This document summarizes the history and current state of containerization technologies. It discusses early implementations in mainframes and virtualization in the 1990s. It then covers the rise of Docker in 2013 which enabled "write once, run anywhere" for applications. The document also outlines the Docker platform and tools like Docker Hub, Docker Machine, and Docker Compose. It discusses orchestration technologies like Docker Swarm and Kubernetes. Finally, it briefly mentions other container-focused companies and platforms like Tutum, Flocker, and Weave.

5. History of containerization
• 1960’s mainframe
• 1990’s hardware virtualization
• 1990’s OS virt precursors: BSD Jails, Solaris zones
• 2006 Cloud IaaS
• 2009 platform virtualization (PaaS)
• 2013 Docker

20. Docker now
 A platform to build, ship, and run any app, anywhere
 docker engine
 docker hub
 docker-machine
 docker-compose
 docker-swarm
 kitematic

21. Docker for developers
https://registry.hub.docker.com/_/java/

22. docker-compose: running multiple containers
 Run your stack with one command: docker-compose up
 Describe your stack with one file: docker-compose.yml
web:
build: .
command: python app.py
ports:
- "5000:5000"
volumes:
- .:/code
links:
- redis:redis
