This plugin generates database credentials dynamically based on configured roles for the Cassandra database. See the [database secrets engine](/docs/secrets/databases/index.html) docs for more information about setting up the database secrets engine. ## Setup 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=cassandra \ password=cassandra \ 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 8cab931c-d62e-a73d-60d3-5ee85139cd66 username v-root-e2978cd0- ``` ## API The full list of configurable options can be seen in the [Cassandra database plugin API](/api/secret/databases/cassandra.html) page.
