Kubernetes is an open-source tool for managing containerized workloads and services. It allows for deploying, maintaining, and scaling applications across clusters of servers. Kubernetes operates at the container level to automate tasks like deployment, availability, and load balancing. It uses a master-slave architecture with a master node controlling multiple worker nodes that host application pods, which are groups of containers that share resources. Kubernetes provides benefits like self-healing, high availability, simplified maintenance, and automatic scaling of containerized applications.

OpenShift Virtualization allows running virtual machines as containers managed by Kubernetes. It uses KVM with QEMU and libvirt to run virtual machines inside containers. Virtual machines are scheduled and managed like pods through Kubernetes APIs and can access container networking and storage. Templates can be used to simplify virtual machine creation and configuration. Virtual machines can be imported, viewed, managed, and deleted through the OpenShift console and CLI like other Kubernetes resources. Metrics on virtual machine resources usage are also collected.

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery called Pods. ReplicaSets ensure that a specified number of pod replicas are running at any given time. Key components include Pods, Services for enabling network access to applications, and Deployments to update Pods and manage releases.

This document provides an overview of Kubernetes, an open-source system for automating deployment, scaling, and management of containerized applications. It describes Kubernetes' architecture including nodes, pods, replication controllers, services, and networking. It also discusses how to set up Kubernetes environments using Minikube or kubeadm and get started deploying pods and services.

The document discusses Kubernetes networking. It describes how Kubernetes networking allows pods to have routable IPs and communicate without NAT, unlike Docker networking which uses NAT. It covers how services provide stable virtual IPs to access pods, and how kube-proxy implements services by configuring iptables on nodes. It also discusses the DNS integration using SkyDNS and Ingress for layer 7 routing of HTTP traffic. Finally, it briefly mentions network plugins and how Kubernetes is designed to be open and customizable.

Traditional virtualization technologies have been used by cloud infrastructure providers for many years in providing isolated environments for hosting applications. These technologies make use of full-blown operating system images for creating virtual machines (VMs). According to this architecture, each VM needs its own guest operating system to run application processes. More recently, with the introduction of the Docker project, the Linux Container (LXC) virtualization technology became popular and attracted the attention. Unlike VMs, containers do not need a dedicated guest operating system for providing OS-level isolation, rather they can provide the same level of isolation on top of a single operating system instance. An enterprise application may need to run a server cluster to handle high request volumes. Running an entire server cluster on Docker containers, on a single Docker host could introduce the risk of single point of failure. Google started a project called Kubernetes to solve this problem. Kubernetes provides a cluster of Docker hosts for managing Docker containers in a clustered environment. It provides an API on top of Docker API for managing docker containers on multiple Docker hosts with many more features.

This document provides an agenda and instructions for a hands-on introduction to Kubernetes tutorial. The tutorial will cover Kubernetes basics like pods, services, deployments and replica sets. It includes steps for setting up a local Kubernetes environment using Minikube and demonstrates features like rolling updates, rollbacks and self-healing. Attendees will learn how to develop container-based applications locally with Kubernetes and deploy changes to preview them before promoting to production.

This document discusses upgrading an Openstack network to SDN with Tungsten Fabric. It evaluates three solutions: 1) using the same database across regions, 2) hot-swapping Open vSwitch and virtual routers, and 3) using an ML2 plugin. The recommended solution is #3 as it provides minimum downtime. Key steps include installing the OpenContrail driver, synchronizing network resources between Openstack and Tungsten, and live migrating VMs. Topology 2 is also recommended as it requires minimum changes. The upgrade migrated 80 VMs and 16 compute nodes to the SDN network without downtime. Issues discussed include synchronizing resources and migrating VMs between Open vSwitch and virtual routers.

Kubespray and Ansible can be used to automate the installation of Kubernetes in a production-ready environment. Kubespray provides tools to configure highly available Kubernetes clusters across multiple Linux distributions. Ansible is an IT automation tool that can deploy software and configure systems. The document then provides a 6 step guide for installing Kubernetes on Ubuntu using kubeadm, including installing Docker, kubeadm, kubelet and kubectl, disabling swap, configuring system parameters, initializing the cluster with kubeadm, and joining nodes. It also briefly explains Kubernetes architecture including the master node, worker nodes, addons, CNI, CRI, CSI and key concepts like pods, deployments, networking,

KubeVirt is intended to provide a convergence point for the data center of the future using Kubernetes as an infrastructure fabric for both application container and virtual machine workloads. Using a unified management approach simplifies deployments, allows for better resource utilization, and supports different workloads in a more optimal way. This session will outline how the Kubevirt project seeks to achieve this while using the extensible nature of Kubernetes in a way that provides a developer workflow that is as consistent as possible with the same patterns used for working with application containers.
