Having now learned how containers in general work, and how to create the required infrastructure around them (for example, registries), let's have a look how to create a customer container from a custom app.

A good tutorial on creating a custom container from your app can be found at https://docs.microsoft.com/en-us/azure/container-instances/container-instances-tutorial-prepare-app.
