ECS 和负载均衡器的 Terraform 第一次失败
Terraform fails first time for ECS and Load Balancer
我正在使用 Terraform 部署带有负载均衡器的 ECS 集群。我的 Terraform 代码如下:
resource "aws_lb" "my_lb" {
name = format("%s-my-lb", var.name)
internal = false
load_balancer_type = "application"
security_groups = [var.lb_security_groups_id]
subnets = var.public_subnet_id
}
...
resource "aws_lb_target_group" "my_tg" {
name = format("%s-my-tg", var.name)
port = 80
protocol = "HTTP"
target_type = "ip"
vpc_id = var.vpc_id
}
...
resource "aws_lb_listener" "my_listener" {
load_balancer_arn = aws_lb.my_lb.arn
port = "80"
protocol = "HTTP"
default_action {
type = "forward"
target_group_arn = aws_lb_target_group.my_tg.arn
}
}
ECS 服务与 LoadBalancer 链接如下:
resource "aws_ecs_service" "my_ecs_service" {
name = format("%s-ecs-service", var.name)
...
...
load_balancer {
target_group_arn = aws_lb_target_group.my_tg.arn
container_name = "my-container"
container_port = 80
}
}
当我应用 Terraform 时,它会创建负载平衡器、目标组和侦听器。但是,在创建ECS服务之前,它会抛出这个错误:
...

当我第二次应用这个 terraform 而不做任何更改时,它将完美地工作。不知道为什么第一次失败
我该如何解决这个问题?
这通常意味着您需要明确定义与 ALB 的 depends_on
关系。随后,您可以尝试以下操作:
resource "aws_lb_target_group" "my_tg" {
name = format("%s-my-tg", var.name)
port = 80
protocol = "HTTP"
target_type = "ip"
vpc_id = var.vpc_id
depends_on = [aws_alb.my_lb]
}
