Docker-Compose + postgres:数据库和用户创建不工作(没有 compose 工作)
Docker-Compose + postgres: database and user creation not working (works without compose)
docs for the postgres Docker image 说明您可以使用环境变量使映像在创建时创建用户和数据库。
我似乎无法使用 docker-compose:
# docker-compose.yml
services:
postgresql:
image: postgres:alpine
environment:
POSTGRES_DB: iotplatform
POSTGRES_USER: iotplatform
POSTGRES_PASSWORD: iotplatform
这就是我 运行:
docker-compose up -d --force-recreate postgresql
docker-compose exec postgresql psql -U iotplatform
# psql: FATAL: role "iotplatform" does not exist
当我 运行 docker-compose exec postgresql env
时,我看到配置的环境变量。
日志没有说明任何特别的内容:

编辑:在没有 docker-compose 的情况下尝试过,它有效。
docker run --name some-postgres -e POSTGRES_PASSWORD=iotplatform -e POSTGRES_DB=iotplatform -e POSTGRES_USER=iotplatform -d postgres:alpine
docker exec -it some-postgres psql -U iotplatform
iotplatform=#
我错过了什么?
在 运行 down
和 up
之后有效。显然 --force-recreate
重置不够困难。
