6. AUDIENCE – LEVEL 100
PRODUCT UNIT – CLOUD NATIVE PLATFORM
I’ve heard about containers and Kubernetes. Seems
cool… I’d love a little introduction to it.
I already know Kubernetes. It fits my needs
perfectly, but I do not have enough resources to
manage it. How can OVH help me?
I know containers, and stacks like Mesos/Marahton,
very well. But,Kubernetes?
Just “curious”…
I’m ready to use and deploy containers. Do I need
Kubernetes?

10. THIS IS “CONTAINERISATION”
THIS IS CONTAINERISATION
A container is a standardised unit of
software

11. A “CONTAINER”
THIS IS CONTAINERISATION
Containerised Applications
“Lightweight, standalone, executable
package of software”
“Infrastructure agnostic”
“Everything needed to run an application:
code, runtime, system tools, system
libraries and settings in one package”

12. THIS IS “CONTAINERISATION”
THIS IS CONTAINERISATION
2013: Containerisation becomes easy-to-use and popular, thanks to Docker.

13. THIS IS “CONTAINERISATION”
THIS IS CONTAINERISATION
2014 : Google announces its open-source version of BORG, its own automated cluster
management system.
Kubernetes is born!

14. THIS IS “CONTAINERISATION”
THIS IS CONTAINERISATION
2015 : Containers are the new deployable unit of software, as packaged applications.
This is the rise of micro-service ecosystems.
CI/CD pipelines evolve to build and deploy
immutable applications, like containers.

15. THIS IS “CONTAINERISATION”
THIS IS CONTAINERISATION
https://ovh.to/HegjQA
2016 : CI/CD/CA are container-centric.
Most experts raise the question of how container security is relevant in immutable
architectures.

16. THIS IS “CONTAINERISATION”
2017 : Kubernetes becomes the most popular container management system.
Major SaaS companies migrate to K8S, to reduce their time-to-market and operational costs.
THIS IS CONTAINERISATION

17. HELLO, I’M KUBERNETES
KUBERNETES
Run massive numbers of containers,
based on lessons learned by Google.
Schedule and run all kinds of
containers (short- and long-lived)
Kubernetes can be thought of as a
distributed OS, or process manager.
Container packages your code in a portable way.
Pod gives your code a temporary home inside the cluster.
Deployment keeps your code running , even when it is updated.
Services provides a stable address that can reach many pods.
Kubernetes is a portable, extensible open-source platform for
managing containerised workloads and services, which
facilitates both declarative configuration and automation. It has
a large, rapidly-growing ecosystem. Kubernetes services,
support, and tools are widely available.

18. BUT, I’M NOT…
KUBERNETES
• An hypervisor
• A simple, basic orchestrator
• A better docker-like solution
• A container builder
• An image registry

19. KUBERNETES VS ORCHESTRATOR
Additionally, Kubernetes is not a mere orchestration system. In fact, it eliminates the need for
orchestration. The technical definition of orchestration is execution of a defined workflow: first
do A, then B, then C. In contrast, Kubernetes is comprised of a set of independent,
composable control processes that continuously drive the current state towards the provided
desired state. It shouldn’t matter how you get from A to C. Centralized control is also not
required. This results in a system that is easier to use and more powerful, robust, resilient,
and extensible.

HOW IT WORKS
#Container management
Kubernetes, simplifies container management in complex
ecosytems.
Deploy, Secure, Scale, Monitor

24. HOW IT WORKS
HOW IT WORKS
#Master
Master = n * node
Masters manage the cluster ,and the nodes are used to host the
running applications.

25. HOW IT WORKS
HOW IT WORKS
#NodeA node is a worker machine in Kubernetes, and may be a VM or physical
machine, depending on the cluster. Multiple pods can run on one node.
Node = n * pod
AKA Minion

26. HOW IT WORKS
HOW IT WORKS
#PodA pod is a group of one or more application
containers (such as Docker or rkt), and includes
shared storage (volumes), IP addresses, and
information about how to run them.
Pod = n * container

31. KUBERNETES@OVH
K8S@OVH
As we’re now in BETA:
1. We automatically create a new Public Cloud
project in your manager via Openstack when
ordering your Kubernetes cluster.
2. Spawn your nodes via our Kubernetes
manager, (which will auto-create a new VM in
this Public Cloud project).
3. You have access to all PCI flavours
(standards, not sandbox).
4. We do not bill your master Kubernetes cluster.
5. We only bill your freshly-installed nodes, via
your PCI billing.

32. MANAGED SERVICE: K8S
MANAGED KUBERNETES
It’s simple:
1. We start your Kubernetes cluster(s) in two minutes, as soon as you order it.
2. We watch your cluster(s)’ states, and make sure it is healthy.
3. We operate your cluster(s), but not your application inside your pods.
4. We manage all upgrades and updates.

33. MY FIRST K8S APPLICATION
K8S@OVH
1. Create your cluster
2. Boot a node
3. Deploy your application
4. Explore your application
5. Expose your app publicly
6. Scale your app
7. Update

34. TROUBLESHOOTING
K8S@OVH
Your truly dedicated CLI

35. DEMO TIME!
DEMO
1. Order your own cluster
2. Raise your nodes
3. Install and expose a service
4. Monitor your own lovely cluster

36. RANDOM QUESTIONS
K8S@OVH
How do I manage node resources?
How I choose my deployment location?
How do I scale a service?
How I manager my cluster updates?
How do containers communicate with each other?
Where is my config?
Stateful or stateless?
