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。

入口-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

我已按照手册中的指南进行操作：

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 继续终止部署：

我们如何解决这个烦人的问题？

看起来您的auth-depl部署失败了。可能容器正在崩溃或出错。要调试，您可以查看 pod 日志

$ kubectl logs auth-depl-xxxxxxxxxx-xxxxx

确保使用该--cleanup=false选项运行 skaffold，以便进行调试。例如，

$ skaffold dev --cleanup=false

更新：

根据日志，您的 Kubernetes Secret 及其定义方式可能存在问题，可能是格式或 YAML 格式。这个答案揭示了问题可能是什么的一些细节：Pod status as `CreateContainerConfigError` in Minikube cluster

您应该在部署文件中添加 mongo 映像的环境变量

 env:
        - name: MONGO_INITDB_ROOT_USERNAME
          value: root
        - name: MONGO_INITDB_ROOT_PASSWORD
          value: "rootuser"
