带Spring Boot应用程序的Docker Secret在Docker Swarm模式/运行/机密下不工作

我尝试为MySQL容器和SpringBoot应用程序设置数据库密码的环境变量,这通常在Docker机密中声明。

echo "db_secured_password" | docker secret create secret -

以下是配置文件:

Spring引导应用程序的->application.yml

db:
  name: my-db
  host: localhost
  port: 3306
  username: root
  password: /run/secrets/db-root-password
spring:
  application:
    name: core-backend
  datasource:
    url: jdbc:mysql://${db.host}:${db.port}/${db.name}
    username: ${db.username}
    password: ${db.password}

用于docker swarm模式下的docker堆栈->docker-compose.yml

version: '3.1'

services: 

  mysql-db:
    container_name: mysql-db
    image: mysql:8.0.12
    deploy:
      restart_policy:
        condition: on-failure
    volumes:
      - ./data/mysql:/var/lib/mysql
      - ./conf/mysql/my.cnf:/etc/mysql/conf.d/my.cnf
    environment:
      - MYSQL_ROOT_PASSWORD=/run/secrets/db-root-password
      - MYSQL_DATABASE=my_db
    ports: 
      - "3306:3306"
    secrets: 
      - db-root-password

  spring-boot-app:
    container_name: spring-boot-app
    image: spring-boot-app:local
    environment:
      - DB_PASSWORD=/run/secrets/db-root-password
# Also tried adding with the file as property name
#     - DB_PASSWORD_FILE=/run/secrets/db-root-password
    ports:
      - "8080:8080"
    environment:
      HOST_NAME: localhost
    secrets: 
      - db-root-password
    depends_on:
      - mysql-db

secrets:
  db-root-password:
    external: true

我使用以下命令运行Docker堆栈:

docker stack deploy --with-auth-registry -c docker-compose.yml test-stack 

我无法得到 db-root-password 属性完全正确 在春季启动应用程序。当我检查 数据库根密码 我 获取值为 /run/secrets/db-root-password .

有什么东西不见了吗? 如果我想以不同的方式重写环境变量的值?
