我使用 Minikube 来模拟我的 Kubernetes 生产架构。 在集群中，我需要创建一个网站，我决定使用 Sails.js。

这是我的 Kubernetes 配置：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: white-label-storage-persistent-volume
  labels:
    type: local
    app: white-label
    role: master
    tier: backend
spec:
  storageClassName: manual
  capacity:
    storage: 5Gi
  accessModes:
  - ReadWriteMany
  hostPath:
    path: "/white-label-data"
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: white-label-storage-persistent-volume-claim
  labels:
    app: white-label
    role: master
    tier: backend
spec:
  storageClassName: manual
  accessModes:
  - ReadWriteMany
  resources:
    requests:
      storage: 5Gi
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: white-label-deployment
  labels:
    app: white-label
    role: master
    tier: backend
spec:
  replicas: 1
  strategy:
    type: RollingUpdate
  selector:
    matchLabels:
      app: white-label
      role: master
      tier: backend
  template:
    metadata:
      labels:
        app: white-label
        role: master
        tier: backend
    spec:
      containers:
      - name: white-label
        image: pastel-white-label:v1
        imagePullPolicy: IfNotPresent
        workingDir: "/usr/src/app"
        resources:
          requests:
            memory: 2Gi
            cpu: 1
          limits:
            memory: 4Gi
            cpu: 2
        ports:
        - containerPort: 1337
          protocol: TCP
        volumeMounts:
        - mountPath: "/data"
          name: white-label-persistent-volume
      volumes:
        - name: white-label-persistent-volume
          persistentVolumeClaim:
            claimName: white-label-storage-persistent-volume-claim
---
apiVersion: v1
kind: Service
metadata:
  name: white-label-service
  labels:
    app: white-label
    role: master
    tier: backend
spec:
  type: LoadBalancer
  ports:
  - port: 1337
    protocol: TCP
    nodePort: 30003
  selector:
    app: white-label
    role: master
    tier: backend
  sessionAffinity: None
---
apiVersion: autoscaling/v1
kind: HorizontalPodAutoscaler
metadata:
  name: white-label-hpa
  labels:
    app: white-label
    role: master
    tier: backend
  namespace: default
spec:
  maxReplicas: 5
  minReplicas: 1
  scaleTargetRef:
    apiVersion: extensions/v1
    kind: Deployment
    name: white-label-deployment
  targetCPUUtilizationPercentage: 80

这是 pastel-white-label:v1 Docker 镜像：

FROM node:10.13.0-stretch

WORKDIR /usr/src/app
COPY . ./

RUN npm install -g sails npm-check-updates
RUN npm install @sailshq/connect-redis --save
RUN npm install

CMD ["sails", "lift"]

当我启动集群并构建 pod 时，一切都运行良好。 我的 Sails.js 日志一尘不染，我可以在浏览器中看到主页：完全没有问题。顺便说一句，我在 Web 应用模式下使用 Sails.js v1.1.0。我还可以看到 Grunt 已启动并正在监视。

现在，如果我编辑 .less 文件，则会得到不友好的结果：

debug: -------------------------------------------------------
error: ** Grunt :: An error occurred. **
error: 
------------------------------------------------------------------------

Aborted due to warnings.
Running "watch" task
Waiting...
>> File "assets/styles/styleguide/colors.less" changed.
Loading "sync.js" tasks...ERROR
>> TypeError: Cannot read property 'length' of undefined
Warning: Task "sync:dev" not found.

我确定我的 .less 文件没有错误（十六进制代码版本），我的 .tmp 文件夹是可写的（例如，touch .tmp/foo 正在工作），并且我相信 Grunt 已正确安装，因为它是开箱即用的……

那么我真的不知道这里发生了什么……

你们有什么想法吗？

提前谢谢大家
