# Google Cloud Secrets Engine (API)
This is the API documentation for the Vault Google Cloud Platform (GCP)
secrets engine. For general information about the usage and operation of
the GCP secrets engine, please see [these docs](/docs/secrets/gcp/index.html).
This documentation assumes the GCP secrets engine is enabled at the `/gcp` path
in Vault. Since it is possible to mount secrets engines at any path, please
update your API calls accordingly.
## Write Config
| Method | Path | Produces |
| :------- | :------------------------| :------------------------ |
| `POST` | `/gcp/config` | `204 (empty body)` |
This endpoint configures shared information for the secrets engine.
### Parameters
- `credentials` (`string:""`) - JSON credentials (either file contents or '@path/to/file')
See docs for [alternative ways](/docs/secrets/gcp/index.html#passing-credentials-to-vault)
to pass in to this parameter, as well as the
[required permissions](/docs/secrets/gcp/index.html#required-permissions).
- `ttl` (`int: 0 || string:"0s"`) Specifies default config TTL for long-lived credentials
(i.e. service account keys). Accepts integer number of seconds or Go duration format string.
- `max_ttl` (`int: 0 || string:"0s"`) Specifies the maximum config TTL for long-lived credentials
(i.e. service account keys). Accepts integer number of seconds or Go duration format string.**
### Sample Payload
```json
{
"credentials": "<JSON string>",
"ttl": 3600,
"max_ttl": 14400
}
```
### Sample Request
```
$ curl \
--header "X-Vault-Token: ..." \
--request POST \
--data @payload.json \
https://127.0.0.1:8200/v1/gcp/config
```
## Read Config
| Method | Path | Produces |

```
## Create/Update Roleset
| Method | Path | Produces |
| :------- | :------------------------| :------------------------ |
| `POST` | `/gcp/roleset/:name` | `204 (empty body)` |
This method allows you to create a roleset or update an existing roleset. See [roleset docs](/docs/secrets/gcp/index.html#rolesets) for the GCP secrets backend
to learn more about what happens when you create or update a roleset.
**If you update a roleset's bindings, this will effectively revoke any secrets
generated under this roleset.**
### Parameters
- `name` (`string: <required>`): Required. Name of the role. Cannot be updated.
- `secret_type` (`string: "access_token"`): Type of secret generated for this role set. Accepted values: `access_token`, `service_account_key`. Cannot be updated.
- `project` (`string: <required>`): Name of the GCP project that this roleset's service account will belong to. Cannot be updated.
- `bindings` (`string: <required>`): Bindings configuration string (expects HCL or JSON format in raw or base64-encoded string)
- `token_scopes` (`array: []`): List of OAuth scopes to assign to `access_token` secrets generated under this role set (`access_token` role sets only)
### Sample Payload
```json
{
"secret_type": "access_token",
"project": "mygcpproject",
"bindings": "...",
"token_scopes": [
"https://www.googleapis.com/auth/cloud-platform",
"https://www.googleapis.com/auth/bigquery"
]
}
```
#### Sample Bindings:
See [bindings format docs](/docs/secrets/gcp/index.html#roleset-bindings) for more information.
```hcl
resource "//cloudresourcemanager.googleapis.com/projects/mygcpproject" {
roles = [
"roles/viewer"
],
}
resource "https://selflink/to/my/resource" {
roles = [
"project/mygcpproject/roles/projcustomrole",
"organizations/myorg/roles/orgcustomrole"
],
}
```
### Sample Request
```
$ curl \
--header "X-Vault-Token: ..." \
--request POST \
--data @payload.json \
https://127.0.0.1:8200/v1/gcp/roleset/my-token-roleset
```
## Rotate Roleset Account
| Method | Path | Produces |
| :------- | :--------------------------------| :--------------------- |
| `POST` | `/gcp/roleset/:name/rotate` | `204 (empty body)`` |
This will rotate the service account this roleset uses to generate secrets.
(this also replaces the key `access_token` roleset). This can be used to invalidate
old secrets generated by the roleset or fix issues if a roleset's service account
(and/or keys) was changed outside of Vault (i.e. through GCP APIs/cloud console).
