The document provides an overview of Docker and Kubernetes. It explains that Docker is a tool that allows applications to be run in isolated containers, while Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. The document outlines basic Kubernetes concepts like pods, replication controllers, services, deployments and rollouts that allow scheduling and maintaining application containers across a cluster.
You think Docker is awesome - well than we have something for you: Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications.
In our first MeetUp we will give you a high-level overview on this tool and give you the chance to chat with other intersted people.

XP Days Ukraine 2015 Talk http://xpdays.com.ua/programs/scaling-docker-with-kubernetes/
Kubernetes is an open source project to manage a cluster of Linux containers as a single system, managing and running Docker containers across multiple Docker hosts, offering co-location of containers, service discovery and replication control. It was started by Google and now it is supported by Microsoft, RedHat, IBM and Docker Inc amongst others.
Once you are using Docker containers the next question is how to scale and start containers across multiple Docker hosts, balancing the containers across them. Kubernetes also adds a higher level API to define how containers are logically grouped, allowing to define pools of containers, load balancing and affinity.
Managing Docker Containers In A Cluster - Introducing KubernetesMarc Sluiter
Containerising your applications with Docker gets more and more attraction. While managing your Docker containers on your developer machine or on a single server is not a big hassle, it can get uncomfortable very quickly when you want to deploy your containers in a cluster, no matter if in the cloud or on premises. How do you provide high availability, scaling and monitoring? Fortunately there is a rapidly growing ecosystem around docker, and there are tools available which support you with this. In this session I want to introduce you to Kubernetes, the Docker orchestration tool started and open sourced by Google. Based on the experience with their data centers, Google uses some interesting declarative concepts like pods, replication controllers and services in Kubernetes, which I will explain to you. While Kubernetes still is a quite young project, it reached its first stable version this summer, thanks to many contributions by Red Hat, Microsoft, IBM and many more.

During this meetup we are going to discuss the following topics and share some best practices
• What's new with Kubernetes 1.3
• Generate Cluster Configuration using CloudFormation
• Deploy Kubernetes Clusters on AWS
• Scaling the Cluster
• Integrating Ingress with Elastic Load Balancer
• Using Internal ELB's as Kubernetes' Service
• Using EBS for persistent volumes

Fission: Serverless Functions for KubernetesSoam Vasani
"Serverless" functions allow users to easily create services from source code without dealing with the packaging, deployment, scaling, etc.
Fission is a serverless function framework built on Kubernetes. Users write functions and map them to HTTP routes. They don't have to deal with container images, registries or even learn Kubernetes in much detail.
Functions can be associated with HTTP routes, events, or timers. Functions consume CPU and memory resources only when running; they are started on-demand and killed when idle. Fission makes on-demand function loading very fast, by keeping an idle pool of containers running, in effect creating a distributed "threadpool".
Fission is useful for:
* Creating web app backends or REST APIs
* Implementing webhooks
* Writing event handlers
We'll demo the creation of a simple web app using Fission functions in Python.
We'll also show how tying together Kubernetes Watches and Fission functions make it very easy to write custom behavior triggered by changes to arbitrary resources on Kubernetes.
All the troubles you get into when setting up a production ready Kubernetes c...Jimmy Lu
Have you ever try to set up a Kubernetes cluster manually by your own? It may be a small dish to you to set one up on your laptop. However, things are getting harder and harder once you have more nodes to handle, not to mention you also want security, monitoring, auto-scaling, and federated cluster enabled in the production environments. With more features added, the situation gets even worse and more complicated. We developers in Linker Networks had put in a tremendous amount of time in investigating on how to set up Kubernetes clusters efficiently. We designed and built our own tools to automate and facilitate such the painful processes. In this talk, I'll go through all the details and pitfalls in setting up a production ready cluster. Hopefully, the experience I shared could keep you out of these troubles, saving your precious time.

IPC16: A Practical Introduction to Kubernetes Robert Lemke
Kubernetes is an open source system for automating deployment, operations, and scaling of containerized applications. It’s one of the promising options you have for deploying your container-based applications to the Internet. In this session we’ll take a look at the concepts of Kubernetes and then go trough all steps necessary to launch and maintain a real-world PHP application in your own Kubernetes cluster.
Author: Oleg Chunikhin, www.eastbanctech.com
Kubernetes is a portable open source system for managing and orchestrating containerized cluster applications. Kubernetes solves a number of DevOps related problems out of the box in a simple and unified way – rolling updates and update rollback, canary deployment and other complicated deployment scenarios, scaling, load balancing, service discovery, logging, monitoring, persistent storage management, and much more. You will learn how in less than 30 minutes a reliable self-healing production-ready Kubernetes cluster may be deployed on AWS and used to host and operate multiple environments and applications.
A Million ways of Deploying a Kubernetes ClusterJimmy Lu
Developers and operators tend to build and develop different ways to set up a Kubernetes cluster due to its complexity and openness. Most of the time, it's quite confusing for the newcomers to get started with the Kubernetes. In this short talk, I'll introduce you some popular ways of Kubernetes deployment and briefly talk about pros and cons of each solution.

How to Migrate 100 Clusters from On-Prem to Google Cloud Without Downtimeloodse
Have you ever thought about migrating your Kubernetes clusters to Google Cloud to get your services closer to your customers? Yes? Us too! Join us on an interactive journey to discover the main challenges of live migration at scale of etcd’s, traffic routing and application workloads from your on-premise platform to GCP. The talk will discuss the current state of the technical concept, known problems and insides of the already proven migration steps for stateless workloads.
As part of the journey, we'll see
- The differences between migrating one or one hundred clusters with productive workloads
- What parts can be automated?
- What steps may need to be done manually?
KubeCon 2018 - Running VM Workloads Side by Side with Container Workloads loodse
On Kubernetes clusters, cloud native workloads and (legacy) VM workloads can run side by side. KubeVirt is a project to bring declarative, Kubernetes-style APIs to VM creation, configuration, and management. In this talk, I will demonstrate how you can use the KubeVirt to set up and manage VM inside of a Kubernetes cluster. I will be describing how KubeVirt leverages CPU virtualization to implement a stronger security architecture for Kubernetes.
When combining both approaches, we can run a wider range of workloads, from container cloud-native applications to lift-and-shift applications with KubeVirt.
