1. Docker – kontejnerizacija na serveru Vedran Vučetić, SPAN

3. Virtualization is the key cloud computing feature.

6. Virtualne masine su velike, GBs
- Docker containers je samo aplikacija i dependencies

7. Docker basics Platform for developers and sysadmins Docker Engine
Docker Hub
images
Apache licence
Usteda na licencama
Lakse raditi scaleup and down
Radi na puno platformi – desktop, fizicki serveri, VMs

8. Architecture

9. Docker images
Osnova containera sudo docker images Image tags ubuntu:14.04 sudo docker pull ubuntu

10. Own process
Own network interface
Share kernel with host

11. Platform basic components
Docker images Docker registries Docker containers
Docker images
A Docker image is a read-only template. For example, an image could contain an Ubuntu operating system with Apache and your web application installed. Images are used to create Docker containers. Docker provides a simple way to build new images or update existing images, or you can download Docker images that other people have already created. Docker images are the build component of Docker.
Docker Registries
Docker registries hold images. These are public or private stores from which you upload or download images. The public Docker registry is called Docker Hub. It provides a huge collection of existing images for your use. These can be images you create yourself or you can use images that others have previously created. Docker registries are the distribution component of Docker.
Docker containers
Docker containers are similar to a directory. A Docker container holds everything that is needed for an application to run. Each container is created from a Docker image. Docker containers can be run, started, stopped, moved, and deleted. Each container is an isolated and secure application platform. Docker containers are the run component of Docker.

16. Stvaranje slike Iz Dockerfile # This is a comment FROM ubuntu:14.04
MAINTAINER Kate Smith
RUN apt-get update && apt-get install -y ruby ruby-dev
RUN gem install sinatra

17. sudo docker build -t ouruser/sinatra:v2 .

18. DEMO: ASP.NET IN DOCKER CONTAINER

19. Tehnical Details run everywhere Regardless of kernel version (2.3.32+)
Regardless of host distro
On premise, on cloud, virtual or not
Container and host architecture must match
If it can run on host, it can run in container

20. Best practices
Portability
Keep images small
One process per container
