This document discusses two presentations: 1) "Docker in practice: Looking at its use in Badoo over a year" and 2) "Yellow elephant and his friends (operation of the Hadoop stack in a federal project)". It then provides information on Docker, Ansible, and how Badoo used Docker Swarm to manage container orchestration. Ansible is described as providing cloud provisioning, configuration management, application deployment, and multi-tier orchestration through simple YAML playbooks without requiring agents.

Docker registry
The Registry is a stateless, highly scalable server side
application that stores and lets you distribute Docker
images.
tightly control where your images are being stored
integrate image storage and distribution tightly into your
in-house development workflow
Git-based
Start your registry:
$ docker run -d -p 5000:5000 --name registry registry:2
Pull (or build) some image from the hub:
$ docker pull ubuntu
Tag the image so that it points to your registry:
$ docker tag ubuntu localhost:5000/myfirstimage
Push it:
$ docker push localhost:5000/myfirstimage
Pull it back:
$ docker pull localhost:5000/myfirstimage
Now stop your registry and remove all data:
$ docker stop registry && docker rm -v registry

28. WHAT IS ANSIBLE?
● cloud provisioning
● configuration management
● application deployment
● intra-service orchestration
● Multi-tier deployment
● No agents and no additional custom security infrastructure
● Very simple language (YAML, in the form of Ansible Playbooks)

29. MANAGE YOUR INVENTORY IN SIMPLE TEXT FILES
● By default, used a very simple INI inventory file
● Many services also supported
● Plugins like EC2, Rackspace, OpenStack, and more.
Here's what a plain text inventory file like:
[webservers]
www1.example.com
www2.example.com
[dbservers]
db0.example.com
db1.example.com
