使用generateName字段在kubernetes中创建自定义资源 [英] create a custom resource in kubernetes using generateName field

问题描述

我有一个示例crd定义为

I have a sample crd defined as

crd.yaml

kind: CustomResourceDefinition
metadata:
  name: testconfig.demo.k8s.com
  namespace: testns
spec:
  group: demo.k8s.com
  versions:
    - name: v1
      served: true
      storage: true
  scope: Namespaced
  names:
    plural: testconfigs
    singular: testconfig
    kind: TestConfig

我想基于上述crd创建一个自定义资源，但是我不想为该资源分配一个固定的名称，而是使用generateName字段.所以我生成了以下cr.yaml.但是当我应用它时，错误提示名称字段为必填

I want to create a custom resource based on above crd but i dont want to assign a fixed name to the resource rather use the generateName field. So i generated the below cr.yaml. But when i apply it gives error that name field is mandatory

kind: TestConfig
metadata:
  generateName: test-name-
  namespace: testns
spec:
  image: testimage

我们非常感谢您的帮助.

Any help is highly appreciated.

推荐答案

您应使用kubectl create和generateName创建CR.

"kubectl apply将在执行操作之前验证资源是否存在.如果资源不存在，则会首先创建它们.如果使用generateName，则在验证资源是否存在时尚未生成资源名称.资源." 来源

"kubectl apply will verify the existence of the resources before take action. If the resources do not exist, it will firstly create them. If use generateName, the resource name is not yet generated when verify the existence of the resource." source
