redis.tf

outputs.tf

output "metricsAccessKey" {  value = var.metricsAccessKey} output "metricsSecretKey" {  value = var.metricsSecretKey} output "lokiBucket" {  value = var.lokiBucket} output "tempoBucket" {  value = var.tempoBucket} output "host" {  value = "minio.metrics.svc.cluster.local:9000"}

main.tf

provider "kubernetes" {  config_path = "${path.module}/../config.yaml"}  module "redis" {  source = "../modules/redis"}

apply

terraform initterraform apply --var-file=debug.tfvars 

再利用ダメ

module1.tf

resource "kubernetes_service" "module1" {  ...}

modules2.tf

module "module1" {  source = "../module1"}

modules3.tf

module "module1" {  source = "../module1"}

root-main.tf

module "module1" {  source = "../modules/module1"} module "module2" {  source = "../modules/module2"} module "module3" {  source = "../modules/module3"}
