Kubectl 支持 JSONPath 模板。

JSONPath template is composed of JSONPath expressions enclosed by curly braces {}.
Kubectl uses JSONPath expressions to filter on specific fields in the JSON object and format the output.
In addition to the original JSONPath template syntax, the following functions and syntax are valid:

JSONPath 模板由 {} 包起来的 JSONPath 表达式组成。Kubectl 使用 JSONPath 表达式来过滤 JSON 对象中的特定字段并格式化输出。除了原始的 JSONPath 模板语法，以下函数和语法也是有效的:
<!--
<!--
1. Use double quotes to quote text inside JSONPath expressions.
2. Use the `range`, `end` operators to iterate lists.
3. Use negative slice indices to step backwards through a list. Negative indices do not "wrap around" a list and are valid as long as `-index + listLength >= 0`.

1. 使用双引号将 JSONPath 表达式内的文本引起来。
2. 使用 `range`，`end` 运算符来迭代列表。
3. 使用负片索引后退列表。负索引不会“环绕”列表，并且只要 `-index + listLength> = 0` 就有效。

- The `$` operator is optional since the expression always starts from the root object by default.
- The result object is printed as its String() function.

- `$` 运算符是可选的，因为默认情况下表达式总是从根对象开始。

On Windows, you must _double_ quote any JSONPath template that contains spaces (not single quote as shown above for bash). This in turn means that you must use a single quote or escaped double quote around any literals in the template. For example:
