Deep dive into Kubernetes Networking

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, a container orchestration system. It begins with background on Docker containers and orchestration tools prior to Kubernetes. It then covers key Kubernetes concepts including pods, labels, replication controllers, and services. Pods are the basic deployable unit in Kubernetes, while replication controllers ensure a specified number of pods are running. Services provide discovery and load balancing for pods. The document demonstrates how Kubernetes can be used to scale, upgrade, and rollback deployments through replication controllers and services.

Presented as part of Container Conference 2018: www.containerconf.in Deep dive into Kubernetes networking "Container networking is pretty complex and Kubernetes has taken a unique approach to solve container networking challenges. Both simplicity and scalability have been key design principles of Kubernetes networking. This session will illustrate kubernetes networking concepts with examples and demos. Best practises and considerations for deploying container networks in production using Kubernetes will be covered. This session will also go into latest developments in Kubernetes networking like Network policy and Service policy using Istio."

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It coordinates activities across a cluster of machines by defining basic building blocks like pods (which contain containers), replication controllers (which ensure a specified number of pods are running), and services (which define logical groups of pods). Kubernetes provides tools for running applications locally on a single node as well as managing resources in the cluster, including creating, deleting, viewing, and updating resources from configuration files.

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.

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.

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.

Those are the slides that were used to give an introduction to Kubernetes at the Nardoz Berlin Meetup on the 2018-06-28.

A basic introductory slide set on Kubernetes: What does Kubernetes do, what does Kubernetes not do, which terms are used (Containers, Pods, Services, Replica Sets, Deployments, etc...) and how basic interaction with a Kubernetes cluster is done.

This document provides an introduction to Kubernetes, an open-source system for automating deployment, scaling, and management of containerized applications. It first reviews what Docker is and its features like isolation and compatibility across platforms. It then explains that container orchestration is needed to manage thousands of containers across a cluster, ensure efficient resource use, and automate container lifecycles. Kubernetes is recommended because it is actively developed by major companies, makes scheduling and managing workloads easy through features like rolling updates, and has many extensions available.

OpenShift cloud technology high-level overview given at the Athens Area Software Developer Meet-up in Athens, Georgia, January 2014.

An in depth overview of Kubernetes and it's various components. NOTE: This is a fixed version of a previous presentation (a draft was uploaded with some errors)

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.

Incredibly powerful and flexible, Kubernetes role-based access control (RBAC) is an essential tool to effectively manage production clusters. Yet many Ops and DevOps engineers are still facing barriers to efficiently use it at scale. These include a steep learning curve, YAML-based configuration, lack of standardized best practices, and the general complexity of this functionality at large -- it truly can be somewhat overwhelming. During this meetup Oleg, CTO at Kublr, will discuss Kubernetes RBAC concepts and objects. He'll explore different use cases ranging from simple permission management for in-cluster application accounts to integrations with external identity providers for SSO and enterprise user access management. Leveraging the Kublr Platform, Oleg will demonstrate how it simplifies the management of access and RBAC rules in a cloud native environment while staying vendor-independent and compatible with any Kubernetes distribution.

Unique course notes for the Certified Kubernetes Administrator (CKA) for each section of the exam. Designed to be engaging and used as a reference in the future for kubernetes concepts.

This document discusses building a SDN solution for deploying web application stacks in Docker containers. It proposes developing a wSDN network plugin driver for Docker's libnetwork that implements the Docker plugin API and network driver protocol. This would allow wSDN to manage container networking and provide features like multi-host networking, IP address management, and tenant isolation across multiple data centers. It also discusses Docker's existing networking limitations and outlines requirements for a SDN solution to address Docker's needs for large web application deployments in a multi-tenant environment.

The document provides an overview of the Kubernetes Gateway API, which enables robust traffic management in Kubernetes clusters. It describes key concepts like GatewayClasses, Gateways, and Routes that make up the Gateway API model. The API allows infrastructure providers to implement ingress controllers, cluster operators to manage traffic, and application developers to define routing rules in a standardized way. It aims to improve on the Ingress resource and support multiple protocols like HTTP, TLS, and TCP in an integrated manner. There are now over a dozen implementations of the Gateway API by popular API gateways and service meshes.
