我正在嘗試在 docker 中運行我的 Django 應用程式（Nginx、Gunicorn）。
但是對于請求http://167.99.137.32/admin/我有錯誤：（完整日志https://pastebin.com/0f8CqCQM）
onnection to server at "localhost" (127.0.0.1), port 5432 failed: Connection refused
Is the server running on that host and accepting TCP/IP connections?
connection to server at "localhost" (::1), port 5432 failed: Address not available
Is the server running on that host and accepting TCP/IP connections?
我正在嘗試Can't run the server on Django (connection denied) 的答案，但沒有解決我的問題
設定.py

我正在嘗試sudo systemctl start postgresql和sudo systemctl enable postgresql（同樣的錯誤）
uj5u.com熱心網友回復：
postgres 資料庫不再運行在localhost. 在您的情況下（因為您命名了 container db）它是db.
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'lk_potok_2',
'USER': 'postgres',
'PASSWORD': 'post222',
'HOST': 'db',
'PORT': 5432,
},
我真的不明白你為什么要在這里添加這個：
environment:
- DATABASE_URL=postgres://postgres:post222@localhost:5432/lk_potok_2"
因為你不在你的settings.py. 但在這里它也必須db代替localhost.
- 編輯 -
docker可以在這里找到為什么可以識別其他容器的解釋。
