在 kustomize 中选择性应用名称前缀/名称后缀

目前我们正在使用 ${HOME}/bin/kustomize edit set nameprefix prefix1

但它正在向我们的所有资源（例如，deployment.yaml 和 service.yaml）添加 nameprefix。

我们只想将 nameprefix 应用于deployment.yaml，而不将其应用于service.yaml

发布以获得更好的可见性：

如果您正在使用:

kustomize edit set nameprefix prefix1

该命令将设置名称前缀在你当前的定制化。 正如问题中所述 - 这就是它的工作方式，名称前缀将用于内部所有指定资源自定义.yaml.

请使用以下想法考虑以下场景：overlay and base与定制。

Tested with:
kustomize/v4.0.1

基础声明共享的资源和设置，覆盖声明额外的差异。

.
├── base
│   ├── [deployment.yaml]  Deployment nginx
│   ├── [kustomization.yaml]  Kustomization 
│   └── [service.yaml]  Service nginx
└── prod
    ├── [kustomization.yaml]  Kustomization 
    └── kustomizeconfig
        └── [deploy-prefix-transformer.yaml]  PrefixSuffixTransformer customPrefixer

• base： 共同文件

#deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  selector:
    matchLabels:
      run: nginx

#service.yaml
apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    run: nginx

#kustomization.yaml
resources:
- deployment.yaml
- service.yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

• 覆盖/产品：自定义.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
bases:
- ../../base
nameSuffix: -Suffix1
transformers:
- ./kustomizeconfig/deploy-prefix-transformer.yaml

• 覆盖/产品/kustomizeconfig：部署前缀变压器.yaml

apiVersion: builtin
kind: PrefixSuffixTransformer
metadata:
  name: customPrefixer
prefix: "deploymentprefix-"
fieldSpecs:
- kind: Deployment
  path: metadata/name

正如你所看到的，使用这个结构和内置插件前缀后缀转换器就可以得到想要的效果：

kustomize build overlay/prod/

apiVersion: v1
kind: Service
metadata:
  labels:
    run: nginx
  name: nginx-Suffix1
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: deploymentprefix-nginx-Suffix1
spec:
  selector:
    matchLabels:
      run: nginx

此配置 (overlay/prod/kustomization.yaml) 将适用名称后缀：-后缀1到指定的所有资源base目录和使用前缀后缀转换器 https://kubectl.docs.kubernetes.io/guides/extending_kustomize/builtins/#example-8将在这个具体示例中添加前缀：“deploymentprefix-” to 部署.元数据.名称

apiVersion: builtin
kind: PrefixSuffixTransformer
metadata:
  name: customPrefixer
prefix: "deploymentprefix-"
fieldSpecs:
- kind: Deployment
  path: metadata/name
