Terraform module to create application load balancer
terrafrom module config example:
module "starmine_api_ecs_task_service_alb_primary" {
count = local.lb_count
source = "../.."
load_balancer_name = local.lb_name
target_group_name = local.lb_name
vpc_id = var.vpc_id
subnet_ids = var.subnet_ids
internal = true
http_port = "80"
target_group_port = "8080"
health_check_path = "/research-analytics/starmine/beta1/actuator/health"
health_check_matcher = "200"
labels = merge(local.labels, { component = "alb-enterprise" }, ) //use alb as component name for better naming
}
