【发布时间】：2021-11-14 00:50:59
【问题描述】：

我正在开发由 docker、kubernetes 和 skaffold 开发的微服务应用程序这是我的 skaffold 配置文件

apiVersion: skaffold/v2alpha3
kind: Config
deploy:
  kubectl:
    manifests:
      - ./infra/k8s/*
build:
  local:
    push: false
  artifacts:
    - image: mohamedl3zb/auth
      context: auth
      docker:
        dockerfile: Dockerfile
      sync:
        manual:
          - src: "src/**/*.ts"
            dest: .
    - image: mohamedl3zb/tickets
      context: tickets
      docker:
        dockerfile: Dockerfile
      sync:
        manual:
          - src: "src/**/*.ts"
            dest: .

我收到此错误

我正在使用 docker 桌面和 kubernetes

【问题讨论】：

看起来像是错字：unknown field \"fielsRef\"
我已经修复了它，但仍然给我这个错误
所以不固定？
您的 Kubernetes 清单中似乎存在许多验证错误。免费的 Google Cloud Shell Editor (ide.cloud.google.com) 提供 Kubernetes 清单验证并与 Skaffold 集成。通过 Cloud Code (cloud.google.com/code) 扩展（也是免费的），此支持也可用于 VS Code 和 IntelliJ。

【解决方案1】：

您的清单中有两个拼写错误被准入控制器拒绝。

第一个是nats-depl.yaml，其中Deployment 拼写错误。

您提到的第二个已经在评论中修复，但为了完整起见，我将在此处留下错误的相关部分：

"C:\\\\Users\\\\Mohamed Salah\\\\Desktop\\\\ticket-app\\\\infra\\\\k8s\\\\tickets-depl.yaml\": error validating data: ValidationError(Deployment.spec.template.spec.containers[0].env[4].valueFrom): unknown field \"fielsRef\" in io.k8s.api.core.v1.EnvVarSource

【讨论】：

修复了它，但仍然给我同样的错误
如果您仍然收到与拼写错误完全相同的错误。您可能应该仔细检查确切的错误消息，因为清单文件可能存在其他问题，这些问题会产生类似错误但输出略有不同。该消息应该非常明确地说明问题所在的位置，就像之前的错误一样。

【解决方案2】：

错误似乎是这样 “io.k8s.api.core.v1.EnvVarSource 中的未知字段“fielsRef””
