ingress-nginx VS k8s-helm-helmfile

ingress-nginx

The second one is a combination of tools: External DNS, cert-manager, and NGINX ingress. Using these as a stack, you can quickly deploy an application, making it available through a DNS with a TLS without much effort via simple annotations. When I first discovered External DNS, I was amazed at its quality.

resource "helm_release" "icrelease" { name = "nginx-ingress" repository = "https://kubernetes.github.io/ingress-nginx" chart = "ingress-nginx" version = "4.9.1" namespace = kubernetes_namespace.icnamespace.metadata[0].name set { name = "controller.ingressClassResource.default" value = "true" } }

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx helm repo update helm upgrade --install ingress-nginx ingress-nginx/ingress-nginx --namespace ingress-nginx --create-namespace -f custom/ghost/nginx.yaml

For example, if you chose Nginx Ingress, you will use some of its dozens of annotations that are not portable if you decide to switch to another Ingress implementation like Apache APISIX.

The controller is installed with helm upgrade --install ingress-nginx ingress-nginx --repo https://kubernetes.github.io/ingress-nginx --namespace ingress-nginx --create-namespace

helm repo add jetstack https://charts.jetstack.io helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx helm repo add rancher-latest https://releases.rancher.com/server-charts/latest helm repo update helm repo list

Everything in the YAML snippets below — except for ingress configuration — relates to configuring the NGINX ingress controller. This includes customizing the default configuration.

Keep Documentation Handy: Always have the official NGINX Ingress documentation accessible.

First of all you need a GitHub repository to hold our YAML files. I'm using my old project - k8s-helm-helmfile. This repository has three folders, each containing a different approach to deploy applications into Kubernetes clusters. You can read more about those approaches in my previous blog posts about vanilla K8s, Helm and helmfile deployments.

They contain definitions of ConfigMap, Deployment, PersistentVolumeClaim and ClusterIP. Their full definitions could be found in a repository.
