Beginning DevOps with Docker

 
Course Description

The course outlines the power of containerization and the influence this innovation has on development teams and general operations. We also get to understand what DevOps really is, the principles involved and how the process contributes to product health, by implementing a Docker workflow.

Docker is an open source containerization tool, that makes it easier to streamline product delivery and reduce the time it takes to get from a whiteboard sketch of the business to a money-back implementation.

We will start by defining how Docker influences the DevOps process. We will then design and build simple containers, with a clear outline of how applications are involved in the process. Then we will define the key highlights when setting up multiple containers, while setting up a number using docker-compose, Docker's tool for running multi-container applications. We will wind up by having a production-ready application and host it locally (a process that you can replicate in the cloud).
