创建“STDIN”时出错：运行skaffold dev时发生内部错误

Question

所以，我在ubuntu中使用minikube v1.19.0，在kubernetes中使用nginx ingress。我有两个节点文件：auth和client，分别制作了docker图像

我得到了4个kubernetes-cinfig文件，如下所示：

auth-deply.yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: auth-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: auth
  template:
    metadata:
      labels:
        app: auth
    spec:
      containers:
        - name: auth
          image: xyz/auth
          env:
            - name: JWT_KEY
              valueFrom:
                secretKeyRef:
                  name: jwt-secret
                  key: JWT_KEY
---
apiVersion: v1
kind: Service
metadata:
  name: auth-srv
spec:
  selector:
    app: auth
  ports:
    - name: auth
      protocol: TCP
      port: 3000
      targetPort: 3000

auth-moongo-depl.yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: auth-mongo-depl
spec:
  selector:
    matchLabels:
      app: auth-mongo
  template:
    metadata:
      labels:
        app: auth-mongo
    spec:
      containers:
      - name: auth-mongo
        image: mongo
---
apiVersion: v1
kind: Service
metadata:
  name: auth-mongo-srv
spec:
  selector:
    app: auth-mongo
  ports:
    - name: db
      protocol: TCP
      port: 27017
      targetPort: 27017

客户-depl.yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: client-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: client
  template:
    metadata:
      labels:
        app: client
    spec:
      containers:
        - name: client
          image: xyz/client
---
apiVersion: v1
kind: Service
metadata:
  name: client-srv
spec:
  selector:
    app: client
  ports:
    - name: client
      protocol: TCP
      port: 3000
      targetPort: 3000

ingress-srv.yaml：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-service
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/use-regex: 'true'
spec:
  rules:
    - host: ticketing.dev
      http:
        paths:
          - path: /api/users/?(.*)
            backend:
              serviceName: auth-srv
              servicePort: 3000
          - path: /?(.*)
            backend:
              serviceName: client-srv
              servicePort: 3000

skaffold.yaml：

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

现在，当我运行Skafold dev时，出现了以下错误：

事实上，一切都很好，直到我重新安装minikube，并得到这个问题。这里需要帮助。

Answer 1

您的日志清楚地表明入口版本警告存在问题。

警告：扩展/v1beta1入口在v1.14中被弃用，在v1.22中不可用；使用networking.k8s。io/v1入口

您的群集版本可能高于1.14

这可能是你的minikube的一个可能版本得到了更新

最新入口示例

apiVersion: "networking.k8s.io/v1beta1"
kind: "Ingress"
metadata:
  name: "example-ingress"
spec:
  ingressClassName: "external-lb"
  rules:
  - host: "*.example.com"
    http:
      paths:
      - path: "/example"
        pathType: "Prefix"
        backend:
          serviceName: "example-service"
          servicePort: 80

lastet ingress API版本为：networking.k8s。io/v1beta1您可以检查lubernetes集群的版本，并验证支持哪个API集群。

https://kubernetes.io/blog/2020/04/02/improvements-to-the-ingress-api-in-kubernetes-1.18/

要检查您可以运行库伯内特斯支持的API版本：

kubectl api-versions

Answer 2

事实上，我刚刚发现问题是在重新安装minikube时，验证Webhook没有被删除，因此应该使用以下命令删除创建的问题。

kubectl delete -A ValidatingWebhookConfiguration ingress-nginx-admission

我发现，虽然重新安装我忘了删除这个网络钩子，这是安装在清单，造成这个问题。
