Docker allows applications to be packaged into standardized units called containers that contain all dependencies and can run on any Linux, Mac or Windows system. Containers provide faster application delivery, easier deployment and scaling, and more efficient use of resources than traditional virtual machines. The document demonstrates how to create a Docker image, build it, and run the containerized application, and provides links to Docker documentation on getting started with installation and use.

- 3. What it is? • Makes possible to package your application into a unit • contains all dependencies needed by the application • contains everything needed to run the application • Docker units (containers) can be compared to virtual machines • Docker image vs virtual machine image

- 5. What it is? • Docker aims to give you • Faster delivery for your application • Deploying and scaling more easily • Achieving higher density and running more workloads • Runs on Linux, Mac and Windows • Docker engine, client, host, daemon, container, image, registry, hub, ….

Editor's Notes
- #7: Docker engine = client + host Image = read-only template which describes a container, e.g. operating system + web server + your web application Container = instance of image Registry = directory/store for images, e.g. docker hub
