Introduction to Docker and the DCA Certification [Video]

More Information
  • Improve your odds of passing the Docker Certified Associate exam
  • Understand how to package applications into portable and scalable containers
  • Deploy and scale applications in a cluster using Docker Swarm
  • Master the important aspects of Docker - Images, Volumes, Repos and Networks

Docker is a tool which has greatly simplified the task of packaging your application, along with all its dependencies into lightweight, portable units called containers. These containers are platform independent and can be executed on any host which runs a Linux kernel. Docker is one of the hottest tools in the market right now as a lot of teams have learned how to use it to break up their large, monolithic applications into smaller and more manageable units - often called microservices. This has allowed development teams to work on microservices independently and package it into a container once it is ready. Docker has also eased the pain of DevOps teams who often need to manage the deployment processes and environments - since containers can run independently of each other, they can simply focus on deploying containers rather than worrying about dependencies for each application. Container orchestration tools such as Docker Swarm and Kubernetes have made it very easy to deploy microservices to a cluster and scale them according to demand. For these reasons, Docker is a technology which you need to know if you're an app developer or DevOps engineer.

Style and Approach

This course introduces you to all the main concepts of Docker, and focuses on getting you up and running with the tool in all the lab sections.

  • Images: Templates to define your container
  • Containers: What they are and how Docker helps you create them
  • Storage: Volumes, Bind Mounts and tmpfs to manage data in containers
  • Networks: Regulate connectivity to your containers whether on individual hosts or in a cluster
  • Docker Swarm: The built-in container orchestration tool
  • Docker EE, UCP and DTR: The enterprise offerings of Docker

Loonycorn is Janani Ravi and Vitthal Srinivasan. Between them, they have studied at Stanford, been admitted to IIM Ahmedabad, and have spent years working in tech, in the Bay Area, New York, Singapore and Bangalore. Janani spent 7 years at Google (New York, Singapore); Studied at Stanford and also worked at Flipkart and Microsoft. Vitthal also worked at Google (Singapore) and studied at Stanford; Flipkart, Credit Suisse and INSEAD too. They think they might have hit upon a neat way of teaching complicated tech courses in a funny, practical, engaging way, which is why they are so excited to be here. They hope you will try their offerings, and you'll like them.
