错误:创建EC2实例:InvalidAMIID.Malformed:无效的id

Question

我想在aws上部署一个ec2实例。

这是我的资源代码

data "aws_ami_ids" "ubuntu" {
owners = ["099720109477"] 
filter {
name   = "name"
values = ["ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-*"]
}

filter {
name   = "virtualization-type"
values = ["hvm"]
}

}
output "test" {
value = data.aws_ami_ids.ubuntu
}
resource "aws_instance" "myec2" {
ami             = "${data.aws_ami_ids.ubuntu.id}"
instance_type   = var.instancetype
key_name        = "devops-era"`
security_groups = ["${aws_security_group.allow_http_https.name}"]
tags = {
Name =  "var.aws_common_tag" 
}  
}

但是当我运行terraform apply:

时，我一直得到下面的错误

Error: creating EC2 Instance: InvalidAMIID.Malformed: Invalid id: "203304658" (expecting "ami-...")
│   status code: 400, request id: 35b803fd-a6c8-4632-82ee-2936c9cbf062
│ 
│   with aws_instance.myec2,
│   on mini-projet.tf line 28, in resource "aws_instance" "myec2":
│   28: resource "aws_instance" "myec2" {

我不明白为什么

如有任何建议，我将不胜感激

您的数据源查询返回多个AMI id。你必须明确地选择你想要的，例如，使用第一个:

ami           = data.aws_ami_ids.ubuntu.ids[0]
