Docker Compose启动MongoDB后无数据库和用户问题求助

涉及文件 #

• /mongo/init/init-mongo.js
• .env.development
• docker-compose.yml

问题现象 #

• Mongo实例启动后为空，无用户、数据库及集合
• 执行命令 docker exec -it ord-data-backend-db mongosh 连接容器内mongosh后，运行 show databases 显示为空
• 容器内通过/bin/bash可正常获取docker-compose.yml中定义的环境变量
• 因Mongo实例未完成初始化，mongo-express容器因健康检查失败无法启动

启动命令 #

docker-compose -f docker-compose.dev.yml --env-file .env.development up -d

文件内容 #

docker-compose.yml #
