattern.txt{{ ":" }}/opt/datadog-agent/agent/checks/libs/parsers.py:parse_web"

ansible lineinfile选项抛出错误
