Description

Docker and other containerization tools have taken the devops world by storm. Knowing at least the basics of docker has become mandatory for any role of software development you are in. However, for devops engineers/ site reliability engineers, a more detailed understanding of docker and other containerization technologies are desired. It does not entirely cut it to know just how to run basic commands on docker and make it work.

This course focuses on how docker works under the hood. It will guide you through the internal workings of the docker daemon and it's interaction with the linux operating system step by step and explain how docker uses various linux kernel functionalities to make and run containers.

Besides a look at how docker operates under the hood, we will also take a look at basic docker commands, structure of build files etc-. We will also take a look at how to use docker compose to stand up a basic development environment for micro services. We will also look at building minimal container images to save on network throughput, disk size and also faster deployments. We will also be looking at what container orchestrators are and will have a hands-on session about the amazon ECS container orchestrator.

A bit of networking and linux knowledge is assumed for this course. Linux knowledge will help you all throughout the course and networking knowledge will come in handy when we cover the concepts pertaining to networking namespaces.
