Assessment Questions

RESEARCH AND THOROUGHLY Answer these questions. This shouldn't take just a trivial amount of time. You should spend some signifigant time on this.

What is the main purpose of using a "container orchestration platform" such as Kubernetes or Docker Swarm?

Now that you have spent the week learning about some deployment options, the main goal here is to get your personal projects up on the world wide web for all to see!
Once you get your project hosted, clean it up so people can interact with it at least a little bit. And if you feel so inclined, solicit feedback in the show-it-off channel in slack.
Another task you can do once you are done hosting your project is craft some really great documentation.
Lastly, continue pushing forward on your personal projects! Build features, figure out problems etc.
