Requirements

Providers

Name Version
aws >= 3.0
helm >= 1.0
kubernetes >= 1.11
local >=2.1.0

Nginx Ingress Controller

Based on https://kubernetes.github.io/ingress-nginx

For Example with TLS offload

module "nginx" {
  depends_on   = [module.sak-acm]
  source       = "https://github.com/provectus/sak-nginx.git"
  argocd       = module.argocd.state
  conf = {
    "controller.service.targetPorts.http"                                                                = "http"
    "controller.service.targetPorts.https"                                                               = "http"
    "controller.service.annotations.service\\.beta\\.kubernetes\\.io/aws-load-balancer-ssl-cert"         = module.clusterwide.this_acm_certificate_arn
    "controller.service.annotations.service\\.beta\\.kubernetes\\.io/aws-load-balancer-backend-protocol" = "http"
    "controller.service.annotations.service\\.beta\\.kubernetes\\.io/aws-load-balancer-ssl-ports"        = "https"
  }
  tags = {}
}

Example without SSL or with cert-manager

module "nginx" {
  source       = "github.com/provectus/sak-nginx.git"
  argocd       = module.argocd.state
  conf = {}
  tags = {}
}

Update version

  • Found the latest stable version of the helm chart from https://github.com/kubernetes/ingress-nginx/releases

  • Change the version in the default section, example: To test the SAK_NGINX module

  • Deploy SAK-NGINX by SAK (namespace ingress-system)

  • Deploy sample backend app:

kubectl create deployment web --image=registry.k8s.io/echoserver:1.4 --namespace ingress-system
kubectl expose deployment web --type=NodePort --port=8080 --namespace ingress-system
  • Get published hostname from column EXTERNAL-IP of ingress-Nginx: kubectl get svc -n ingress-system
  • Publish web app on ingress controller:
  • Check the web app from http://EXTERNAL-IP
