Docker encountered a problem deploying Django. .

  docker, question

I use conda to manage the python development environment
Following the tutorial here:https://www.qcloud.com/commun …
All kinds of errors. How did the Django program managed by conda deploy to docker?

Details are as follows:
It is divided into three images, MySQL, NGINX and Web (UWSGI+Django).

All kinds of failure, how all impassability, please help me, by the way, I am using conda management development environment, how to add conda to the mirror I have always been confused.

What version of docker? Try docker service restart first and upgrade docker if you can’t.
