在docker-compose.yml中,我更改了

到
希望停止使用预构建的docker映像,并在开发机器上使用代码。但我对视图所做的任何更改(例如,仅将视图上的某些标题文本从“Admin Brand”更改为“My New Header”)都会被忽略。我试过了
docker-compose down
docker-compose up
同样,我尝试了docker compose构建或docker compose重启
所以Docker显然是在缓存源代码,而不是使用我编辑的源代码的“实时”版本
我经常使用Vagrant,但我对Docker很陌生,因此如果您能帮助修改Docker项目以允许本地开发更改,我将不胜感激。如果您使用:
volumes:
rails-assets:
driver: local
您告诉docker创建一个卷并将数据放入其中
但如果要与容器实时同步共享本地代码,则需要执行以下操作:
helpy:
image: helpy/helpy
restart: always
networks:
- front
- back
volumes:
- ./local/path/to/your/code:/helpy/public
现在,当您更改本地代码时,容器内的代码将同时更改。您的源代码是否正确?如果没有,您应该查看它……您能显示
Dockerfile
?

docker-compose up
