AZU022 - Key vault Secret should have a content type set

Explanation

Content Type is an optional Key Vault Secret behavior and is not enabled by default.

Clients may specify the content type of a secret to assist in interpreting the secret data when it’s retrieved. The maximum length of this field is 255 characters. There are no pre-defined values. The suggested usage is as a hint for interpreting the secret data.

Insecure Example

The following example will fail the AZU022 check.

resource "azurerm_key_vault_secret" "bad_example" {
  name         = "secret-sauce"
  value        = "szechuan"
  key_vault_id = azurerm_key_vault.example.id
}

Secure Example

The following example will pass the AZU022 check.

resource "azurerm_key_vault_secret" "good_example" {
  name         = "secret-sauce"
  value        = "szechuan"
  key_vault_id = azurerm_key_vault.example.id
  content_type = "password"
}
