我想在k8s集群中部署一个Kafka。我有一个zookeeper，部署时没有任何问题，但部署kafka时，它没有运行，并卡在crashloopbackoff中。我检查了它的日志，下面是它的日志：

===> User uid=1000(appuser) gid=1000(appuser) groups=1000(appuser)
===> Configuring ...
===> Running preflight checks ...
===> Check if /var/lib/kafka/data is writable ...
Command [/usr/local/bin/dub path /var/lib/kafka/data writable] FAILED !

下面是我的部署文件：

kind: Deployment
apiVersion: apps/v1
metadata:
  name: kafka-broker0
spec:
  replicas: 2
  selector:
    matchLabels:
        app: kafka
        id: "0"
  template:
    metadata:
      labels:
        app: kafka
        id: "0"
    spec:
      containers:
      - name: kafka
        image: confluentinc/cp-kafka:6.2.2
        ports:
        - containerPort: 9092
        env:
        - name: KAFKA_ADVERTISED_LISTENERS
          value: PLAINTEXT://127.0.0.1:9092
        - name: KAFKA_ZOOKEEPER_CONNECT
          value: zoo1:2181
        - name: KAFKA_BROKER_ID
          value: "0"
        - name: KAFKA_CREATE_TOPICS
          value: input:1:1, output:1:1
        volumeMounts:
        - mountPath: /var/lib/kafka/data
          name: kafka-data
      volumes:
      - name: kafka-data
        persistentVolumeClaim:
          claimName: kafka-data

我发现了这个link，但是在所有的解决方案中，都是关于用docker部署的，并且没有任何针对kubernetes的解决方案。另外，我试图添加user: root或user: "0:0"，但是我找不到如何添加它。
