amazon-web-services - プライベート サブネットワーク上の 2 つ以上のノード間の Terraform AWS ルーティング

Question

AWS のプライベート VPC にいくつかのノードを作成する terraform プラン (以下) があります。すべてがうまくいっているように見えますが、VPC 内のノード間で ssh または ping を実行できません。

プライベート ネットワーク内の 2 つのノードが互いに通信できるようにするために、次の構成に欠けているものは何ですか?

provider "aws" {
  region = "${var.aws_region}"
  access_key = "${var.aws_access_key}"
  secret_key = "${var.aws_secret_key}"
}

  # The connection block tells our provisioner how to communicate with the
