在 Kubernetes 部署中找不到二进制文件

Question

我正在尝试在我的测试集群上部署 rocketmq。我从 apache/rocketmq-docker 存储库中提供的脚本开始 github，但它们不起作用。我从我之前引用的 repo 中的那个开始创建了我自己的 yaml 部署，它适用于 mqnamsrv，但不适用于代理。在以下 2 个部署中：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: rocketmq-namesrv
spec:
  replicas: 1
  selector:
    matchLabels:
      app: rocketmq-namesrv
  template:
    metadata:
      labels:
        app: rocketmq-namesrv
    spec:
      containers:
      - name: namesrv
        image: myrepo/rocketmq:4.9.3-alpine
        command: ["sh", "mqnamesrv"]
        imagePullPolicy: IfNotPresent
        resources:
          limits:
            memory: "128Mi"
            cpu: "400m"
        ports:
        - containerPort: 9876
        volumeMounts:
        - name: namesrv-log
          mountPath: /var/log
      volumes:
      - name: namesrv-log
        persistentVolumeClaim:
          claimName: rocketmq-namesrv-pvc

apiVersion: apps/v1
kind: Deployment
metadata:
  name: rocketmq-broker
spec:
  replicas: 1
  selector:
    matchLabels:
      app: rocketmq-broker
  template:
    metadata:
      labels:
        app: rocketmq-broker
    spec:
      containers:
      - name: broker
        image: myrepo/rocketmq:4.9.3-alpine
        command: ["sh", "mqbroker", "-n", "localhost:9876"]
        imagePullPolicy: IfNotPresent
        resources:
          limits:
            memory: "128Mi"
            cpu: "400m"
        ports:
        - containerPort: 10909
        - containerPort: 10911
        volumeMounts:
        - name: broker-log
          mountPath: /var/log
        - name: broker-store
          mountPath: /home/rocketmq
      volumes:
      - name: broker-log
        persistentVolumeClaim:
          claimName: rocketmq-broker-log-pvc
      - name: broker-store
        persistentVolumeClaim:
          claimName: rocketmq-broker-store-pvc

图像 rocketmq:4.9.3-alpine 是按照 apache/rocketmq-docker 存储库中的程序创建的。

部署后 rocketmq-namesrv 工作，但代理的 pod 日志：sh: can't open 'mqbroker': No such file or directory。但是，如果我尝试运行手动 kubectl run -ti rocketmq-broker --image=myrepo/rocketmq:4.9.3-alpine --restart=Never -- sh mqbroker -n localhost:9876 容器，它会工作...

yaml 可能是什么问题？我是不是做错了什么？

我认为是挂载路径的问题。

        - name: broker-store
          mountPath: /home/rocketmq

所以你的二进制文件不会在那里，所以错误
