Docker image runs as root

[blueprismo]

Is your feature request related to a problem? Please describe.
Not a problem, but a vulnerability! :) It's not a best practice to run docker images as the root user

Describe the solution you'd like
Run the app as a non-root user

Describe alternatives you've considered
Same as above

Additional context
It's a few lines of code in the Dockerfile, I volunteer to do it if you want :)
