|
||||
|
||||
目标字段指向的 kubernetes 对象的 group、 version、 kind、 name 和 namespace 在同一 kustomization 内 path 字段内容是 JSON patch 文件的相对路径。
|
||||
|
||||
patch 文件中的内容可以如下这种 JSON 格式:

||||
```
|
||||
[
|
||||
{"op": "add", "path": "/some/new/path", "value": "value"},

|
||||
]
|
||||
```
|
||||
|
||||
也可以使用 YAML 格式表示:
|
||||
|
||||
```
|
||||
- op: add
|
||||
path: /some/new/path
|
||||
value: value
|

||||

||||
name: deployment-name
|
||||
spec:

||||
replicas: 3

||||
```
|
||||
|
||||
在 kustomization 中添加以下内容,将副本数更改为5:
|
||||
|
||||
```
|
||||
replicas:
|
||||
- name: deployment-name
|
||||
count: 5
|
||||
```
|
||||
|
||||
该字段内容为列表,所以可以同时修改许多资源。

||||

||||
#### Limitation
|
||||
|
||||
由于这个声明无法设置 `kind:` 或 `group:` 它将匹配任何可以匹配名称的 `group` 和 `kind` ,并且它是以下之一:
|
||||
- `Deployment`
|
||||
- `ReplicationController`
|

||||
- `StatefulSet`

// Functions are implemented as a go function which accept a slice of resources (items)
|
||||
// and returns a modified slice of resources (items).
|
||||
// Functions modify a slice of resources (ResourceList.items) which are read as input and written
|
||||
// as output. The function itself may be configured through a functionConfig
|

// (ResourceList.functionConfig).

//

// Example Function Input:

//
|

// kind: ResourceList

// items:

// - kind: Deployment
|

// ...

// functionConfig:

// kind: Example
|

// spec:
|

// value: foo
|

//
|

// The functionConfig may be specified declaratively and run with

||||
//
|
||||
// config run DIR/

// Declarative function declaration:
|

//
|

// kind: Example

// metadata:

// annotations:

// # run the function by creating this container and providing this

// The framework takes care of serializing and deserializing the ResourceList.
|
||||
//
|
||||
// Generated ResourceList.functionConfig -- ConfigMaps
|
||||
//
|
||||
// Functions may also be specified imperatively and run using:
|
||||
//
|
||||
// config run DIR/ --image image/containing/fuction:impl -- value=foo

// To write a function that can be run imperatively on the commandline, have it take a

// ConfigMap as its functionConfig.

// Mutator and Generator Functions

// When using framework.ResourceList this is done through modifying ResourceList.Items in place.
|
||||
//
|
||||
// Validator Functions
|
||||
//
|
||||
// Functions may validate resources, returning Results as go errors. Results may contain

// different items for different validation failures.
|

// A function may validate resources by providing a Result.

// When using framework.Command this is done through returning a framework.Result as an error.

// Configuring Functions
|

// Functions may be configured through a functionConfig (i.e. a client side custom resource),
|
||||
// or through flags (which the framework parses from a ConfigMap provided as input).
|
||||
// Any flags registered on the cobra.Command will be parsed from the functionConfig input
|
||||
// if they are defined as functionConfig.data entries.

// ContainerFilter applies the function only to Resources to which it is scoped.

// Resources are scoped to a function if any of the following are true:

// - the Resource were read from the same directory as the function config

// - the Resource were read from a subdirectory of the function config directory

// - the function config doesn't have a path annotation (considered globally scoped)
