Nginx Ingress Controller in Kubernetes

The Nginx Ingress Controller for Kubernetes provides enterprise-grade delivery services for Kubernetes applications, with benefits for users of both open-source Nginx and Nginx Plus.

With the Nginx Ingress Controller, you get basic load balancing, SSL/TLS termination, support for URI rewrites, and upstream SSL/TLS encryption.

50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

NGINX Announces Eight Solutions that Let Developers Run Safely with Scissors

Technology is hard. As technologists, I think we like it that way. It’s built‑in job security, right? Well, unfortunately, the modern application world has become unproductively hard. We need to make it easier.

That’s why I like describing the current developer paradox as the need to run safely with scissors.

NGINX Balances Developer Choice with Infrastructure Guardrails

Running with scissors is a simple metaphor for what is the admittedly difficult ask we make of software engineers. Developers need to run. Time to market and feature velocity are critical to the success of digital businesses. As a result, we don’t want to encumber developers with processes or technology choices that slow them down. Instead we empower them to pick tools and stacks that let them deliver code to customers as quickly as possible.

But there’s a catch. In the world of fast releases, multiple daily (or hourly or minutely!) changes, and fail‑fast development, we risk introducing application downtime into digital experiences – that risk is the metaphorical scissors that make it dangerous to run fast. On some level we know it’s wrong to make developers run with scissors. But the speed upside trumps the downtime downside.

That frames the dilemma of our era: we need our developers to run with scissors, but we don’t want anybody to get hurt. Is there a solution?

At NGINX, the answer is “yes”. I’m excited to announce eight new or significantly enhanced solutions built to unleash developer speed without sacrificing the governance, visibility, and control infrastructure teams require.

Load Balancing and Security DNS Solutions Empower Self‑Service

As my colleague, Gus Robertson, eloquently points out in his recent blog The Essence of Sprint Is Speed, self‑service is an important part of developer empowerment. He talks about developers as the engines of digital transformation. And if they’re not presented with easy-to-use, capable tools, they take matters into their own hands. The result is shadow IT and significant infrastructure risk.

Self‑service turns this on its head. It provides infrastructure teams with a way to release the application delivery and security technologies that developers need for A/B, canary, blue‑green, and circuit‑breaker patterns. But it does so within the guardrails that ensure the consistency, reliability, and security that ensure your apps remain running once in production.

Performance Testing NGINX Ingress Controllers in a Dynamic Kubernetes Cloud Environment

As more and more enterprises run containerized apps in production, Kubernetes continues to solidify its position as the standard tool for container orchestration. At the same time, demand for cloud computing has been pulled forward by a couple of years because work-at-home initiatives prompted by the COVID‑19 pandemic have accelerated the growth of Internet traffic. Companies are working rapidly to upgrade their infrastructure because their customers are experiencing major network outages and overloads.

To achieve the required level of performance in cloud‑based microservices environments, you need rapid, fully dynamic software that harnesses the scalability and performance of the next‑generation hyperscale data centers. Many organizations that use Kubernetes to manage containers depend on an NGINX‑based Ingress controller to deliver their apps to users.

Announcing NGINX Ingress Controller for Kubernetes Release 1.8.0

We are happy to announce release 1.8.0 of the NGINX Ingress Controller for Kubernetes. This release builds upon the development of our supported solution for Ingress load balancing on Kubernetes platforms, including Red Hat OpenShift, Amazon Elastic Container Service for Kubernetes (EKS), the Azure Kubernetes Service (AKS), Google Kubernetes Engine (GKE), IBM Cloud Private, Diamanti, and others.

With release 1.8.0, we continue our commitment to providing a flexible, powerful and easy-to-use Ingress Controller, which you can configure with both Kubernetes Ingress Resources and NGINX Ingress Resources:

• Kubernetes Ingress resources provide maximum compatibility across Ingress Controller implementations, and can be extended using annotations and custom templates to generate sophisticated configuration.
• NGINX Ingress resources provide an NGINX‑specific configuration schema, which is richer and safer than customizing the generic Kubernetes Ingress resources.

Release 1.8.0 brings the following major enhancements and improvements:

• Integration with NGINX App Protect – NGINX App Protect is the leading NGINX‑based application security solution, providing deep signature and structural protection for your web applications.
• Extensibility for NGINX Ingress resources – For users who want to use NGINX Ingress resources but need to customize NGINX features that the VirtualServer and VirtualServerRoute resources don’t currently expose, two complementary mechanisms are now supported: configuration snippets and custom templates.
• URI rewrites and request and response header modification – These features give you granular control (adding, removing, and ignoring) over the request and response headers that are passed to upstreams and then the ones that are passed back to the clients.
• Policies and IP address access control lists – With policies, traffic management functionality is abstracted within a separate Kubernetes object that can be defined and applied in multiple places by different teams. Access control lists (ACLs) are used to filter incoming and outgoing network traffic flowing through the NGINX Ingress Controller.
• Other new features –
• A readiness probe
• Support for multiple Ingress Controllers in VirtualServer and VirtualServerRoute resources and Helm charts
• Status information about VirtualServer and VirtualServerRoute resources
• Updates to the NGINX Ingress Operator for Red Hat OpenShift

Restricting Access By IP (Allow/Block Listing) using NGINX-Ingress Controller in Kubernetes

The demo aims at running an application in Kubernetes behind a Cloud-managed public load balancer also known as an HTTP(s) load balancer which is also known as an** Ingress resource** in Kubernetes dictionary. For this demo, I will be using Google Kubernetes Engine. Also, instead of using a default ingress controller that GCP makes of its own, I will be creating an NGINX ingress controller which will be used by the Ingress resource. Using this NGINX ingress controller we will be allowing IP addresses and eventually blocking others from accessing our application running in GKE. Before we start with the implementation, let us get some of our prerequisites revised.

What is Ingress in Kubernetes?

In Kubernetes, an Ingress is an object or a resource that allows access to your Kubernetes services from outside the Kubernetes cluster. One can configure access by creating a collection of rules that define which inbound connections can reach which services. In GKE, when we specify kind: Ingress in the resource manifest. GKE then creates an Ingress resource making appropriate Google Cloud API calls to create an external HTTP(S) load balancer. The load balancer’s URL maps host rules and path matches, to refer to one or more backend services, where each backend service corresponds to a GKE Service of type NodePort, as referenced in the Ingress.

But then……

What is Ingress Controller in Kubernetes?

For the Ingress resource to work, the cluster must have an ingress controller running. There multiple Ingress controllers available and they can be configured with the Ingress resource eg. NGINX Ingress Controller, HAproxy Ingress controller, Traefik, Contour, etc.

We will be using the NGINX Ingress Controller for the demo.

So now……
