Question

我有一个Spring项目并使用application.yml文件来运行配置它。在配置文件中使用占位符并将其作为构建的docker镜像运行时，它不会评估占位符，而在运行没有docker的jar时这可以正常工作。这可能有什么问题？

org.postgresql.util.PSQLException: FATAL: password authentication failed for user "${POSTGRES_DB_USER}"

application.yml

server:
  compression:
    enabled: true
    mime-types: application/json,application/xml,text/html,text/xml,text/plain
  context-path: /
  port: 8085

logging:
  config: config/log4j2-spring.xml

spring:
  datasource:
    url: jdbc:h2:./data/cdr
    username: sa
    password:
  jpa:
    hibernate:
      ddl-auto: create-drop

security:
  user:
    password: secretpassword

spring:
  profiles: docker
  datasource:
    url: jdbc:postgresql://postgres/databasename
    username: ${POSTGRES_DB_USER}
    password: ${POSTGRES_DB_PASS}

我想你想要这个：

version: '2'
services:
  application:
    image: domain.com:3000/application:0-SNAPSHOT
    volumes:
      - application-logs:/application/logs
    ports:
      - 8085:8085
    environment:
      POSTGRES_DB_USER: user
      POSTGRES_DB_PASS: secretpassword
  postgres:
    image: sameersbn/postgresql:9.5-2
    volumes:
      - postgres-data:/var/lib/postgresql
    environment:
      DB_NAME: databasename
      DB_USER: user
      DB_PASS: secretpassword

volumes:
  postgres-data: {}
  application-logs: {}

Spring上的docker，环境变量未使用配置占位符进行评估
