I am looking to copy a single certificate from Test1-KV to New-KV with teh following code, but I am receiving the following error:

azurerm_key_vault_certificate.new-cert: Creating...

Error: keyvault.BaseClient#CreateCertificate: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="BadParameter" Message="Property policy has invalid value\r\n"

on resources.tf line 91, in resource "azurerm_key_vault_certificate" "new-cert": 91: resource "azurerm_key_vault_certificate" "new-cert" {

Code:

data "azurerm_key_vault" "existing" {
  name                = "Test1-KV"
  resource_group_name = "Test1-RG"
  
}

data "azurerm_key_vault_certificate" "new-cert" {
  name          = "new-cert"
  key_vault_id  = data.azurerm_key_vault.existing.id
}

resource "azurerm_key_vault_certificate" "new-cert" {
  name         = "new-cert"
  key_vault_id = azurerm_key_vault.new-kv.id

Not sure what your error is specifically, but your code is not functional for what you are trying to do. I am providing an example of the first run to create a cert, and the second run to import it into a new kv. The trick is to source the secret generated by the cert to import it. I validate the process worked via the thumbprints.

This is the first main.tf to generate initial kv and cert

provider "azurerm" {
  version = "~>2.23.0"
  features {}
}

data "azurerm_client_config" "current" {
}

resource "azurerm_resource_group" "example" {
  name     = "key-vault-certificate-example"
  location = "East US"
}

output "certificate_thumbprint" {
  value = azurerm_key_vault_certificate.example.thumbprint
}

resource "azurerm_key_vault" "example" {
  name                = "pearceckvcertexample"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  tenant_id           = data.azurerm_client_config.current.tenant_id

  sku_name = "standard"

  access_policy {
    tenant_id = data.azurerm_client_config.current.tenant_id
    object_id = data.azurerm_client_config.current.object_id

    certificate_permissions = [
      "create",
      "delete",
      "deleteissuers",
      "get",
      "getissuers",
      "import",
      "list",
      "listissuers",
      "managecontacts",
      "manageissuers",
      "setissuers",
      "update",
    ]

    key_permissions = [
      "backup",
      "create",
      "decrypt",
      "delete",
      "encrypt",
      "get",

      "sign",
      "unwrapKey",
      "update",
      "verify",
      "wrapKey",
    ]

    secret_permissions = [
      "backup",
      "delete",
      "get",
      "list",
      "purge",
      "recover",
      "restore",
      "set",
    ]
  }

  tags = {
    environment = "Production"
  }
}

resource "azurerm_key_vault_certificate" "example" {
  name         = "generated-cert"
  key_vault_id = azurerm_key_vault.example.id

  certificate_policy {
    issuer_parameters {
      name = "Self"
    }

    key_properties {
      exportable = true
      key_size   = 2048
      key_type   = "RSA"
      reuse_key  = true
    }

    lifetime_action {
      action {
        action_type = "AutoRenew"
      }

      trigger {
        days_before_expiry = 30
      }
    }

    secret_properties {
      content_type = "application/x-pkcs12"
    }

    x509_certificate_properties {
      # Server Authentication = 1.3.6.1.5.5.7.3.1
      # Client Authentication = 1.3.6.1.5.5.7.3.2
      extended_key_usage = ["1.3.6.1.5.5.7.3.1"]

      key_usage = [
        "cRLSign",
        "dataEncipherment",
        "digitalSignature",
        "keyAgreement",
        "keyCertSign",
        "keyEncipherment",
      ]

      subject_alternative_names {
        dns_names = ["internal.contoso.com", "domain.hello.world"]
      }

      subject            = "CN=hello-world"
      validity_in_months = 12
    }
  }
}

THis is the second main.tf (different state), to generate a second kv and import the cert from the secret in the original vault.

provider "azurerm" {
  version = "~>2.23.0"
  features {}
}

data "azurerm_client_config" "current" {
}

data "azurerm_key_vault" "example" {
  name                = "pearceckvcertexample"
  resource_group_name = "key-vault-certificate-example"
}

// It stores the actual cert as a secret
data "azurerm_key_vault_secret" "example" {
  name         = "generated-cert"
  key_vault_id = data.azurerm_key_vault.example.id
}

data "azurerm_key_vault_certificate" "example" {
  name         = "generated-cert"
  key_vault_id = data.azurerm_key_vault.example.id
}

output "certificate_thumbprint" {
  value = data.azurerm_key_vault_certificate.example.thumbprint
}

output "certificate_thumbprint2" {
  value = azurerm_key_vault_certificate.example.thumbprint
}

resource "azurerm_resource_group" "example" {
  name     = "key-vault-certificate-example2"
  location = "East US"
}

resource "azurerm_key_vault" "example" {
  name                = "pearceckvcertexample2"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  tenant_id           = data.azurerm_client_config.current.tenant_id

  sku_name = "standard"

  access_policy {
    tenant_id = data.azurerm_client_config.current.tenant_id
    object_id = data.azurerm_client_config.current.object_id

      # Server Authentication = 1.3.6.1.5.5.7.3.1
      # Client Authentication = 1.3.6.1.5.5.7.3.2
      extended_key_usage = ["1.3.6.1.5.5.7.3.1"]

Output from the run:

the issue is resolved by add below code

data "azurerm_key_vault" "New-KV" {
  name                = "New-KV"
  resource_group_name = "New-RG"
}

data "azurerm_key_vault_secret" "Test1-KV" {
  name         = "Cert"
  key_vault_id = data.azurerm_key_vault.existing.id
}

data "azurerm_key_vault_certificate" "Cert" {
  name         = "Cert"
  key_vault_id = data.azurerm_key_vault.existing.id
}

resource "azurerm_key_vault_certificate" "Cert" {
  name         = "Cert"
  key_vault_id = data.azurerm_key_vault.New-KV.id


 certificate {
    contents = data.azurerm_key_vault_secret.Test1-KV.value
  }

certificate_policy {
    issuer_parameters {
      name = "self" (instead using original issuer use self)
    }

    key_properties {
      exportable = true
      key_size   = 2048
      key_type   = "RSA"
      reuse_key  = true
    }

    secret_properties {
      content_type = "application/x-pkcs12"
    }


  }
