# `alicloudkms` Seal
|
|
|
|
-> **Note:** The Seal Wrap functionality is enabled by default. For this reason, the KMS service must be available throughout Vault's runtime and not just during the unseal process. Refer to the [Seal Wrap](/docs/enterprise/sealwrap) documenation for more information.
|
|
|
|
|
|
The AliCloud KMS seal configures Vault to use AliCloud KMS as the seal wrapping mechanism.
|
|
The AliCloud KMS seal is activated by one of the following:
|
|
|
|
- The presence of a `seal "alicloudkms"` block in Vault's configuration file.
|
|
- The presence of the environment variable `VAULT_SEAL_TYPE` set to `alicloudkms`. If
|
|
enabling via environment variable, all other required values specific to AliCloud
|
|
KMS (i.e. `VAULT_ALICLOUDKMS_SEAL_KEY_ID`) must be also supplied, as well as all
|
|
other AliCloud-related environment variables that lends to successful
|
|
authentication.
|
|
|
|
## `alicloudkms` Example
|
|
|
|
This example shows configuring AliCloud KMS seal through the Vault configuration file
|
|
by providing all the required values:
|
|
|
|
```hcl
|
|
seal "alicloudkms" {
|
|
region = "us-east-1"
|
|
access_key = "0wNEpMMlzy7szvai"
|
|
secret_key = "PupkTg8jdmau1cXxYacgE736PJj4cA"
|
|
kms_key_id = "08c33a6f-4e0a-4a1b-a3fa-7ddfa1d4fb73"
|
|
}
|
|
```
|
|
|
|
## `alicloudkms` Parameters
|
|
|
|
These parameters apply to the `seal` stanza in the Vault configuration file:
|
|
|
|
- `region` `(string: <required> "us-east-1")`: The AliCloud region where the encryption key
|
|
lives. May also be specified by the `ALICLOUD_REGION`
|
|
environment variable.
|
|
|
|
- `domain` `(string: "kms.us-east-1.aliyuncs.com")`: If set, overrides the endpoint
|
|
AliCloud would normally use for KMS for a particular region. May also be specified
|
|
by the `ALICLOUD_DOMAIN` environment variable.
|
|
|
|
- `access_key` `(string: <required>)`: The AliCloud access key ID to use. May also be
|
|
specified by the `ALICLOUD_ACCESS_KEY` environment variable or as part of the
|
|
AliCloud profile from the AliCloud CLI or instance profile.
|
|
|
|
- `secret_key` `(string: <required>)`: The AliCloud secret access key to use. May
|
|
also be specified by the `ALICLOUD_SECRET_KEY` environment variable or as
|
|
part of the AliCloud profile from the AliCloud CLI or instance profile.
|
|
|
|
- `kms_key_id` `(string: <required>)`: The AliCloud KMS key ID to use for encryption
|
|
and decryption. May also be specified by the `VAULT_ALICLOUDKMS_SEAL_KEY_ID`
|
|
environment variable.
|
|
|
|
- `disabled` `(string: "")`: Set this to `true` if Vault is migrating from an auto seal configuration. Otherwise, set to `false`.
|
|
|
|
Refer to the [Seal Migration](/docs/concepts/seal#seal-migration) documentation for more information about the seal migration process.
|
|
|
|
## Authentication
|
|
|
|
Authentication-related values must be provided, either as environment
|
|
variables or as configuration parameters.
|
|
|
|
~> **Note:** Although the configuration file allows you to pass in
|
|
`ALICLOUD_ACCESS_KEY` and `ALICLOUD_SECRET_KEY` as part of the seal's parameters, it
|
|
is _strongly_ recommended to set these values via environment variables.
|
|
|
|
```text
|
|
AliCloud authentication values:
|
|
|
|
* `ALICLOUD_REGION`
|
|
* `ALICLOUD_ACCESS_KEY`
|
|
* `ALICLOUD_SECRET_KEY`
|
|
```
|
|
|
|
Note: The client uses the official AliCloud SDK and will use environment credentials,
|
|
the specified credentials, or RAM role credentials in that order.
|
|
|
|
## `alicloudkms` Environment Variables
|
|
|
|
Alternatively, the AliCloud KMS seal can be activated by providing the following
|
|
environment variables:
|
|
|
|
```text
|
|
Vault Seal specific values:
|
|
|
|
* `VAULT_SEAL_TYPE`
|
|
* `VAULT_ALICLOUDKMS_SEAL_KEY_ID`
|
|
```
