Handling Data and Stateful Applications in Docker
Containers run your apps in lightweight units on any cloud or on-prem, using the same runtime everywhere. But how does data work inside containers? This course teaches you all about storage, including containers, images, volumes, and Docker itself.
What you'll learn
Docker containers run your apps in lightweight units on cloud or on-prem, but how does data work inside containers? In this course, Handling Data and Stateful Applications in Docker, you will gain the understanding of how to manage application data in containers which can run anywhere. First, you will learn how Docker builds the container filesystem and how you can persist data outside of the container lifecycle. Next, you will discover Docker volumes, and the ability to use shared storage with volume plugins. Finally, you will explore how Docker itself uses data, and how you can make the best use of your storage by optimizing Docker images. When you are finished with this course, you will have the skills and knowledge of Docker storage that you need to run stateful applications in containers.
