Ansible 模块参数语法
为什么要执行的命令任务下的playbook.yml上，有的模块有引号，有的模块没有？
例如，如果您检查下面的语法，模块 line 嵌入在引号中，但 script 则没有。
- name: 'Execute a script on all web server nodes and start httpd service'
hosts: web_nodes
tasks:
- name: 'Update entry into /etc/resolv.conf'
lineinfile:
path: /etc/resolv.conf
line: 'nameserver 10.1.250.10'
- name: 'Execute a script'
script: /tmp/install_script.sh
Why is it that on the playbook.yml under the command task to be executed, some modules have a quotation mark while some does not?
For example, if you check the syntax below, the module line is with embedded in a quotation mark but script is not.
- name: 'Execute a script on all web server nodes and start httpd service'
hosts: web_nodes
tasks:
- name: 'Update entry into /etc/resolv.conf'
lineinfile:
path: /etc/resolv.conf
line: 'nameserver 10.1.250.10'
- name: 'Execute a script'
script: /tmp/install_script.sh

两个模块均采用
line 的参数或cmd一个字符串。您的问题是关于 YAML 语法
何时引用< /a> 和 YAML 陷阱
风格指南也可能是何时以及如何引用不同方式的原因。
Both modules take as parameter for
lineorcmda string.Your question is about the YAML Syntax
when to quote and YAML Gotchas
Also a style guide can be a reason of different ways of when and how to quote.
