使用terraform连接运行aws实例

Question

resource "aws_instance" "appserver1" {
ami             = var.imageid
instance_type   = var.instancetype
key_name        = var.key
security_groups = [aws_security_group.allow_all.name]
connection {
user        = "ubuntu"
private_key = file(var.privatekeypath)
}
provisioner "remote-exec" {
inline = [
"sudo apt-get update",
"sudo apt-get install tomcat7 -y"
]
}
}

"起程拓殖validate"给我错误:

错误:缺少必需的参数

主要。第52行，在资源"aws_instance"appserver1"52:连接{

参数"host"，但是没有找到定义。

Answer 1

您必须在provisioner块中指定连接细节。例如:

resource "aws_instance" "appserver1" {
ami             = var.imageid
instance_type   = var.instancetype
key_name        = var.key
security_groups = [aws_security_group.allow_all.name]

provisioner "remote-exec" {
connection {
type        = "ssh"
user        = "ubuntu"
private_key = file(var.privatekeypath)
host        = self.public_ip
}
inline = [
"sudo apt-get update",
"sudo apt-get install tomcat7 -y"
]
}
}

但是在您的情况下，使用user_data会更合适。

Answer 2

在启动部署实例时，可以使用userdataEC2 userdata选项来安装tomcat，而不是使用连接。

我不认为在实例配置中提供连接块会起作用
