Ingress with Treafik on K3s

This post is a tutorial on how to expose a website hosted with nginx by using the K3s built-in ingress controller “Traefik”.

It is based on my last post

The result of this post was an “empty” cluster without any “useful” services. In my first post on installing K3s I have created an ingress controller based on HAProxy. At that time I was not aware that K3s already comes with an ingress controller all up and running.

This time, four resources are needed

  • Config Map
  • Deployment
  • Services
  • Ingress

The config map is a quick and dirty way of making it possible for nginx to access the html-file. It is not a clean way of hosting a website and is used just for this purpose.

Ingress with Treafik on K3s

Kubernetes Ingress - All you need to know!

What is Kubernetes Ingress?

Kubernetes Ingress is a k8 API object that orchestrates and decides the exposure of all the external access to services defined within the cluster. That is, it routes the traffic and controls the same through the resource.

Ingress manages the external exposure and access to the services basically HTTP and HTTPS routes. It is termed useful mostly when we want to have some external HTTP(s) connections to expose it to the services or applications within the pods inside the cluster. For the same, we configure the ingress resource to the services through external DNS-wise URLs, load-balancers, etc.

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.

Supporting the Evolving Ingress Specification in Kubernetes 1.18

What is Kubernetes Ingress

When deploying your applications in Kubernetes, one of the first challenges many people encounter is how to get traffic into their cluster. Kubernetes ingress is a collection of routing rules that govern how external users access services running in a Kubernetes cluster. There are three general approaches for exposing your application:

  • Using a NodePort to expose your application on a port across each of your nodes
  • Using a LoadBalancer service to create an external load balancer that points to a Kubernetes service in your cluster
  • Using a Kubernetes Ingress resource

What’s new in Kubernetes 1.18 Ingress

There are three significant additions to the Ingress API in Kubernetes 1.18:

  • A new pathType field
  • A new IngressClass resource
  • Support for wildcards in hostnames

The new pathType field allows you to specify how Ingress paths should match. The field supports three types: ImplementationSpecific (default), exact, and prefix. Explicitly defining the expected behavior of path matching will allow every ingress-controller to support a user’s needs and will increase portability between ingress-controller implementation solutions.

The IngressClass resource specifies how Ingresses should be implemented by controllers. This was added to formalize the commonly used but never standardized kubernetes.io/ingress.class annotation and allow for implementation-specific extensions and configuration.

You can read more about these changes, as well as the support for wildcards in hostnames in more detail in a previous blog post.

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.
