I want to configure a simple nginx ingress resource in my k8s cluster. I'm happy to help. NGiNX has an excellent guide that I found that should help set up the ingress controller. They also have a GitHub page where you can post your problems or read about issues others had and how they fixed it. Lastly, I found NGiNX has a webinar showing how to get started with an ingress controller, but it looks like you will need to fill out their form to access it. I added the link in case you're interested. I hope this is enough information to help you get started. Please feel free to post any questions you have, and the Linode Community will do our best to help. You can use Markdown to format your question. Log in to Ask a Question.

Create an HTTPS ingress controller on Azure Kubernetes Service (AKS)


In this post I will explain, how I expose applications running on Kubernetes clusters to the internet with the help of Ingress controllers. But first a little bit about Kubernetes Ingresses and Services. On a very simplistic level a Service is a logical abstraction communication layer to pods. A important thing about services are what their type is, it determines how the service expose itself to the cluster or the internet. Some of the service types are :. This will be exposed to the internet. LoadBalancer Supported on Amazon and Google cloud, this creates the cloud providers your using load balancer. So on Amazon it creates a ELB that points to your service on your cluster. How do you expose everything to the internet? Enter Ingress Controllers. The ingress controller then picks up the new deployed service and proxy traffic to it from outside. Following this setup, you only have one ELB then on Amazon, and a central place at the ingress controller to manage the traffic coming into your cluster to your applications. Two of the more popular ones that I normally use, are Traefik and Nginx-ingress-controller. However as the projects needs grow or for more complex projects, I reach for the nginx-ingress-controller. Couple of differences between the two, that normally helps me decide which one to pick for a project. In general I prefer the nginx-ingress-controller, so for the rest of the article I will focus on it. The default backend is the default service that nginx falls backs to if if cannot route a request successfully. The default backend needs to satisfy the following two requirements :. Assuming you have SSL cert and key, create secrets as follow, where tsl. You might have noticed as well, we specify a default-backend-servicethis is used by nginx to route requests on which it found not ingress rule match. We need to deploy this default-backend-service before we deploy nginx. We can use the example default backend yaml file from the Kubernetes ingress github repo. After the deployment expose the default-http-backend so that the nginx-ingress-controller can communicate with it. What this command did was, it created a deployment with two replicas of the nginx-ingress-controller and a service for it of type LoadBalancer which created a ELB for us on AWS. Get the service :. This means the ELB on Amazon got created. Using the ELB hostname that we got from the querying for the nginx-ingress-controller service, make sure that traffic is being routed. This means everything is working correctly and the ELB forwarded traffic to our nginx-ingress-controller and the nginx-ingress-controller passed it along to the default-backend-service that we deployed. For the nginx-ingress-controller we are mostly interested in the ingress part.

Edit This Page. An Ingress is an API object that defines rules which allow external access to services in a cluster. An Ingress controller fulfills the rules set in the Ingress. You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by using Minikubeor you can use one of these Kubernetes playgrounds:. Launch Terminal. The next step lets you access the app using the Ingress resource. The following file is an Ingress resource that sends traffic to your Service via hello-world. Thanks for the feedback. If you have a specific, answerable question about how to use Kubernetes, ask it on Stack Overflow. Open an issue in the GitHub repo if you want to report a problem or suggest an improvement.

An ingress controller is a piece of software that provides reverse proxy, configurable traffic routing, and TLS termination for Kubernetes services. Kubernetes ingress resources are used to configure the ingress rules and routes for individual Kubernetes services. Using an ingress controller and ingress rules, a single IP address can be used to route traffic to multiple services in a Kubernetes cluster. The cert-manager project is used to automatically generate and configure Let's Encrypt certificates. Finally, two applications are run in the AKS cluster, each of which is accessible over a single IP address. This article assumes that you have an existing AKS cluster. Make sure that you are using the latest release of Helm. For upgrade instructions, see the Helm install docs. This article also requires that you are running the Azure CLI version 2. Run az --version to find the version. To create the ingress controller, use the helm command to install nginx-ingress. For added redundancy, two replicas of the NGINX ingress controllers are deployed with the --set controller. To fully benefit from running replicas of the ingress controller, make sure there's more than one node in your AKS cluster. The ingress controller also needs to be scheduled on a Linux node. Windows Server nodes currently in preview in AKS shouldn't run the ingress controller. A node selector is specified using the --set nodeSelector parameter to tell the Kubernetes scheduler to run the NGINX ingress controller on a Linux-based node. The following example creates a Kubernetes namespace for the ingress resources named ingress-basic. Specify a namespace for your own environment as needed. If you would like to enable client source IP preservation for requests to containers in your cluster, add --set controller. When using an ingress controller with client source IP preservation enabled, SSL pass-through will not work. During the installation, an Azure public IP address is created for the ingress controller. This public IP address is static for the life-span of the ingress controller. If you delete the ingress controller, the public IP address assignment is lost. If you then create an additional ingress controller, a new public IP address is assigned. If you wish to retain the use of the public IP address, you can instead create an ingress controller with a static public IP address. To get the public IP address, use the kubectl get service command. It takes a few minutes for the IP address to be assigned to the service.
