Docker in Motion teaches you how to create and manage container-hosted applications in Docker. With over 2 hours of hands-on, practical video lessons, you'll learn the ins and outs of Docker and discover how to apply what you've learned to your own day-to-day development. Starting with an overview of Docker, you'll dive into the commands and techniques you'll need for running and managing containers, creating, modifying, saving and uploading Docker images from scratch, running and building multiple containers with Docker Compose, and more. Inside: An introduction to Docker and how it works Image management Creating Docker images Managing containers Storing and managing data in volumes Linking your Docker containers Running a web server which is connected to a database Configuring containers using docker-compose About the subject Docker creates sandboxed environments, called containers, that isolate your applications from the underlying infrastructure, making them much easier to deploy, migrate, scale, and remove. Each Docker container includes the application and all its dependencies in a single deployable package. Docker has rapidly become a nearly universal part of IT infrastructure in millions of Linux and cloud-based deployments worldwide, including big shops like eBay and Lyft. It's time to join them! Prerequisites No experience with Docker is required. The course assumes basic familiarity with Linux and software development. Peter Fisher is a freelance web and mobile app developer. He's the host of the HowToCodeWell YouTube channel, where he posts weekly tutorials and talks on web development and other subjects.