### Sample Request
```
$ curl \
--header "X-Vault-Token: ..." \
--request POST \
https://127.0.0.1:8200/v1/consul/gcp/roleset/my-token-roleset/rotate
```
## Rotate Roleset Account Key (`access_token` Roleset Only)
| Method | Path | Produces |
| :------- | :--------------------------------| :--------------------- |
| `POST` | `/gcp/roleset/:name/rotate-key` | `204 (empty body)`` |
This will rotate the service account key this roleset uses to generate
access tokens. This does not recreate the roleset service account.
### Sample Request
```
$ curl \
--header "X-Vault-Token: ..." \
--request POST \
https://127.0.0.1:8200/v1/consul/gcp/roleset/my-token-roleset/rotate-key
```
## Read Roleset
| Method | Path | Produces |

--request GET \
https://127.0.0.1:8200/v1/consul/gcp/roleset/my-token-roleset
```
### Sample Response
```json
{
"data": {
"secret_type": "access_token",
"service_account_email": "vault-myroleset-XXXXXXXXXX@myproject.gserviceaccounts.com",

## Generate Secret (IAM Service Account Creds): OAuth2 Access Token
| Method | Path | Produces |
| :---------------- | :----------------------------- | :------------------------ |
| `GET` | `POST` | `/gcp/token/:roleset` | `200 application/json` |
Generates an OAuth2 token with the scopes defined on the roleset. This OAuth access token can
be used in GCP API calls, e.g. `curl -H "Authorization: Bearer $TOKEN" ...`
Tokens are non-revocable and non-renewable and have a static TTL of an hour. The TTL configured
for the backend (either through the default system TTLs or through the `config/` endpoint)
do not apply.
### Parameters
- `roleset` (`string:<required>`): Name of an roleset with secret type `access_token` to generate access_token under.
### Sample Request
```sh
$ curl \
--header "X-Vault-Token: ..." \
--request GET \
https://127.0.0.1:8200/v1/consul/gcp/roleset/my-token-roleset
```
### Sample Response
```json
{
"request_id":"<uuid>",
"data": {
"token":"ya29.c.Elp5Be3ga87...",
"expires_at_seconds": 1537400046,
"token_ttl": 3599
},
"wrap_info": null,
"warnings": null,
"auth": null
}
```
## Generate Secret (IAM Service Account Creds): Service Account Key
| Method | Path | Produces |
| :---------------- | :----------------------------- | :------------------------ |
| `GET` | `POST` | `/gcp/key/:roleset` | `200 application/json` |
If using `GET` ('read'), the optional parameters will be set to their defaults. Use `POST` if you
want to specify different values for these params.
These keys are renewable and have TTL/max TTL as defined by either the backend config
or the system default if config was not defined.
### Parameters
- `roleset` (`string:<required>`): Name of an roleset with secret type `service_account_key` to generate key under.
- `key_algorithm` (`string:"KEY_ALG_RSA_2048"`): Key algorithm used to generate key. Defaults to 2k RSA key
You probably should not choose other values (i.e. 1k), but accepted values are
`enum(`[`ServiceAccountKeyAlgorithm`](https://cloud.google.com/iam/reference/rest/v1/projects.serviceAccounts.keys#ServiceAccountKeyAlgorithm)`)`
- `key_type` (`string:"TYPE_GOOGLE_CREDENTIALS_FILE`): Private key type to generate. Defaults to JSON credentials file.
Accepted values are `enum(`[`ServiceAccountPrivateKeyType`](https://cloud.google.com/iam/reference/rest/v1/projects.serviceAccounts.keys#ServiceAccountPrivateKeyType)`)`
### Sample Payload
```json
{
"key_algorithm": "TYPE_GOOGLE_CREDENTIALS_FILE",
"key_type": "KEY_ALG_RSA_2048"
}
```
### Sample Request
```sh
$ curl \

--header "X-Vault-Token: ..." \
--request POST \
--data @payload.json \
https://127.0.0.1:8200/v1/gcp/roleset/my-token-roleset
```
### Sample Response
```json
{
"request_id":"<uuid>",
"lease_id":"gcp/key/my-key-roleset/<uuid>",
"renewable":true,
"lease_duration":3600,
"data": {
"private_key_data":"<base64-encoded private key data>",

## Revoking/Renewing Secrets
See docs on how to [renew](/api/system/leases.html#renew-lease) and [revoke](/api/system/leases.html#revoke-lease) leases.
Note this only applies to service account keys.
