Docker "Global Mentor Week" is your opportunity to #learndocker. to learn how to build, ship, and run modern distributed applications with ease. thanks to the Docker platform. Right now, Docker has developed out a series of self-paced online labs that will be available during the meetup. Docker’s meetup groups worldwide are hosting a series of complimentary events to help newcomers and intermediate users learn Docker. We'll have hands-on labs for both beginners and intermediate users, labs targeting both developers and operations. There is something for everyone. Docker mentor will be on hand at this event to help you prepare. and work through the self-paced materials. Bring your laptop, have fun and learn Docker!

- 38. § Docker Core Components: § Engine : Portable (light/heavy) weight run time, and packaging tool § Registry : Central repos to manage sharing of packaged Docker images, and enabled (build, ship, release, run) workflows ( the default registry Docker HUB) § Containers Eco System § Modular § Check Schedulers § Compliant § OCI § Holistic § End to end workflows
- 41. § Image: The basis of a Docker container § Docker Container: The standard unit in which the application service resides "running image instance" § Docker Engine: Runs on Linux, Creates, ships and runs Docker containers deployable on physical or virtual host locally, in a datacenter or cloud service provider § Docker Machine: Docker Machine is a tool that lets you install Docker Engine on virtual hosts, and manage the hosts with docker- machine commands.You can use Machine to create Docker hosts on your local Mac or Windows box, on your company network, in your data center, or on cloud providers like AWS or Digital Ocean. § Docker Registry: On-premises registry for image storing and collaboration
- 42. Containers • Packages up software binaries and dependencies "minimal" • Isolates software from each other • Container is a standard format • Easily portable across environment • Allows ecosystem to develop around its standard Container
