Kafka docker - NoSuchFileException：/opt/kafka.server.keystore.jks

Question

我已经通过docker安装了kafka。 当我运行 docker-compose up 命令时，我遇到以下错误：

 [2022-02-28 08:13:24,185] INFO Awaiting socket connections on localhost:9092. (kafka.network.Acceptor)

Failed to load SSL keystore /opt/kafka.server.keystore.jks of type JKS

下面是我的 docker-compose.yml 文件：

version: '3'

services:
  zookeeper:
    image: wurstmeister/zookeeper
    container_name: zookeeper
    ports:
      - "2181:2181"

  kafka:
    image: wurstmeister/kafka
    depends_on:
      - zookeeper
    container_name: kafka
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_LISTENERS: 'SSL://localhost:9092'
      KAFKA_LISTENERS: 'SSL://localhost:9092'
      KAFKA_AUTO_CREATE_TOPICS_ENABLE: 'true'
      KAFKA_ZOOKEEPER_CONNECT: 'zookeeper:2181'
      KAFKA_SSL_KEYSTORE_LOCATION: '/opt/kafka.server.keystore.jks'
      KAFKA_SSL_KEYSTORE_PASSWORD: 'changeit'
      KAFKA_SSL_KEY_PASSWORD: 'changeit'

      KAFKA_SSL_TRUSTSTORE_PASSWORD: 'changeit'
      KAFKA_SECURITY_INTER_BROKER_PROTOCOL: 'SSL'
    volumes:
      - ./server_certs:/certs

更改变量值以使用 /certs

version: '3'

services:
  zookeeper:
    image: wurstmeister/zookeeper
    container_name: zookeeper
    ports:
      - "2181:2181"

  kafka:
    image: wurstmeister/kafka
    depends_on:
      - zookeeper

    environment:
