Agenda

  • Microservices
  • Herausforderungen
  • Wie hilft Docker?
  • ASP.NET 5 mit Docker deployen

 

Microservices

In computing, microservices is a software architecture style, in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs.

 

These services are small, highly decoupled and focus on doing a small task.

http://en.wikipedia.org/wiki/Microservices

Beispiel: E-Commerce

  • Web Front-End
  • Product Data Management (PDM)
  • Lager
  • Einkauf
  • Versand
  • Payment-Dienstleister
  • Rechnungs- und Mahnwesen
  • Identity

Vorteile

  • Verschiedene Plattformen für verschiedene Services
  • Austausch / Refactoring von Services einfacher
  • Entkopplung beim Deployment
  • "Two-Pizza"-Regel umsetzbar
  • (Code) Ownership einfacher

Herausforderung: 

Komplexität

Komplexität

  • Significant Operations Overhead
  • Substantial DevOps Skills Required
  • Implicit Interfaces
  • Duplication Of Effort
  • Distributed System Complexity
  • Asynchronicity Is Difficult!
  • Testability Challenges

Anforderungen an Deployment

  • Schnell
  • Zuverlässig
  • Reproduzierbar

Deployment automatisieren!

Wie hilft Docker?

Build, ship and run any application anywhere

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 sudo 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

Getting started

http://www.docker.com/tryit/

http://boot2docker.io/

curl -sSL https://get.docker.com/ | sh

Try

On OS X / Windows

On Linux

Install

ASP.NET 5 in Docker

microsoft/aspnet

Demo

ASP.NET 5 in Docker

Next Steps

  • Docker Machine
  • Docker Compose
  • Docker Swarm

Docker Machine

$ docker-machine create --driver virtualbox dev

Docker Compose

web:
  build: .
  links:
   - db
  ports:
   - "8000:8000"
db:
  image: postgres

Fragen?

Danke!
