Because we are not only shipping code and we are no longer Microsoft developers but .NET developers, it's time to open your mind and to see what is offering the OSS world. Docker is an amazing tool. Docker did popularize container and brought a way to manage it. Ok, seems to be cool, but why do developers care? - Static application environment: we know exactly what we are running - Repeatable, runnable artifact: we can deploy everywhere, anytime - Loosely coupled: we can manage, isolate, and compose at environment level easily Please have a look to this Betclic presentation and remember that .NET CLR are coming in GNU/linux world!

1. Docker
Build, Ship and Run any app, anywhere

2. What is Docker?
Docker is an open platform for developers and sysadmins to build, ship,
and run distributed applications. Consisting of Docker Engine, a portable,
lightweight runtime and packaging tool, and Docker Hub, a cloud service
for sharing applications and automating workflows […]
Solomon Hykes, Docker’s Founder & CTO

3. What is container?
Container are to virtual machines as threads are to processes. Or
you can think of them as chroot on steroids.

• More than a sandbox, less than a VM
• Deployable and runnable artifact
• Lightweight Linux environment

5. Why using container?
• We are not only shipping code but conf, environment and
code
• Containers are lightweight, fast, isolated and reproducible
environments
• Docker provides a simple way to write, version, build,
deploy and run environments

6. #> Let’s give a try

7. #> Run container
#> docker images
#> docker run -t -i ubuntu /bin/bash
#> uname -r
#> docker images
#> docker run -t -i centos /bin/bash
#> uname -r
#> docker images

8. #> Run container
#> docker pull nginx
#> docker run --name nginx_inst1 -d nginx
#> docker ps
#> docker stop nginx_inst1
#> docker ps
#> docker ps -a
#> docker start nginx_inst1
#> docker ps

9. #> Container & Host - Network
#> docker run --name nginx_network -d -p 8080:80 nginx
#> curl http://127.0.0.1:8080
#> docker inspect nginx_network | grep IPAddress
#> iptables -t nat -L

10. #> Container & Host - Filesystem
#> mkdir /docker_nginx_fs
#> echo "Hello World!" > /docker_nginx_fs/index2.html
#> docker run --name nginx_fs -d -p 8081:80 -v
/docker_nginx_fs:/usr/share/nginx/html nginx
#> curl http://127.0.0.1:8081/index2.html

11. #> Dockerfile
FROM ubuntu:14.04
RUN
sed -i 's/# (.*multiverse$)/1/g' /etc/apt/sources.list &&
apt-get update && apt-get install -y mono-complete
ADD ./publish/ /publish
EXPOSE 8123
CMD ["mono", "/publish/HelloWorld.exe"]

12. #> Build container
#> git clone https://github.com/MiKaDoO/nancyfx-ubuntu-
docker.git
#> docker build -t mickael/hello-nancy
#> sudo docker run -p 8082:8123 -d mickael/hello-nancy
#> curl http://127.0.0.1:8082
