terraform 是一个很不错的基础设施工具，我们可以用来做关于基础设施部署的事情，可以实现基础设施即代码
以下演示一个简单的自签名证书的生成（使用tls provider）

main.tf 文件

 
resource "tls_private_key" "example" {
  algorithm = "RSA"
}
resource "tls_self_signed_cert" "example" {
  key_algorithm = "${tls_private_key.example.algorithm}"
  private_key_pem = "${tls_private_key.example.private_key_pem}"
​
  # Certificate expires after 12 hours.
  validity_period_hours = 120000000
​
  # Generate a new certificate if Terraform is run within three
  # hours of the certificate's expiration time.
  early_renewal_hours = 30000000
  is_ca_certificate = true
  # Reasonable set of uses for a server SSL certificate.
  allowed_uses = [
      "key_encipherment",
      "digital_signature",
      "server_auth",
  ]
  ip_addresses = ["127.0.0.1","192.168.0.111","10.10.18.119"]
  dns_names = ["api.example.com", "k8sapi.example.com"]
​
  subject {
      common_name = "example.com"
      organization = "example, Inc"
  }
}
​
data "archive_file" "userinfos" {
  type = "zip"
  output_path = "tf-result/cert.zip"
  source {
    content = tls_private_key.example.private_key_pem
    filename = "private_key_pem"
  }
  source {
    content = tls_private_key.example.public_key_pem
    filename = "public_key_pem"
  }
  source {
    content = tls_self_signed_cert.example.cert_pem
    filename = "cert_pem"
  }
}
 

resource 说明

以上代码使用了archive provider 进行生成文件压缩，使用tls_private_key 生成私钥
使用tls_self_signed_cert 生成自签名证书

terraform plan

效果

Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.

"terraform apply" is subsequently run.
