Summary
In this chapter, we covered the fundamentals of containers and how to build and run them using Docker. Containers provide a lightweight and portable way to package applications and their dependencies so they can run reliably across environments.
You learned about key concepts such as images, containers, Dockerfiles, and registries. We installed Docker and ran simple containers such as NGINX and Julia to get hands-on experience. You built your own containers for a batch processing job and API service, defining Dockerfiles to package dependencies.
These skills allow you to develop applications and containerize them for smooth deployment anywhere. Containers are super useful as they ensure your software runs exactly as intended every time.
In the next chapter, we will look at orchestrating containers using Kubernetes to easily scale, monitor, and manage containerized applications. We will take a look at the most important Kubernetes concepts and components and learn how...
