This document provides an overview of Docker, an open platform for building and distributing applications. It describes Docker as allowing developers to package applications and dependencies into standardized units. It explains how Docker differs from virtual machines by using containers. Some key benefits of Docker include accelerating developer onboarding, eliminating environment inconsistencies, and easily distributing and sharing applications. The document then briefly outlines several Docker products like Engine, Compose, Machine, and Registry before providing examples of common Docker commands and a Dockerfile usage.

2. What is Docker?
Docker allows you to package an application
with all of its dependencies into a
standardized unit for software development.

3. How is this different from virtual machines?
Virtual machines Containers

4. How does this help you build better software?
● Accelerate Developer Onboarding
● Empower Developer Creativity
● Eliminate Environment Inconsistencies
● Distribute and share content
● Simply share your application with others

5. Ship More Software Faster
● Ship 7X More
● Quickly Scale
● Easily Remediate Issues

6. Docker products
● Docker Engine
● Docker Compose
● Docker Machine
● Docker Swarm
● Docker Registry
● and much more …

7. Docker Engine
$ docker
$ docker run hello-world
$ docker run debian:jessie bash
$ docker run -it debian:jessie bash
$ docker run -it -v $(pwd):/data debian:jessie bash
$ docker run -p 80:80 -v $(pwd):/usr/share/nginx/html nginx

8. Docker Engine - Dockerfile
Dockerfile is a text document. It is a blueprint for build
your custom image.
FROM debian:jessie
MAINTAINER adam@rekurzia.sk
RUN apt-get update
RUN apt-get install htop

9. Docker Compose
Docker Compose allows you to define your
multi-container application with all of its
dependencies in a single file …
docker-compose.y(a)ml
$ docker-compose

10. Docker Machine
Automate Docker provisioning
Supported Drivers: Amazon Web Services, Microsoft Azure,
Digital Ocean, Google Compute Engine, Generic, Microsoft
Hyper-V, OpenStack, Rackspace, Oracle VirtualBox, VMware
$ docker-machine create --driver=parallels foo
