How to use

The module deploys and AKS cluster using Advanced Networking (Azure CNI with Custom VNET) and deploys using Helm nginx-ingress and cert-manager to the cluster. To call the module correctly use the following sample:

module "aks-nginx" {
  source = "github.com/evillgenius75/terraform-azurerm-aks-nginxingress"

        PROJECT="alt"
        INSTANCE="2"
        ENVIRONMENT="dev"
        REGION="southcentralUS"
        AKS_SSH_ADMIN_KEY="ssh-rsa AAAAB3NzaC1yc-----@----.local"
        ADMIN_USER="adminuser"
        NODE_COUNT="1"
        NODE_SIZE="Standard_D2s_v3"
        K8S_HELM_HOME="/Users/evill_genius/.helm"
        K8S_KUBE_CONFIG="/Users/evill_genius/.kube/test1"
        K8S_VER="1.13.5"
        VNET_NAME="aks-vnet"
}

There are more variables that are defaulted that can also be customized if needed such as(default Values shown):

VNET_ADDR_SPACE="10.10.0.0/16"
DNS_SERVERS=[]
SUBNET_NAMES=["aks-subnet"]
SUBNET_PREFIXES=["10.10.1.0/24"]
SERVICE_CIDR="10.0.0.0/16"
DNS_IP="10.0.0.10"
DOCKER_CIDR="172.17.0.1/16"
TILLER_VER="2.14.0"

The module uses local-exec assuming you are running from a bash shell. Tp determine the proper path for the K8S_HELM_HOME and K8S_KUBE_CONFIG variables you can type: helm home and the output should be the value for K8S_HELM_HOME. Your K8S_KUBE_CONFIG path should be the path to where you want the kube-config stored.

NOTE: To prevent overwriting your existing kube config please create a unique name for the actual config file. i.e. /Users/myUser/.kube/config-aks1

To enable the cert issuer you will just need to log in to the cluster and deploy a LetsEncrypt cert issuer yaml such as this:

apiVersion: certmanager.k8s.io/v1alpha1
kind: ClusterIssuer
metadata:
  name: letsencrypt-staging
spec:
  acme:
    # You must replace this email address with your own.
    # Let's Encrypt will use this to contact you about expiring
    # certificates, and issues related to your account.
    email: user@example.com
    server: https://acme-staging-v02.api.letsencrypt.org/directory
    privateKeySecretRef:
      # Secret resource used to store the account's private key.
      name: example-issuer-account-key
    # Add a single challenge solver, HTTP01 using nginx
    solvers:
    - http01:
        ingress:
          class: nginx
