node.js - Kubernetes Node.js 容器不断崩溃

Question

我正在尝试使用以下 YAML 创建一个 Pod，特别是在 Google Cloud Platform 上:

apiVersion: v1
kind: ReplicationController
metadata:
  name: frontend
spec:
  replicas: 2
  template:
    metadata:
      labels:
        app: search
        tier: frontend
    spec:
      containers:
      - name: node
        image: gcr.io/google_appengine/nodejs
        resources:
          requests:
            cpu: 100m
            memory: 100Mi
        env:
        - name: GET_HOSTS_FROM
          value: dns
        ports:
        - containerPort: 80

由于某种原因，我不断收到状态:CrashLoopBackOff

当我运行 kubectl 日志时，它显示以下内容:

npm ERR! Linux 4.4.21+
npm ERR! argv "/nodejs/bin/node" "/nodejs/bin/npm" "start"
npm ERR! node v6.9.1
npm ERR! npm  v3.10.8

npm ERR! errno -2
npm ERR! syscall open

npm ERR! enoent ENOENT: no such file or directory, open '/app/package.json'
npm ERR! enoent ENOENT: no such file or directory, open '/app/package.json'
npm ERR! enoent This is most likely not a problem with npm itself
npm ERR! enoent and is related to npm not being able to find a file.
npm ERR! enoent 

npm ERR! Please include the following file with any support request:
npm ERR!     /app/npm-debug.log

我四处搜索并找到了运行的建议

npm install -g npm-autoinit

当我只是拉图像时，我不知道该怎么做。我对 Docker 和 Kubernetes 相当陌生，因此我们将不胜感激!

您正在启动一个其中没有任何应用程序的容器。首先，您实际上在某个注册表中拥有一个可用的 docker 化应用程序，确认您知道如何使用纯 docker(即在您的工作站上)启动它，然后才开始将其放入 k8s
