在docker上启动postgres之后,任何尝试连接到数据库的尝试都会导致以下结果;

sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) could not connect to server: Connection refused (0x0000274D/10061)
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 5432?
could not connect to server: Connection refused (0x0000274D/10061)
        Is the server running on host "localhost" (127.0.0.1) and accepting
        TCP/IP connections on port 5432?

此错误的背景位于:http://sqlalche.me/e/e3q8

我已经研究过类似的问题,并且我的端口也是如此分配的;

ports:
 - 5432:5432

详细信息

  • 使用venv的Flask服务器
  • Windows 10

其他详细信息

Dockerfile(用于postgres)

FROM postgres:9.6-alpine

COPY init-db /docker-entrypoint-initdb.d/

应用程序文件(FLASK_APP)这是破解它的命令

@application.cli.command(with_appcontext=True)
def create_db():
    db.engine.execute("CREATE EXTENSION IF NOT EXISTS fuzzystrmatch;")

    db.drop_all()
    db.create_all()
