挂载本地文件覆盖ActiveMQ Artemis容器中的默认文件

Question

我使用的图像是

quay.io/artemiscloud/activemq-artemis-broker

。

在我的

docker-compose.yml

中，我使用 root 用户运行容器：

version: "3"
services:
  artemis:
    user: "root"
    image: quay.io/artemiscloud/activemq-artemis-broker
    environment:
      AMQ_USER: admin
      AMQ_PASSWORD: password
      AMQ_RESET_CONFIG: true

    
    volumes:
      # mount local file to container path as a new file works well!
      - ./config/my.json:/home/jboss/broker/etc/my.json

      # mount local file to overwrite a file in container path fails!
      - ./config/login.config:/home/jboss/broker/etc/login.config

    ports:
      - "5672:5672"
      - "61616:61616"
      - "8161:8161"
    networks:
      - backend

networks:
  backend:
    driver: bridge

将本地文件作为新文件挂载到容器路径中

/home/jboss/broker/etc/my.json

效果很好！

但是安装本地文件以覆盖同一路径中的现有文件失败并出现错误：

2024-03-04 22:30:59 Exception in thread "main" java.io.FileNotFoundException: broker/etc/login.config (Permission denied)

我已验证：

我已经验证容器内有

/home/jboss/broker/etc/

目录（默认情况下）并且路径内有

login.config

文件，我尝试覆盖该文件：

[jboss@5905b996368e ~]$ pwd
/home/jboss

[jboss@5905b996368e ~]$ ls
broker

[jboss@5905b996368e ~]$ ls ./broker/etc/
...  login.config
...

那么，如何在主机上挂载本地文件

./config/login.config

来覆盖容器路径中的文件

/home/jboss/broker/etc/login.config

??

Answer 1

仅适用于

loging.config

的简单解决方案是通过设置系统属性

loging.config

将代理指向自定义

ava.security.auth.login.config

路径，即

version: "3"
services:
  artemis:
    user: "root"
    image: quay.io/artemiscloud/activemq-artemis-broker
    environment:
      AMQ_USER: admin
      AMQ_PASSWORD: password
      JAVA_ARGS_APPEND: "-Djava.security.auth.login.config=/opt/amq/login.config"

    
    volumes:
      # mount local file to overwrite a file in container path fails!
      - ./config/login.config:/opt/amq/login.config

    ports:
      - "5672:5672"
      - "61616:61616"
      - "8161:8161"
    networks:
      - backend

networks:
  backend:
    driver: bridge

更通用的解决方案需要覆盖容器命令，即

version: "3"
services:
  artemis:
    user: "root"
    image: quay.io/artemiscloud/activemq-artemis-broker
    environment:
      AMQ_USER: admin
      AMQ_PASSWORD: password

    
    volumes:
      # mount local file to overwrite a file in container path fails!
      - ./config/login.config:/opt/amq/etc/login.config

    command: bash -c "sed 's~  configure~  configure\n  cp --recursive /opt/amq/etc/* /home/jboss/broker/etc~' /opt/amq/bin/launch.sh | source /dev/stdin"

    ports:
      - "5672:5672"
      - "61616:61616"
      - "8161:8161"
    networks:
      - backend

networks:
  backend:
    driver: bridge

或者，当您需要覆盖 /home/jboss/broker 目录中的实例文件时，您可以传递完整的代理实例。
