docs for the postgres Docker image解释说,您可以使用环境变量使映像创建用户并在创建数据库时创建数据库。
我似乎无法使用docker-compose来完成这项工作:
# docker-compose.yml
services:
postgresql:
image: postgres:alpine
environment:
POSTGRES_DB: iotplatform
POSTGRES_USER: iotplatform
POSTGRES_PASSWORD: iotplatform
这就是我的运行方式:
docker-compose up -d --force-recreate postgresql
docker-compose exec postgresql psql -U iotplatform
# psql: FATAL: role "iotplatform" does not exist
运行docker-compose exec postgresql env
时,我看到环境变量已配置。
日志中没有特别说明:

我想念什么?
答案 0 :(得分:0)
运行down
和up
后,它可以工作。显然,--force-recreate
重置起来并不足够。
