Kubernetes for Beginners: An Introductory GuideBytemark
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.

Container Network Interface: Network Plugins for Kubernetes and beyondKubeAcademy
With the rise of modern containers comes new problems to solve – especially in networking. Numerous container SDN solutions have recently entered the market, each best suited for a particular environment. Combined with multiple container runtimes and orchestrators available today, there exists a need for a common layer to allow interoperability between them and the network solutions.
As different environments demand different networking solutions, multiple vendors and viewpoints look to a specification to help guide interoperability. Container Network Interface (CNI) is a specification started by CoreOS with the input from the wider open source community aimed to make network plugins interoperable between container execution engines. It aims to be as common and vendor-neutral as possible to support a wide variety of networking options — from MACVLAN to modern SDNs such as Weave and flannel.
CNI is growing in popularity. It got its start as a network plugin layer for rkt, a container runtime from CoreOS. Today rkt ships with multiple CNI plugins allowing users to take advantage of virtual switching, MACVLAN and IPVLAN as well as multiple IP management strategies, including DHCP. CNI is getting even wider adoption with Kubernetes adding support for it. Kubernetes accelerates development cycles while simplifying operations, and with support for CNI is taking the next step toward a common ground for networking. For continued success toward interoperability, Kubernetes users can come to this session to learn the CNI basics.
This talk will cover the CNI interface, including an example of how to build a simple plugin. It will also show Kubernetes users how CNI can be used to solve their networking challenges and how they can get involved.

Building a scalable microservice architecture with envoy, kubernetes and istioSAMIR BEHARA
Talk from O'Reilly Software Architecture Conference San Jose 2019
Microservices and containers have taken the software industry by storm. Transitioning from a monolith to microservices enables you to deploy your application more frequently, independently, and reliably. However, microservice architecture has its own challenges, and it has to deal with the same problems encountered while designing distributed systems.
Enter service mesh technology to the rescue. A service mesh reduces the complexity associated with microservices and provides functionality like load balancing, service discovery, traffic management, circuit breaking, telemetry, fault injection, and more. Istio is one of the best implementations of a service mesh at this point, while Kubernetes provides a platform for running microservices and automating deployment of containerized applications.
Join Samir Behara to go beyond the buzz and understand microservices and service mesh technologies.

Scalable Service-Oriented Middleware over IPDai Yang
ABSTRACT
Due to the increased amount of communication in cars, a reliable and easy to use middleware system for automotive applications becomes a popular research field. In this paper, we review a recent approach: the Scalable Service-Oriented Middleware over IP (SOME/IP). We present current tech- nologies and how SOME/IP differs from them. We point out how SOME/IP is ordered into the ISO/OSI layer model and discuss its service orientation. We also present the ad- vantages and disadvantages of SOME/IP. In the end, we analyze its timing behavior and whether it is suitable for automotive software or not.
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.
Everyone heard about Kubernetes. Everyone wants to use this tool. However, sometimes we forget about security, which is essential throughout the container lifecycle.
Therefore, our journey with Kubernetes security should begin in the build stage when writing the code becomes the container image.
Kubernetes provides innate security advantages, and together with solid container protection, it will be invincible.
During the sessions, we will review all those features and highlight which are mandatory to use. We will discuss the main vulnerabilities which may cause compromising your system.

Load Balancing Apps in Docker Swarm with NGINXNGINX, Inc.
On-demand webinar recording: http://bit.ly/2mRjk2g
Docker and other container technologies continue to gain in popularity. We recently surveyed the broad community of NGINX and NGINX Plus users and found that two-thirds of organizations are either investigating containers, using them in development, or using them in production. Why? Because abstracting your applications from the underlying infrastructure makes developing, distributing, and running software simpler, faster, and more robust than ever before.
But when you move from running your app in a development environment to deploying containers in production, you face new challenges – such as how to effectively run and scale an application across multiple hosts with the performance and uptime that your customers demand.
The latest Docker release, 1.12, supports multihost container orchestration, which simplifies deployment and management of containers across a cluster of Docker hosts. In a complex environment like this, load balancing plays an essential part in delivering your container-based application with reliability and high performance.
Join us in this webinar to learn:
* The basic built-in load balancing options available in Docker Swarm Mode
* The pros and cons of moving to an advanced load balancer like NGINX
* How to integrate NGINX and NGINX Plus with Swarm Mode to provide an advanced load-balancing solution for a cluster with orchestration
* How to scale your Docker-based application with Swarm Mode and NGINX Plus
In this webinar we discuss new features in NGINX Plus R15, which includes support for gRPC, HTTP/2 Server Push, enhanced clustering, and OpenID Connect SSO integration.

