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?

VM TO CONTAINERS
THIS IS “CONTAINERISATION” THIS IS CONTAINERISATION A container is a standardised unit of software © Docker
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”
THIS IS “CONTAINERISATION” THIS IS CONTAINERISATION 2013: Containerisation becomes easy-to-use and popular, thanks to Docker.
THIS IS “CONTAINERISATION” THIS IS CONTAINERISATION 2014 : Google announces its open-source version of BORG, its own automated cluster management system. Kubernetes is born!
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.
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.
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
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.
BUT, I’M NOT… KUBERNETES • An hypervisor • A simple, basic orchestrator • A better docker-like solution • A container builder • An image registry
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 HOW IT WORKS #Container management Kubernetes, simplifies container management in complex ecosytems. Deploy, Secure, Scale, Monitor
HOW IT WORKS HOW IT WORKS #Master Master = n * node Masters manage the cluster ,and the nodes are used to host the running applications.
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
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

KUBERNETES@OVH K8S@OVH PCI (Public Cloud )
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.
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.
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
TROUBLESHOOTING K8S@OVH Your truly dedicated CLI
DEMO TIME! DEMO 1. Order your own cluster 2. Raise your nodes 3. Install and expose a service 4. Monitor your own lovely cluster
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?
