[英]Newbie needs help understanding Docker Postgres django.db.utils.OperationalError: FATAL: password authentication failed for user "postgres"
我是一个试图遵循本教程的新手。 https://testdriven.io/blog/dockerizing-django-with-postgres-gunicorn-and-nginx/#postgres
我成功构建了 docker 容器，但收到此错误 django.db.utils.OperationalError: FATAL: password authentication failed for user "postgres"。
我的问题是当 python 和 postgres 容器 env 显示正确的用户和密码时，为什么身份验证失败？ 我该如何解决这个问题？
我还尝试四处寻找 pg_hba.conf （因为以前的答案建议对其进行编辑）但 /etc/postgresql 对我来说似乎不存在。
这是来自我的 python 容器。

>>> os.environ.get("SQL_ENGINE")
'django.db.backends.postgresql'
>>> os.environ.get("SQL_DATABASE")

>>> os.environ.get("SQL_USER")
'postgres'
>>> os.environ.get("SQL_PASSWORD")
'password123'
>>> os.environ.get("SQL_HOST")
'db'
>>> os.environ.get("SQL_PORT")
'5432'
这是来自我的 postgres 容器。

这与 docker 重启策略直接相关。 根据您的配置， restart: always ，如果容器停止，则始终重新启动。 这可能会扭曲容器的正确顺序。 我建议删除此特定行（它适用于我的情况）。
有时在 docker 容器中设置 postgres 时，您可能会错误地设置密码，并且这些错误设置将持续存在。 当我收到此错误时，我总是尝试的第一件事是销毁该卷并重新创建它。
使用-v来执行此操作，如下所示：
docker-compose down -v
然后再次提出来。
我仍然不确定为什么会发生这种情况，但是当我使用 ubuntu 21.04 在我的新计算机上运行它时没有问题。 我无法访问安装了 windows 的以前的计算机，因此我将其标记为已关闭。 感谢所有试图提供帮助的人：）
