我经常不得不做类似的事情，我需要记录各个参数：
- name: foo # ...
module_name: # ...
arg1: 1 # ...
arg2: 2 # ...
bar: "bar" # explanation <---- related
baz: "baz" # explanation <---- related
qux: 42 # ...
如果参数相关，最好将它们分组。
我尝试了所有以下错误的语法：
arg1: 1 # ...
arg2: 2 # ...
bar: "bar" baz:"baz" # explanation
qux: 42 # ...
arg1: 1 # ...
arg2: 2 # ...
bar: "bar", baz: "baz" # explanation
qux: 42 # ...
arg1: 1 # ...
arg2: 2 # ...
bar="bar" baz="baz" # explanation
qux: 42 # ...
我略读了yaml 1.2 reference，但它出奇的复杂。
这可能吗？
但是也许您正在查看的内容可以使用缩写形式（as pointed out here）。
- name: foo # ...
module_name: { # ...
arg1: 1, # ...
arg2: 2, # ...
bar: "bar", baz: "baz", # explanation <---- related
qux: 42 # ...
}
这是由于YAML can be viewed as a natural superset of JSON。演示：
--- - hosts: localhost vars: module_name: # ... arg1: 1 # ... arg2: 2 # ... bar: "bar" # explanation <---- related baz: "baz" # explanation <---- related qux: 42 module_name_alt: { # ... arg1: 1, # ... arg2: 2, # ... bar: "bar", baz: "baz", # explanation <---- related qux: 42 } tasks: - debug: msg: "{{ module_name }}" - debug: msg: "{{ module_name_alt }}"
是否输出：
