Terraform - scenarios with Managing Multiple Kubernetes Cluster Contexts in a Single Configuration
I'm trying to debug I'm currently working on a Terraform setup to manage multiple Kubernetes clusters, and I'm working with difficulties with context switching between them in a single configuration file. My goal is to create a modular approach where I can define different clusters and switch contexts based on the environment. However, I'm running into issues with the `kubernetes` provider configuration. Here's a simplified version of my Terraform code: ```hcl provider "kubernetes" { host = var.cluster_host token = var.cluster_token load_config_file = false } module "cluster_a" { source = "./modules/k8s_cluster" cluster_name = "cluster-a" } module "cluster_b" { source = "./modules/k8s_cluster" cluster_name = "cluster-b" } ``` In my `variables.tf`, I have: ```hcl variable "cluster_host" { description = "The host of the Kubernetes cluster" type = string } variable "cluster_token" { description = "Token for authentication" type = string } ``` The scenario I'm working with is that when I apply this configuration, Terraform seems to only recognize the context of the first cluster defined, ignoring the other modules. I see the following behavior in the output: ``` behavior: Unable to connect to the server: dial tcp: lookup cluster-a on 10.0.0.10:53: no such host ``` I tried setting different values for the `cluster_host` and `cluster_token` dynamically using locals and outputs, but it doesn't seem to switch contexts appropriately. I've also attempted to create separate provider instances with their own aliases, like: ```hcl provider "kubernetes" { alias = "cluster_a" host = var.cluster_a_host token = var.cluster_a_token } provider "kubernetes" { alias = "cluster_b" host = var.cluster_b_host token = var.cluster_b_token } ``` And then referencing them in my module calls. However, this leads to a conflict as Terraform warns that all modules must use the same provider. I'm looking for guidance on how to effectively manage multiple cluster contexts within a single Terraform configuration. Any best practices or strategies would be greatly appreciated! I'm using Terraform version 1.3.0 and the Kubernetes provider version 2.7.0. I'm coming from a different tech stack and learning Hcl. I'm open to any suggestions.
