Postgresql Postgres不接受Docker中的连接
我正在docker toolbox windows 7 sp1上运行docker项目，该项目没有给出任何错误，但仍然是因为postgres没有在不正常的情况下运行整个项目。 Docker compose文件的代码为：Postgresql Postgres不接受Docker中的连接,postgresql,docker,docker-compose,dockerfile,Postgresql,Docker,Docker Compose,Dockerfile,我正在docker toolbox windows 7 sp1上运行docker项目，该项目没有给出任何错误，但仍然是因为postgres没有在不正常的情况下运行整个项目。 Docker compose文件的代码为： version: '3' services: postgres: image: 'postgres:latest' restart: always ports: - "5432:5432" environment: PO

无论是否有数据卷，都会出现相同的错误，因此项目无法运行。请帮助我假设一旦API启动，它就会尝试连接到Postgres。如果是，这是许多Docker开发人员遇到的典型错误，Postgres DB尚未准备好接受连接，应用程序正在尝试连接到它 您可以通过尝试以下任一方法来解决此问题：
如果这不起作用，我建议您检查容器外部是否安装了Postgres DB，该容器拥有您试图访问的端口。除了Allan Chua的回答，请在docker compose文件中提及对Postgres服务的启动依赖性
