django - 尝试在docker-machine cookiecutter-django中运行docker-compose时出现``关系不存在''错误

Question

我已经使用cookiecutter-django完成了Django项目。
如果我只是本地运行:

$ docker-compose -f local.yml build

$ docker-compose -f local.yml up

我的项目在 http://0.0.0.0:8000中正常启动

尽管如此，现在我正在尝试按照本指南进行部署: https://realpython.com/development-and-deployment-of-cookiecutter-django-via-docker/

我已经能够使用 docker-machine create --driver virtualbox dev创建本地docker-machine，将其激活为 eval $(docker-machine env dev)并构建镜像，但是如果我运行 docker-compose -f local.yml up，则会出现以下错误:

如果可能有意义，如果我在启动docker-compose build之前访问docker-machine的IP地址和端口( http://192.168.99.101:2376)，该页面将显示“客户端向HTTPS服务器发送了HTTP请求”。

这是我的“local.yml”:

      # Expose browsersync UI: https://www.browsersync.io/docs/options/#option-ui

运行docker-machine ls的结果:

和我的本地Docker文件:

拜托，我对Django和Docker还是很陌生，所以如果我对自己的解释不正确，请原谅。另外，如果您需要任何其他脚本或信息来正确看待问题，请告诉我!

我不知道您是否已经解决了这个问题，也不知道我是否正确，请尝试一下:
代替:

docker-compose -f local.yml up

尝试:

docker-compose -f production.yml up

部署到生产环境时，应该使用生产文件而非本地文件来构建并启动该站点。
