以上 docker compose up log IPv4 和 IPv6 监听端口 5432。但是，为什么 postgresqldb 连接到端口 5433。

我已将 application.properties 定义为：

spring.datasource.url=jdbc:postgresql://postgresqldb:5432/employeedb
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.jpa.show-sql=true
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=create

和 docker-compose.yml 一样

version: '3.1'
services:
  app:
    container_name: springboot-postgresql
    image: springboot-postgresql
    build: ./
    ports:
      - "8080:8080"
    depends_on:
      - postgresqldb
  postgresqldb:
    image: postgres
    ports:
      - "5432:5432"
    environment:
      - POSTGRES_PASSWORD=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_DB=employeedb

即使我检查了与 5432 端口连接的数据库。

但是，我在尝试时仍然遇到错误

码头工人组成

如果可以解决我的错误，请说明我如何将我的 postgresdb 连接到 5432 端口？

我检查了 postgresql.conf，它显示 5432 端口。

【问题讨论】：

【参考方案1】：

从日志来看，数据库已启动并准备就绪。

我认为问题在于.jar的构建过程

能否尝试在项目目录下使用以下命令构建jar：

./mvnw clean package -DskipTests

然后再次尝试docker-compose up。

【讨论】：

我试过这个但没有用，我认为数据库没有准备好，因为错误日志显示：连接到 postgresqldb:5433 被拒绝。检查主机名和端口是否正确，以及 postmaster 是否接受 TCP/IP 连接。数据库已启动并在 postgres 映像日志中准备就绪：

[36mpostgresqldb_1  |[0m 2021-05-26T18:27:35.188808600Z 2021-05-26 18:27:35.188 UTC [1] LOG:  database system is ready to accept connections

。我尝试了回购，我的电脑上没有错误。您是否在 docker/机器上运行了其他 postgres？你用过windows吗？在运行之前，我已经删除了在 docker 中运行的其他容器/图像。即使那样，它也给出了同样的错误。你试过docker rmi springboot-postgresql 让我们重新从头开始构建镜像吗？如果您在删除图像时遇到错误，请尝试docker rmi -f springboot-postgresql。我认为重新创建图像可以解决您的问题。

以上是关于运行 docker compose up 时 Postgres db 未连接到 docker的主要内容，如果未能解决你的问题，请参考以下文章

如何在系统启动时运行 docker-compose up -d？

使用 docker-compose up 运行时如何优雅地停止 Dockerized Python ROS2 节点？

对于nginx容器，docker-compose up失败

使用`docker-compose run`时无法调试，但`docker-compose up`有效

无法弄清楚为啥 docker compose up 没有运行我的 React JS 应用程序
