Containers, containers, containers. Containers everywhere! If you are involved in the software
industry at any level, you will have heard about Docker or some similar containerization
technology. Over the past few years, Docker has grown to become a mature piece of software
with a vibrant community that carries radical implications for both developers and DevOps
engineers alike. In short, Docker is a virtualization technology that allows you to create isolated,
minimalistic environments configured with only the absolute necessary dependencies needed
for a specific purpose.
Have you wanted to learn about Docker and what use cases it may have for you? In this
workshop, we will begin with an overview discussion on how containerization technology works
and then explore the Docker CLI by spinning up some containers and building some images.
