# Cassandra Database Secrets Engine
|
|
|
|
Cassandra is one of the supported plugins for the database secrets engine. This
|
|
plugin generates database credentials dynamically based on configured roles for
|
|
the Cassandra database.
|
|
|
|
See the [database secrets engine](/docs/secrets/databases) docs for
|
|
more information about setting up the database secrets engine.
|
|
|
|
## Capabilities
|
|
|
|
| Plugin Name | Root Credential Rotation | Dynamic Roles | Static Roles | Username Customization |
|
|
| --------------------------- | ------------------------ | ------------- | ------------ | ---------------------- |
|
|
| `cassandra-database-plugin` | Yes | Yes | Yes (1.6+) | Yes (1.7+) |
|
|
|
|
## Setup
|
|
|
|
1. Vault will need a Cassandra user with the following permissions:
|
|
```text
|
|
GRANT CREATE ON ALL ROLES to '<YOUR USER>';
|
|
GRANT ALTER ON ALL ROLES to '<YOUR USER>';
|
|
GRANT DROP ON ALL ROLES to '<YOUR USER>';
|
|
GRANT AUTHORIZE ON ALL ROLES to '<YOUR USER>';
|
|
```
|
|
|
|
1. Enable the database secrets engine if it is not already enabled:
|
|
|
|
```text
|
|
$ vault secrets enable database
|
|
Success! Enabled the database secrets engine at: database/
|
|
```
|
|
|
|
By default, the secrets engine will enable at the name of the engine. To
|
|
enable the secrets engine at a different path, use the `-path` argument.
|
|
|
|
1. Configure Vault with the proper plugin and connection information:
|
|
|
|
```text
|
|
$ vault write database/config/my-cassandra-database \
|
|
plugin_name="cassandra-database-plugin" \
|
|
hosts=127.0.0.1 \
|
|
protocol_version=4 \
|
|
username=vaultuser \
|
|
password=vaultpass \
|
|
allowed_roles=my-role
|
|
```
|
|
|
|
1. Configure a role that maps a name in Vault to an SQL statement to execute to
|
|
create the database credential:
|
|
|
|
```text
|
|
$ vault write database/roles/my-role \
|
|
db_name=my-cassandra-database \
|
|
creation_statements="CREATE USER '{{username}}' WITH PASSWORD '{{password}}' NOSUPERUSER; \
|
|
GRANT SELECT ON ALL KEYSPACES TO {{username}};" \
|
|
default_ttl="1h" \
|
|
max_ttl="24h"
|
|
Success! Data written to: database/roles/my-role
|
|
```
|
|
|
|
## Usage
|
|
|
|
After the secrets engine is configured and a user/machine has a Vault token with
|
|
the proper permission, it can generate credentials.
|
|
|
|
1. Generate a new credential by reading from the `/creds` endpoint with the name
|
|
of the role:
|
|
|
|
```text
|
|
$ vault read database/creds/my-role
|
|
Key Value
|
|
--- -----
|
|
lease_id database/creds/my-role/2f6a614c-4aa2-7b19-24b9-ad944a8d4de6
|
|
lease_duration 1h
|
|
lease_renewable true
|
|
password 7iO-FxlVCdj8szsgGgsL
|
|
username v_vaultuser_my_role_6zjahr4mjn5c9prgucy1_1602541475
|
|
```
|
