Then use that computed property as input variable for whatever you want to deploy into Kubernetes.
We're using this with multiple providers and it works. Of course, an actual dependency that's visible would be better.
Here the module creates an EKS cluster, but this would work for any module that creates a k8s cluster.
module "my_cluster" {
source = "terraform-aws-modules/eks/aws"
version = "17.0.2"
cluster_name = "my-cluster"
cluster_version = "1.18"
}
# Queries for Kubernetes authentication
# this data query depends on the module my_cluster
data "aws_eks_cluster" "my_cluster" {
name = module.my_cluster.cluster_id
}
# this data query depends on the module my_cluster
data "aws_eks_cluster_auth" "my_cluster" {
name = module.my_cluster.cluster_id
}
# this provider depends on the data query above, which depends on the module my_cluster
provider "kubernetes" {
host = data.aws_eks_cluster.my_cluster.endpoint
cluster_ca_certificate = base64decode(data.aws_eks_cluster.my_cluster.certificate_authority.0.data)
token = data.aws_eks_cluster_auth.my_cluster.token
load_config_file = false
}
# this provider depends on the data query above, which depends on the module my_cluster
provider "helm" {
kubernetes {
host = data.aws_eks_cluster.my_cluster.endpoint
cluster_ca_certificate = base64decode(data.aws_eks_cluster.my_cluster.certificate_authority.0.data)
token = data.aws_eks_cluster_auth.my_cluster.token
load_config_file = false
}
}
# this resource depends on the k8s provider, which depends on the data query above, which depends on the module my_cluster
resource "kubernetes_namespace" "namespaces" {
metadata {
name = "my-namespace"
}
}
