[英]Terraform Import aws security group resources created using terraform-aws-modules/security-group/aws//modules/web
[英]AWS Load Balancer Terraform module (https://github.com/terraform-aws-modules/terraform-aws-alb): target_group_index = 0, what is it?
我嘗試使用模塊 AWS 應用程序和網絡負載均衡器(ALB 和 NLB)Terraform 模塊https://github.com/terraform-aws-modules/terraform-aws-alb 。 有一個 Application Load Balancer 的示例用法,見下文:
module "alb" {
source = "terraform-aws-modules/alb/aws"
version = "~> 5.0"
name = "my-alb"
load_balancer_type = "application"
vpc_id = "vpc-abcde012"
subnets = ["subnet-abcde012", "subnet-bcde012a"]
security_groups = ["sg-edcd9784", "sg-edcd9785"]
access_logs = {
bucket = "my-alb-logs"
}
target_groups = [
{
name_prefix = "pref-"
backend_protocol = "HTTP"
backend_port = 80
target_type = "instance"
}
]
https_listeners = [
{
port = 443
protocol = "HTTPS"
certificate_arn = "arn:aws:iam::123456789012:server-certificate/test_cert-123456789012"
target_group_index = 0
}
]
http_tcp_listeners = [
{
port = 80
protocol = "HTTP"
target_group_index = 0
}
]
tags = {
Environment = "Test"
}
}
我知道 target_groups 是一個數組。 但是,為什么 target_group_index = 0 而不是 target_group_index = 1 或 target_group_index = 2? 什么是指數 0?
在您發布的示例中,只有一個目標組(TG):
target_groups = [
{
name_prefix = "pref-"
backend_protocol = "HTTP"
backend_port = 80
target_type = "instance"
}
]
因此,偵聽器使用target_group_index = 0
來指示它們適用於這個特定的 TG。 如果您有更多的 TG,您將使用target_group_index = 1, 2, 3 ...
來指定適用於每個 TG 的偵聽器。
