我创建了一个 docker MySql 5.7 映像，然后想更改几个名称。我的 docker-compose.yml 文件最终像这样
version: '3.3'
services:
db:
image: mysql:5.7
restart: always
environment:
MYSQL_DATABASE: 'maps_data'
# So you don't have to use root, but you can if you like
MYSQL_USER: 'myuser'
# You can use whatever password you like
MYSQL_PASSWORD: 'password'
# Password for root access
MYSQL_ROOT_PASSWORD: 'password'
ports:
# <Port exposed> : < MySQL Port running inside container>
- '3406:3306'
expose:
# Opens port 3406 on the container
- '3406'
# Where our data will be persisted
volumes:
- my-db:/var/lib/mysql
# Names our volume
volumes:
my-db:
我想从头开始重建我的图像，并认为“docker-compose up -d --force-recreate”是正确的方法......
localhost:maps davea$ docker-compose down
Stopping maps_db_1 ... done
Removing maps_db_1 ... done
Removing network maps_default

maps_db_1 is up-to-date
Attaching to maps_db_1

但是，当我以 root 用户身份登录时，我在那里看不到我的数据库“maps_data”。不过，在进行更改之前我看到了旧的“db”数据库......

完全从头开始并重建我的 docker MySql 映像的正确方法是什么？
