Fundamentals of Docker, DevSecOps and the Docker Network

Course Description

The course is designed for anyone who wants to learn how to run Docker as application infrastructure within their company. You will learn how to properly "dockerize" applications to make them robust and stable. Little by little, we go through the entire process from installing Docker services, Docker images to creating a dockerized version of the application. And all this respecting the best practices for creating and executing this type of applications. Using practical examples, we will test all the advanced techniques that Docker and its ecosystem offer. Thanks to the extensive practical experience of the speakers, we will also focus on the most common problems and the most frequent errors of Docker users.
