“”不是有效的 CIDR 块：无效的 CIDR 地址

Question

我在 terraform 中定义了一个 VPC：

\n

//vpc.tf\nresource "aws_vpc" "my_vpc" {\n  cidr_block = "10.0.0.0/16"\n}\n\n

\n

我正在尝试创建一个安全组：

\n

// securityGroup.tf\nresource "aws_security_group" "allow_tls" {\n  name        = "allow_tls"\n  description = "Allow TLS inbound traffic"\n  vpc_id      = aws_vpc.my_vpc.id\n  ingress {\n    description      = "TLS from VPC"\n    from_port        = 443\n    to_port          = 443\n    protocol         = "tcp"\n    cidr_blocks      = [aws_vpc.my_vpc.cidr_block]\n    ipv6_cidr_blocks = [aws_vpc.my_vpc.ipv6_cidr_block]\n  }\n  egress {\n    from_port        = 0\n    to_port          = 0\n    protocol         = "-1"\n    cidr_blocks      = ["0.0.0.0/0"]\n    ipv6_cidr_blocks = ["::/0"]\n  }\n}\n

\n

然而，当我跑步时terraform plan出现错误Error: "" is not a valid CIDR block: invalid CIDR address:

\n

我认为cidr_block我的 vpc 中定义的内容可供 securityGroup 使用，但事实似乎并非如此。如何正确引用cidr_block从我的 vpc 中正确引用？

完整的错误输出：

您尚未为您的 VPC 配置任何 IPV6 地址。因此，您的安全组中的这一行应该被删除：

ipv6_cidr_blocks = [aws_vpc.my_vpc.ipv6_cidr_block]
