Hi everyone,

I’m fairly new to docker so my question may sound stupid. I am trying to deploy a django application using docker. There are commands like `migrate` or `collectstatic` that needed to be executed by my app user (it’s a new user I create on my Dockerfile). So I have a file called `container_start.sh` that I call using `CMD`. Now when all the commands are executed, I need to call `supervisord -n` as root. The issue is using sudo should be avoided according to [https://docs.docker.com/engine/userguide/eng-image/dockerfile\_best-practices/](https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/). So how can I actually switch between my web user and root during CMD?

Thanks
