Docker, Kubernetes and WS

Introduction

Docker is the next step beyond virtualization. A Docker image contains everything it needs to run, independent of the Linux / Windows / Mac server / PC on which it lives: a copy of the operating system, a database, code, configuration files, dependencies, and so on. Images can also be packaged and shared with other Docker admins. Here we will introduce the basics of Docker, including its containers, Dockerfiles (or base images), and capabilities for networking, data management, infrastructure optimization, and more.

When deployed with Amazon Elastic Container Service (AWS ECS), you have a solid foundation for monitoring and managing Docker containers, including starting containers and scheduling tasks. This frees up developers to concentrate on your container-based applications—instead of your hosting platform. In this course, the instructor will demonstrate how to use Docker and the powerful features in AWS to build and manage container-based applications. Learn how to create containerized applications, set up AWS ECS, manage container scale and network models, troubleshoot issues, and more.
