kubevirt通过json patch 关闭,启动虚拟机

JSON Patch由IETF在RFC 6902中规范.JavaScript Object Notation (JSON) Patch

JSON Path是描述JSON文档变化的格式. 使用它可以避免在只需要修改某一部分的时候发送整个文档内容. 当与HTTP PATCH方法混合使用的时候, 它允许在标准规范的基础上使用HTTP APIs进行部分更新.

   A JSON Patch document is a JSON [RFC4627] document that represents an
   array of objects.  Each object represents a single operation to be
   applied to the target JSON document.

   The following is an example JSON Patch document, transferred in an
   HTTP PATCH request:

   PATCH /my/data HTTP/1.1
   Host: example.org
   Content-Length: 326
   Content-Type: application/json-patch+json
   If-Match: "abc123"

   [
     { "op": "test", "path": "/a/b/c", "value": "foo" },
     { "op": "remove", "path": "/a/b/c" },
     { "op": "add", "path": "/a/b/c", "value": [ "foo", "bar" ] },
     { "op": "replace", "path": "/a/b/c", "value": 42 },
     { "op": "move", "from": "/a/b/c", "path": "/a/b/d" },
     { "op": "copy", "from": "/a/b/d", "path": "/a/b/e" }
   ]

Kubectl 日志输出详细程度

kubectl 备忘单

Kubectl 日志输出详细程度是通过 -v 或者 –v 来控制的，参数后跟一个数字表示日志的级别。

详细程度	描述
–v=0	用于那些应该始终对运维人员可见的信息，因为这些信息一般很有用。
–v=1	如果您不想要看到冗余信息，此值是一个合理的默认日志级别。
–v=2	输出有关服务的稳定状态的信息以及重要的日志消息，这些信息可能与系统中的重大变化有关。这是建议大多数系统设置的默认日志级别。
–v=3	包含有关系统状态变化的扩展信息。
–v=4	包含调试级别的冗余信息。
–v=5	跟踪级别的详细程度。
–v=6	显示所请求的资源。
–v=7	显示 HTTP 请求头。
–v=8	显示 HTTP 请求内容。
–v=9	显示 HTTP 请求内容而且不截断内容。
