我正在尝试使用 Terraform 创建一个自签名证书，以便在测试/开发环境中内部使用。

我首先创建一个 CA 私钥，自签名证书。

然后，我为要为其启用 HTTPS 的内部域名创建证书签名请求和私钥。

然后我签署证书。这是我使用的整个 Terraform 清单：

resource "tls_private_key" "ca" {
  algorithm = "ECDSA"
  ecdsa_curve = "P384"
}

resource "tls_self_signed_cert" "ca" {
  key_algorithm = "${tls_private_key.ca.algorithm}"
  private_key_pem = "${tls_private_key.ca.private_key_pem}"

  subject {
    common_name = "Example CA"
    organization = "Example, Ltd"
    country = "GB"
  }

  validity_period_hours = 43800
  is_ca_certificate = true

  allowed_uses = [
    "key_encipherment",
    "digital_signature",
    "server_auth",
    "client_auth",
  ]
}

resource "tls_private_key" "registry" {
  algorithm = "ECDSA"
  ecdsa_curve = "P384"
}

resource "tls_cert_request" "registry" {
  key_algorithm = "${tls_private_key.registry.algorithm}"
  private_key_pem = "${tls_private_key.registry.private_key_pem}"

  subject {
    common_name = "registry.test.example.com"
    organization = "Example, Ltd"
    country = "GB"
  }

  dns_names = ["registry.test.example.com"]
}

resource "tls_locally_signed_cert" "registry" {
  cert_request_pem = "${tls_cert_request.registry.cert_request_pem}"

  ca_key_algorithm = "${tls_private_key.ca.algorithm}"
  ca_private_key_pem = "${tls_private_key.ca.private_key_pem}"
  ca_cert_pem = "${tls_self_signed_cert.ca.cert_pem}"

  validity_period_hours = 43800

  allowed_uses = [
    "key_encipherment",
    "digital_signature",
    "server_auth",
    "client_auth",
  ]
}

我运行 Terraform 清单。然后我从状态文件中提取生成的证书并将它们保存到文件中。

我尝试使用 openssl 验证最终证书，但出现错误：

$ openssl verify -CAfile ca-cert.pem registry.pem 
registry.pem: C = GB, ST = , L = , postalCode = , O = "Example, Ltd", OU = , CN = registry.example.com
error 20 at 0 depth lookup:unable to get local issuer certificate

任何想法是什么问题？我花了很多时间试图弄清楚这一点。

基本上我想用它来为我的测试/开发环境中的私有 Docker 注册表启用 HTTPS。

您需要添加cert_signing到tls_private_key.ca.allowed_uses：

resource "tls_self_signed_cert" "ca" {
  key_algorithm = "${tls_private_key.ca.algorithm}"
  private_key_pem = "${tls_private_key.ca.private_key_pem}"

  subject {
    common_name = "Example CA"
    organization = "Example, Ltd"
    country = "GB"
  }

  validity_period_hours = 43800
  is_ca_certificate = true

  allowed_uses = [
    "key_encipherment",
    "digital_signature",
    "server_auth",
    "client_auth",
    "cert_signing"
  ]
}
