我尝试使用 Terrafom 部署 EC2 实例，但看到以下错误：

Error: Error launching source instance: InvalidGroup.NotFound: The security group 'prod-web-servers-sg' does not exist in VPC 'vpc-db3a3cb3'

这是我正在使用的 Terraform 模板：

resource "aws_default_vpc" "default" {
}

resource "aws_security_group" "prod-web-servers-sg" {
name        = "prod-web-servers-sg"
description = "security group for production grade web servers"
vpc_id      = "${aws_default_vpc.default.id}"

ingress {
from_port   = 80
to_port     = 80
protocol    = "tcp"
cidr_blocks = ["0.0.0.0/0"]
}
ingress {
from_port   = 443
to_port     = 443
protocol    = "tcp"
cidr_blocks = ["0.0.0.0/0"]
  }
}

我正在尝试在 Kubernetes 中使用 Helm 配置 Prometheus，并尝试执行如下命令并且部署成功。

$ helm install prometheus prometheus-community/prometheus --namespace prometheus --set 
nodeSelector.nodetype=infra
NAME: prometheus
LAST DEPLOYED: Tue Apr 27 22:47:20 2021
NAMESPACE: prometheus
STATUS: deployed

但是，当我尝试描述创建的 Pod 时，我无法将 NodeSelector 值视为“nodetype=infra”。有人可以指出我错过的地方吗？
