【中文标题】Dockerfile 和 Docker Compose 与 Java Spring Boot、Gradle 和 PostgreSQL [重复]【英文标题】：Dockerfile & Docker Compose with Java Spring Boot, Gradle and PostgreSQL [duplicate] 【发布时间】：2022-01-13 12:52:53 【问题描述】：

您好 *** 用户！我之所以在这里写这个问题，是因为当谈到使用 Docker 的 Spring Boot Java 应用程序时，我发现缺乏资源有点可怕。我的目标是创建一个功能齐全的仓库管理系统，作为 Spring Boot 良好实践的示例，并作为我和其他人在框架的许多概念方面的学习经验。

我正在尝试创建一个 Dockerfile，以便我的应用程序可以作为一个容器中的 Docker 映像与 PostgreSQL 数据库一起运行。

应用程序可以在here on GitHub找到。

应用程序的Dockerfile 是：

FROM gradle:jdk17-alpine
RUN mkdir /home/gradle/buildWorkspace
COPY . /home/gradle/buildWorkspace

WORKDIR /home/gradle/buildWorkspace
RUN ls /home/gradle/buildWorkspace
RUN gradle build --no-daemon
RUN ls /home/gradle/buildWorkspace/app/build/distributions/
RUN tar -xvf /home/gradle/buildWorkspace/app/build/distributions/app.tar
EXPOSE 8080

和docker-compose.yaml

version: '3.9'

services:
  db:
    container_name: "PostgresWarehouseDB"
    image: "postgres:14.0-alpine"
    restart: always
    environment:
      POSTGRES_USER: warehouse_user
      POSTGRES_PASSWORD: warehouse_user_password
      POSTGRES_DB: warehouse_db
    ports:
      - "5432:5432"
    volumes:
      - "./storage/migrations:/docker-entrypoint-initdb.d/"
  app:
    container_name: "SpringWarehouse"
    build:
      dockerfile: Dockerfile
      context: .
    links:
      - "db:database"
    depends_on:
      - db
    ports:
      - 8080:8080
    command: /home/gradle/buildWorkspace/app/build/distributions/app/bin/app

application.properties:


spring.main.banner-mode=off
logging.level.org.springframework=ERROR

spring.jpa.hibernate.ddl-auto=none
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

spring.datasource.initialization-mode=always
spring.datasource.platform=postgres
spring.datasource.url=jdbc:postgresql://localhost:5432/warehouse_db
spring.datasource.username=warehouse_user
spring.datasource.password=warehouse_user_password


# Log JPA queries
# Comment this in production
# spring.jpa.show-sql=true

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect

我正在使用 Java 17、Gradle 7 和最新的依赖项。

我已经设法使用 Gradle 构建应用程序并使用 docker-compose up 和 PostgreSQL 启动它（带有初始迁移）。

我的问题是它似乎无法通过网络访问，所以我的应用程序无法访问数据库，因此无法正常运行。

我得到以下跟踪：

我之前使用过类似的 docker-compose 文件取得了成功，但我不明白我在这里缺少什么。我一定会在这里和我的个人博客中分享我的发现，以帮助未来遇到同样情况的开发人员。

感谢任何帮助。

【问题讨论】：

【参考方案1】：

尝试更新您的application.properties：spring.datasource.url=jdbc:postgresql://db:5432/warehouse_db

【讨论】：

我不清楚。主机名是否仅取决于我们在 docker-compose 或其他属性中设置的服务名称？ ...host name depend simply on service name - 见"...the following happens:"。 注意： 一个例外是如果您使用container_name 覆盖。
