    Build and push

    Make a docker image that can be used to run your flask app. Please create the following files:

    • Dockerfile this should do normal dockerfile things :)
    • build.sh This should be a shell script that you can use to quickly build your image and give it the right name. Here is an example build script from the Tilde code base:
    #!/bin/sh

docker build -t umuzi-org/tilde-backend .
    • push.sh executing this script should push your image to dockerhub

    Docker-compose

    Create a docker-compose.yaml file. This should be used to launch your app and database.

    • Make use of volumes to make sure you can store your logs on your computer
    • Make use of port mapping so that your application is accessible
    • Make use of environmental variables to set the logging level to log the debug messages.
