Kubernetes Networking 101

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It was originally developed by Google based on years of experience running production workloads at scale. Kubernetes groups containers into logical units called pods and handles tasks like scheduling, health checking, scaling and rollbacks. The main components include a master node that manages the cluster and worker nodes that run application containers scheduled by the master.

In the era of Microservices, Cloud Computing and Serverless architecture, it’s useful to understand Kubernetes and learn how to use it. However, the official Kubernetes documentation can be hard to decipher, especially for newcomers. In this book, I will present a simplified view of Kubernetes and give examples of how to use it for deploying microservices using different cloud providers, including Azure, Amazon, Google Cloud and even IBM.

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.

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. Its main components include a master node that manages the cluster and worker nodes that run the applications. It uses labels to identify pods and services and selectors to group related pods. Common concepts include deployments for updating apps, services for network access, persistent volumes for storage, and roles/bindings for access control. The deployment process involves the API server, controllers, scheduler and kubelet to reconcile the desired state and place pods on nodes from images while providing discovery and load balancing.

Cilium is open source software for providing and transparently securing network connectivity and load balancing between application workloads such as application containers or processes. Cilium operates at Layer 3/4 to provide traditional networking and security services as well as Layer 7 to protect and secure use of modern application protocols such as HTTP, gRPC and Kafka. The foundation of Cilium is the new Linux kernel technology BPF which supports the dynamic insertion of BPF bytecode into the Linux kernel at various integration points. This presentation reveals the secrets of Kubernetes networking and gives you a deep dive into Cilium and why it is awesome!

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 provides an overview of Kubernetes concepts and architecture. It begins with an introduction to containers and microservices architecture. It then discusses what Kubernetes is and why organizations should use it. The remainder of the document outlines Kubernetes components, nodes, development processes, networking, and security measures. It provides descriptions and diagrams explaining key aspects of Kubernetes such as architecture, components like Kubelet and Kubectl, node types, and networking models.

If you’re working with just a few containers, managing them isn't too complicated. But what if you have hundreds or thousands? Think about having to handle multiple upgrades for each container, keeping track of container and node state, available resources, and more. That’s where Kubernetes comes in. Kubernetes is an open source container management platform that helps you run containers at scale. This talk will cover Kubernetes components and show how to run applications on it.

This document provides an overview of Kubernetes basics. It introduces Kubernetes as an open source container orchestration tool developed by Google to manage the lifecycle of containers. It describes common Kubernetes concepts like pods, deployments, services, and how to install Kubernetes on local, on-premise and cloud environments. It also covers important topics for production use such as health checks, resource restrictions, logging, monitoring and alerts.

This document provides an overview of OpenShift Container Platform. It describes OpenShift's architecture including containers, pods, services, routes and the master control plane. It also covers key OpenShift features like self-service administration, automation, security, logging, monitoring, networking and integration with external services.

The document provides an overview of Docker networking as of version 17.06. It begins with introductions of the presenter and some key terminology used. It then discusses why container networking is needed and compares features of container and VM networking. The major components of Docker networking including network drivers, IPAM, Swarm networking, service discovery, and load balancing are outlined. Concepts of CNI/CNM standards and IP address management are explained. Examples of different network drivers such as bridge, overlay, macvlan are provided. The document also covers Docker networking concepts such as default networks, Swarm mode, service discovery, and load balancing. It concludes with some debugging commands and a reference slide.

This document provides an overview of Kubernetes including: - Kubernetes is an open source system for managing containerized applications and services across clusters of hosts. It provides tools to deploy, maintain, and scale applications. - Kubernetes objects include pods, services, deployments, jobs, and others to define application components and how they relate. - The Kubernetes architecture consists of a control plane running on the master including the API server, scheduler and controller manager. Nodes run the kubelet and kube-proxy to manage pods and services. - Kubernetes can be deployed on AWS using tools like CloudFormation templates to automate cluster creation and management for high availability and scalability.

This document provides an introduction to Kubernetes, including definitions of key concepts like pods, services, labels, replica sets, deployments, and horizontal pod autoscaling. It explains how Kubernetes abstracts and virtualizes resources to run and manage containers across a cluster. Examples and diagrams illustrate concepts like pod networking and canary deployments. The document recommends resources for learning more about Kubernetes and getting started, including Google Cloud Platform and a demo of Kubernetes capabilities.

This document discusses OpenShift Container Platform, a platform as a service (PaaS) that provides a full development and deployment platform for applications. It allows developers to easily manage application dependencies and development environments across basic infrastructure, public clouds, and production servers. OpenShift provides container orchestration using Kubernetes along with developer tools and a user experience to support DevOps practices like continuous integration/delivery.
