metallb VS ingress-nginx

Hey guys, I want to share a guide I’m pretty proud of which is talking about setting up kubernetes which leverages https://kubespray.io/#/ and https://metallb.universe.tf/ so you can host this yourself most people when spinning up kubernetes opt for k3s or get stuck with all the options or unable to setup the external ips for their services so these tools will eliminate the problem.

Have a closer look at MetallLB.

To avoid that, you can use a combination of haproxy and keepalived, an enterprise grade load balancer like the one from F5 or Citrix. Besides that you can also work with https://kube-vip.io or https://metallb.universe.tf.

Not sure if klipper is usable in a cluster with multiple nodes, as it binds to one port only. You may want to use MetalLB instead: https://metallb.universe.tf/

Then deploy MetalLB https://metallb.universe.tf/

What issue do you see with the load balancer? For self hosted clusters, one can use MetalLB for example to have such single outfacing IP which will failover to another node keeping the same IP if a node dies.

Quoting from their docs:

metalLB to manage bare-metal LoadBalancer services - WIP - Only L2 configuration can be set-up via playbook.

# Add NGINX ingress using Helm eks.HelmChart( self, "NginxIngress", cluster=cluster, chart="ingress-nginx", repository="https://kubernetes.github.io/ingress-nginx", namespace="ingress-nginx", values=helm_values )

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.
