Docker Fundamentals

Docker containers are the future of highly scalable software systems and make it easy to create, run, and deploy apps. The workshop starts with an overview of Docker containers, enabling you to understand howthey work. You’ll run third-party Docker images and also create your own images using Dockerfiles and multi-stage Dockerfiles. Next, you’ll create environments for Docker images, and expedite your deployment process with continuous integration. Moving ahead, you’ll tap into interesting topics and learn how to implement production-ready environments using Docker Swarm. To further secure Docker images and ensure that production environments are running at maximum capacity, you’ll apply best practices. Later, you’ll gain the skills to successfully move Docker containers from development to testing, and then into production. While doing so, you’ll learn how to troubleshoot issues, clear up resource bottlenecks and optimize the performance of services.
