Start Lab

In this Lab, we’ll start with a very basic app, create a container, and improve it iteratively.

During this Lab, you will complete the following tasks:

  • Inspect an app and apply Twelve-Factor principles
  • Building a simple container
  • Switch to a distroless image
  • Run as a non-root user
  • Sign and validate signatures

While doing this, we will take a closer look at code style and performance of the container build process.
