(Kubernetes + Docker) Skaffold 不断终止我的部署文件：错误：无法在 2 分钟内稳定：超出上下文截止日期

Question

我正在尝试使用 Skaffold 在我的本地机器上部署一个微服务系统。

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.dot
      http:
        paths:
          - path: /api/users/?(.*)
            backend:
              serviceName: auth-srv
              servicePort: 3000

auth-depl.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: ****MYDOCKERID****/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-mongo-depl.yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: auth-mongo-depl
spec:
  replicas: 1
  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

我遵循了手册中的指导方针：

https://kubernetes.github.io/ingress-nginx/deploy/

并点击：

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.34.0/deploy/static/provider/cloud/deploy.yaml

然而 Skaffold 不断终止部署：

我们如何解决这个烦人的问题？

Error from server (BadRequest): container "auth" in pod "auth-depl-c6c765d7c-7wvcg" is waiting to start: CreateContainerConfigError

Answer 1

看起来您的auth-depl部署失败了。可能是容器崩溃或出错。要调试，您可以查看 pod 日志

$ kubectl logs auth-depl-xxxxxxxxxx-xxxxx

确保您使用该--cleanup=false选项运行 skaffold，以便您可以进行调试。例如，

$ skaffold dev --cleanup=false

更新：

根据日志，您的 Kubernetes Secret 及其定义方式（可能是格式或 YAML 格式）似乎存在问题。这个答案揭示了可能是什么问题的一些细节：Minikube cluster 中的 Pod status as `CreateContainerConfigError`
