ansible failed_when 字符串包含“fail”或“error”或“fault”不区分大小写

Question

目前我正在使用failed_when: "'failed' in result|lower or 'error' in result|lower or 'fault' in result|lower" 来捕获 ansible 任务的失败情况。编写此条件检查是否有任何failed/error/fault 在返回的win_shell 命令返回状态字符串中的最佳方法是什么？

Answer 1

编写此条件检查是否有任何failed/error/fault 在返回的win_shell 命令返回的状态字符串中的最佳方法是什么？

第一件事：编写正确的 yaml。您最初的问题是简单的语法：

# This a yaml key containing a simple value
a_key: a value

# This is the same value but the string is optionally quoted
other_key: "a value"

# But if you use quotes the string stops at the closing quote
# so the below will fire a parsing error
error_key: "a quoted string" and some garbage chars

# In this case you need disambiguation using other quotes,
# escaping, scalar blocks....
corrected_key1: '"a quoted string" and some garbage chars'
corrected_key2: "\"a quoted string\" and some garbage chars"
corrected_key3: >
  "a quoted string" and some garbage chars
# non exhaustive list

作为第一个修复，我们可以简单地重写您的条件如下：

failed_when: '"failed" in result|lower or "error" in result|lower or "fault" in result|lower'

但是，避免重复搜索词和过滤器以将其转换为小写的更好方法是使用regex 测试：

failed_when: result is regex('^.*(failed|error|fault).*$', ignorecase=true)

根据错误消息的确切模式，可能还有“更好”的方法来编写此条件。