An introductory look at Kubernetes and how it leverages AWS IaaS features to provide its own virtual clustering, and demonstration of some of the behaviour inside the cluster that makes Kubernetes a popular choice for microservice deployments.
This document provides an overview of a workshop on running Kubernetes on AWS. It outlines the prerequisites including installing Git, AWS CLI, kubectl, and cloning a GitHub repository. The workshop will cover basic Kubernetes concepts like pods, labels, replication controllers, deployments and services. It will demonstrate how to build a Kubernetes cluster on AWS using CloudFormation for infrastructure as code. Hands-on portions will include deploying containers, creating services, and observing the cluster architecture and networking. Additional topics are cluster add-ons like Kubernetes Dashboard and DNS, deploying applications, and cleaning up resources.
This document discusses service discovery in Docker using NGINX and NGINX Plus with Consul. It begins with an introduction to service discovery and why it is important for microservices applications. It then covers how open source NGINX integrates with Consul using Consul Template, noting limitations around increased memory usage.

Easily View, Manage, and Scale Your App Security with F5 NGINXNGINX, Inc.
Organizations typically use between 200 and 1,000 applications, many of them public facing and a direct gateway to customers and their data. While these apps enable critical functions, they’re also a common target for bad actors. A web application firewall (WAF) is a critical tool for securing apps by providing protection, detection, and mitigation against vulnerabilities and attacks. However, WAFs can be difficult to maintain and manage at scale. In this webinar, we explore how centralized visibility and configuration management of WAFs can decrease risk and save time.

Protecting Apps from Hacks in Kubernetes with NGINXNGINX, Inc.
Kubernetes has become the platform of choice for deploying modern applications. A Web Application Firewall (WAF) is the most common solution to providing run-time protection for applications (well, second most common, after blind -faith and protective amulets). The question is, how do you put a WAF in place for applications running on Kubernetes?
As for most IT questions, the obvious answer is, of course, “it depends.” But on what?
In this webinar, we look at how a WAF works, where to insert a WAF in your infrastructure, and the best way for a platform engineering team to create self-service WAF configuration on Kubernetes. We explore some sample configurations, and provide a demo of NGINX App Protect WAF in action.
Successfully Implement Your API Strategy with NGINXNGINX, Inc.

https://www.nginx.com/resources/webinars/successfully-implement-your-api-strategy-with-nginx/
About the Webinar
Cloud-native applications are distributed and decentralized by design, composed of dozens, hundreds, or even thousands of APIs connecting services deployed across cloud, on-premises, and edge environments. Without an effective API strategy in place, API sprawl quickly gets out-of-control and becomes unmanageable as the number of APIs in production outpaces your ability to govern and secure them.
In this webinar we explore trends that are accelerating API sprawl and look at some well-established best practices for managing, governing, and securing APIs in distributed environments. Our presenters also demo how to use API Connectivity Manager, part of F5 NGINX Management Suite, to streamline and accelerate your API operations.

How to Avoid the Top 5 NGINX Configuration Mistakes.pptxNGINX, Inc.
This document discusses common mistakes made in NGINX configuration and provides solutions. It covers:
1. Not setting enough file descriptors, which can cause application errors and error log entries. The recommended baseline is to set the max file handles to 2x the worker_connections.
2. Using the root directive inside location blocks, which is not secure. The root directive should be set at the server level and inherited.
3. Using the if directive in location contexts, which can cause problems and even crashes. It is better to use alternatives like try_files.
4. Confusion around directive inheritance, where directives are inherited "outside in." Array directives like add_header can unexpectedly override inherited values

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

◦ Provides delegated self-service configuration in a secure and managed
RBAC fashion
Note: This capability not supported in regular ingress resources
12
13. • L7 routing based on the host
header and URL
• TLS termination
• Requests matching a path is
delegated to one of two
VirtualServerRoute
definitions in the namespace
product-ns and solution-ns
respectively
VS CR Configuration
1. apiVersion: k8s.nginx.org/v1alpha1
2. kind: VirtualServer

Different approach Configuration style and approach
Defines a route for a virtual server, consisting of one or several subroutes.
We define a route with the path products and solutions, which is further defined in the VirtualServerRoute Definitions in the product-ns and solution-ns namespaces respectively.
Configuring Additional NGINX Features
Annotations are not part of the `spec` v(the spec part of the resource - the place where you define the load balancing configuration)
Annotations can grow bigger than specs
Annotations do not provide any type of safety in comparison to the spec (they are just key-value stores).
Annotations are bad at configuring complex rules (ex. Service A needs this feature with these parameters, while Service B needs the same feature with some different parameters)
it’s challenging to use the same annotation feature with different parameters for different services
Ingress:
Kubernetes Custom Resource
Automates configuration for an edge load balancer (or ADC)
Ingress features:
L7 routing based on the host header and URL
TLS termination
The configuration approach in release 1.5.0 – using custom resources – is a preview of our future direction. As we develop the next release (1.6.0), we welcome feedback, criticism, and suggestions for improvement to this approach. Once we’re satisfied we have a solid configuration architecture, we’ll lock it down and regard it as stable and fully production‑ready.
