POSTGRES_PASSWORD
环境变量才能使用密码创建数据库。node-postgres
需要PGPassword. 都需要是相同的密码。 我正在使用.env.local加载密码和.env用于不需要安全存储并且可以包含在源代码中的常见环境变量。 我的.env文件的关键：
DB_USER=root
# DB_PASSWORD=<PASSWORD>
DB_DBNAME=qr_orders_db
PGUSER=${DB_USER}
PGPASSWORD=${DB_PASSWORD}
PGDATABASE=${DB_DBNAME}
POSTGRES_USER=${DB_USER}
POSTGRES_PASSWORD=${DB_PASSWORD}
POSTGRES_DB=${PGDATABASE}
DB_PASSWORD=root
MyDocker撰写文件：
services:
db:
image: postgres
env_file:
- .env
- .env.local
volumes:
- pgdata:/var/lib/postgresql/data
ports:
- "5432:5432"
volumes:
pgdata:
我运行时输出错误：
：docker compose up为什么它不起作用？如果我在.env之前将.env.local放置，我不会收到错误消息，但是警告持续出现：

我做了一个一些实验，以确认未设置密码，但显然是在设置密码。我不知道为什么我会收到警告消息。

明显地，当.env.local在docker组合文件中加载之前，这不会引发错误。生活之谜，我猜_（ツ）_/。我现在不会将自己的回答标记为被接受的答案，因为我想看看是否有人知道如何摆脱该警告。
