Download as PPTX, PDF•1 like•783 views
The document discusses the evolution and components of OpenStack, a cloud infrastructure automation stack initiated in 2010, along with its managed development by the OpenStack Foundation. It also introduces Docker and Docker Swarm, highlighting their roles in application deployment and clustering, respectively. The content concludes with a scenario for practical application involving OpenStack and Docker, detailing requirements and resources for implementation.
From OpenStack to Docker swarm
- 1. From OpenStack to Docker swarm Nikolay Milovanov New Bulgarian University [email protected]
- 2. OpenStack facts and figures • Cloud IAAS automation stack • Began 2010 as a project between NASA & RackSpace • First Component is the hypervisor Nebula which now is called Nova • Distributed under Apache license • Developed by a community of around 1800 active committers (increased from 400 to 1500 for less than an year…)
- 3. OpenStack facts and figures • Managed by OpenStack Foundation • Evolves based on a coordinated 6-month release cycle with frequent development milestones • Currently has 14 releases – 15th Ocata is scheduled for Feb 2017 (Apr 2017)

- 6. Docker • Docker is an open-source project that automates the deployment of Linux applications inside software containers • Docker is a wrapper on top of liblxc/libcontainer which are wrappers of a couple of key kernel features – namespaces, originally developed by IBM, wrap a set of system resources and present them to a process to make it look like they are dedicated to that process. – cgroups, originally developed by Google, govern the isolation and usage of system resources, such as CPU and memory, for a group of processes
- 7. Docker Swarm • Native clustering for Docker • Turns a pool of Docker hosts into a single, virtual Docker host • Allows us to do clusters of docker containers
- 8. NBU • First and largest private university in Bulgaria • First to introduce credit system • Has started from two apartments • Now has about 14000 students • Mostly humanitarian university • Clear separation between administration and academic • Technology programs are in – Telecommunications – Informatics • OpenStack lab is hosted by Telecommunications department in Building 2, lab 701a
- 9. TIME FOR FUN
- 10. Scenario • In an OpenStack tenant we will : – create virtual network, subnet and a router – play a bit with the native OpenStack security functionalities such as keys and access-groups – deploy a VM from an cloud image
- 11. That’s what we have to achieve
- 12. Second part • inject user-data and do fun with the VM • deploy automatically docker& docker swarm into an OpenStack VM • If we do all that, we are a real heroes and will play with some containers on top of the swarm cluster
- 13. To do the exercise you will need OpenStack clients • Those will hit straight OpenStack REST APIs • You need to install: – pip install python-novaclient – pip install python-neutronclient – pip install python-glanceclient • Credentials – User: …. – Tenant: …. – Password: …. – GUI (you won’t need it but anyway) – http://java2days.telecom.nbu.bg/dashboard • Slides and workshop scripts – https://goo.gl/sA2xmt

Editor's Notes
- #5: Magnum is an OpenStack API service developed by the OpenStack Containers Team making container orchestration engines such as Docker Swarm, Kubernetes, and Apache Mesos available as first class resources in OpenStack.
