Azure secrets engine (API)

This is the API documentation for the Vault Azure secrets engine. For general information about the usage and operation of the Azure secrets engine, please see the main Azure secrets documentation.

This documentation assumes the Azure secrets engine is enabled at the /azure path in Vault. Since it is possible to mount secrets engines at any path, please update your API calls accordingly.

Configure access

Configures the credentials required for the plugin to perform API calls to Azure. These credentials will be used to query roles and create/delete service principals. Environment variables will override any parameters set in the config.

Method	Path
POST	/azure/config

• subscription_id (string: <required>) - The subscription id for the Azure Active Directory. This value can also be provided with the AZURE_SUBSCRIPTION_ID environment variable.

• tenant_id (string: <required>) - The tenant id for the Azure Active Directory. This value can also be provided with the AZURE_TENANT_ID environment variable.

• client_id (string:"") - The OAuth2 client id to connect to Azure. This value can also be provided with the AZURE_CLIENT_ID environment variable. See authentication for more details.

• client_secret (string:"") - The OAuth2 client secret to connect to Azure. This value can also be provided with the AZURE_CLIENT_SECRET environment variable. See authentication for more details.

• environment (string:"") - The Azure environment. This value can also be provided with the AZURE_ENVIRONMENT environment variable. If not specified, Vault will use Azure Public Cloud.

• password_policy (string: "") - Specifies a password policy to use when creating dynamic credentials. Defaults to generating an alphanumeric password if not set.

• root_password_ttl (string: 182d) - Specifies how long the root password is valid for in Azure when rotate-root generates a new client secret. Uses duration format strings.

Sample payload

{
  "subscription_id": "94ca80...",
  "tenant_id": "d0ac7e...",
  "client_id": "e607c4...",
  "client_secret": "9a6346...",
  "environment": "AzureGermanCloud",
  "password_policy": "azure_policy",
  "root_password_ttl": "48d"
}

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    https://127.0.0.1:8200/v1/azure/config

Read config

Return the stored configuration, omitting client_secret.

Method	Path
GET	/azure/config

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request GET \
    https://127.0.0.1:8200/v1/azure/config

Sample response

{
  "data": {
    "subscription_id": "94ca80...",
    "tenant_id": "d0ac7e...",
    "client_id": "e607c4...",
    "environment": "AzureGermanCloud"
  },
  ...
}

Delete config

Deletes the stored Azure configuration and credentials.

Method	Path
DELETE	/azure/config

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request DELETE \
    https://127.0.0.1:8200/v1/azure/config

Rotate root

This endpoint generates a new client secret for the root account defined in the config. The value generated will only be known by Vault.

Due to the eventual consistency of Microsoft Azure client secret APIs, the plugin may briefly stop authenticating to Azure as the password propagates through their datacenters.

Method	Path
POST	/azure/rotate-root

Parameters

There are no parameters to this operation.

Sample request

$ curl \
  --header "X-Vault-Token: ..." \
  --request POST \
  http://127.0.0.1:8200/v1/azure/rotate-root

Create/Update role

Create or update a Vault role. Either application_object_id or azure_roles must be provided, and these resources must exist for this call to succeed. See the Azure secrets roles docs for more information about roles.

Method	Path
POST	/azure/roles/:name

Parameters

• azure_roles (string: "") - List of Azure roles to be assigned to the generated service principal. The array must be in JSON format, properly escaped as a string. See roles docs for details on role definition.

• azure_groups (string: "") - List of Azure groups that the generated service principal will be assigned to. The array must be in JSON format, properly escaped as a string. See groups docs for more details.

• application_object_id (string: "") - Application Object ID for an existing service principal that will be used instead of creating dynamic service principals. If present, azure_roles will be ignored. See roles docs for details on role definition.

• persist_app (bool: "false") – If set to true, persists the created service principal and application for the lifetime of the role. Useful for when the Service Principal needs to maintain ownership of objects it creates

• ttl (string: "") – Specifies the default TTL for service principals generated using this role. Accepts time suffixed strings ("1h") or an integer number of seconds. Defaults to the system/engine default TTL time.

• max_ttl (string: "") – Specifies the maximum TTL for service principals generated using this role. Accepts time suffixed strings ("1h") or an integer number of seconds. Defaults to the system/engine max TTL time.

• permanently_delete (bool: false) - Specifies whether to permanently delete Applications and Service Principals that are dynamically created by Vault. If application_object_id is present, permanently_delete must be false.

  "azure_roles": "[
    {
