是否可以根据我所在的分支(在Dockerfile中指定)更改数据库？

FROM ubuntu:latest

ENV BRANCH_NAME=mybranch

import os

if os.environ.get('BRANCH_NAME') == 'mybranch':
    # 配置mybranch分支的数据库连接
    database_host = 'mybranch-db-host'
    database_port = 3306
    database_name = 'mybranch-db'
    database_user = 'mybranch-user'
    database_password = 'mybranch-password'
else:
    # 配置其他分支的数据库连接
    database_host = 'other-db-host'
    database_port = 3306
    database_name = 'other-db'
    database_user = 'other-user'
    database_password = 'other-password'
