What is Docker?

Docker in 2013 A lightweight runtime and robust tooling to build and run virtual containers on Linux to create the operating environment for your distributed applications.

Docker API host containers

Docker Basics Docker Image The basis of a Docker container Docker Container The standard unit in which the application service resides Docker Engine Creates, ships and runs Docker containers deployable on physical or virtual host locally, in a datacenter or cloud service provider Docker Registry On-premises registry for image storing and collaboration

Applications are changing Loosely Coupled Services Many Small Servers ~2000 Today Monolithic Big Servers Slow changing Rapidly updated

Solution: Docker containers • Packages up software binaries and dependencies • Isolates software from each other • Container is a standard format • Easily portable across environment • Allows ecosystem to develop around its standard Container

so, why containers? STANDARDIZATION … facilitate commoditization of formerly custom processes and help maximize compatibility, interoperability, safety, repeatability, and quality. - wikipedia

Why Developers Care? • Build once…(finally) run anywhere • A clean, safe, hygienic and portable runtime environment for your app. • No worries about missing dependencies, packages and other pain points during subsequent deployments. • Run each app in its own isolated container, so you can run various versions of libraries and other dependencies for each app without worrying • Automate testing, integration, packaging…anything you can script • Reduce/eliminate concerns about compatibility on different platforms, either your own or your customers. • Cheap, zero-penalty containers to deploy services? A VM without the overhead of a VM? Instant replay and reset of image snapshots? That’s the power of Docker

Why Ops Care? •Configure once…run anything • Make the entire lifecycle more efficient, consistent, and repeatable • Increase the quality of code produced by developers. • Eliminate inconsistencies between development, test, production, and customer environments • Support segregation of duties • Significantly improves the speed and reliability of continuous deployment and continuous integration systems • Because the containers are so lightweight, address significant performance, costs, deployment, and portability issues normally associated with VMs

Containers vs. VMs

Docker in 2016 A Containers as a Service (CaaS) platform which enables IT Ops managed and secure application environment (infrastructure and content) for developer self service to build and deploy applications.

Birthday App Training

www.docker.com/docker-toolbox

What's in the toolbox: ● Docker Client ● Docker Machine ● Docker Compose ● Docker Kitematic ● VirtualBox

Birthday App Training Participants in the training will go through the steps involved in running and developing a simple voting app from a fresh computer using Docker Toolbox. This simple app will include: ● A Python webapp which lets you vote between several options ● A Redis queue which collects new votes ● A Java worker which consumes votes and stores them in… ● …A Postgres database backed by a Docker volume ● A Node.js webapp which shows the results of the voting in real timedocker-toolbox All training materials available at: https://github.com/docker/docker-birthday-3 There is a self-paced beginners’ tutorial for attendees to learn Docker basics as they build and deploy this app locally and push their Docker images to Docker Hub. Experienced Docker users will serve as mentors to help beginners successfully complete the training.

Let’s get started with this Docker Training! github.com/docker/docker-birthday-3/ click on tutorial.md
