Put it in a Container

Build

Package application in a container

Ship

Move container to another machine

Run

Execute that container

Any Application

All applications running on Linux

Anywhere

VM on premise, cloud, bare metal

Build

Dockerfile

FROM ubuntu:14.04
MAINTAINER Docker Team <education@docker.com>
RUN apt-get update
RUN apt-get install -y nginx
RUN echo 'Hi, I am your father...erm in your container' \
>/usr/share/nginx/html/index.html
CMD [ "nginx", "-g", "daemon off;" ]
EXPOSE 80

Ship

Docker Hub

Image name <username>/<reponame>
z.B. microsoft/aspnet

docker push
docker pull

https://hub.docker.com/

Run

• Leichtgewichtig
• Schnell

Wie schnell?

Benchmark

$ time docker run ubuntu echo hello world

Docker Footprint

$ sudo docker images

$ sudo docker history <CID>

Any application

• Web apps
• API backends
• Datenbanken (SQL, NoSQL)
• Big data
• Message queues
• ...

Runs on Linux == Runs in Docker

Windows Container?

Nano Server
