I am trying to get ingress EXTERNAL-IP in k8s. Is there any way to get the details from terraform data block. like using data "azurerm_kubernetes_cluster" or something?
The solution that pops into my head (which I'm sure is not the ideal one) is to use local-exec, and then use kubectl to interrogate the ingress resource in-cluster to get the IP.
Something like this (caveat: haven't tested it and I don't use AKS, so I don't know for sure if it'll work as expected)
resource "null_resource" "example1" {
provisioner "local-exec" {
command = "kubectl get ingress name-of-ingress-controller-lb | jq .status.loadBalancer.ingress[0].ip"
}
}
you can create the Public IP in advance with terraform and assign this IP to your ingress service:
YAML:
apiVersion: v1
kind: Service
metadata:
annotations:
service.beta.kubernetes.io/azure-load-balancer-resource-group: myResourceGroup # only needed if the LB is in another RG
name: ingress-nginx-controller
spec:
loadBalancerIP: <YOUR_STATIC_IP>
type: LoadBalancerSame but Terraform code:
resource "kubernetes_service" "ingress_nginx" {
metadata {
name = "ingress-nginx-controller"
annotations {
"service.beta.kubernetes.io/azure-load-balancer-resource-group" = "${azurerm_resource_group.YOUR_RG.name}"
}
spec {
selector = {
app = <PLACEHOLDER>
}
port {
port = <PLACEHOLDER>
target_port = <PLACEHOLDER>
}
type = "LoadBalancer"
load_balancer_ip = "${azurerm_public_ip.YOUR_IP.ip_address}"
}
}
