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.

- 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
