Docker and Kubernetes Core Concepts

Containers have revolutionized the process of developing and deploying applications. They offer many benefits including consistency between environments, predictable deployments, application scaling, management of microservices, and more. While this all sounds great in theory, how do you integrate containers into your existing business processes and reap the benefits they offer? How do you manage containers in production, scale and monitor them, and fix issues that come up?

The Docker and Kubernetes course provides a hands-on look at containers and the role they can play in your development and deployment environments and workflows. You’ll learn about the many benefits containers provide, how you can use containers in your environment to work with web servers, databases (and more), key Docker tools and commands that you need to learn to use Docker effectively, how to work with images and containers, as well as how to get a fully functional container environment up and running.

After learning the ins-and-outs of containers, the course provides information on how Kubernetes can be used to orchestrate containers. This includes providing a look at the different components that Kubernetes provides (pods, deployments/replicasets, services and more), how to deploy containers, troubleshoot pods, and working with Kubernetes in the cloud.
