Oracle Database Secrets Engine

Oracle is one of the supported plugins for the database secrets engine. This plugin generates database credentials dynamically based on configured roles for the Oracle database.

The Oracle database plugin is not bundled in the core Vault code tree and can be found at its own git repository here: hashicorp/vault-plugin-database-oracle

See the Database Backend docs for more information about setting up the Database Backend.

Setup

The Oracle Database Plugin does not live in the core Vault code tree and can be found at its own git repository here: hashicorp/vault-plugin-database-oracle

Before running the plugin you will need to have the the Oracle Instant Client library installed. These can be downloaded from Oracle. The libraries will need to be placed in the default library search path or somewhere defined in the LD_LIBRARY_PATH environment variable.

1. Enable the database secrets engine if it is not already enabled:

   $ 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.

2. Download and register the plugin:

   $ vault write sys/plugins/catalog/oracle-database-plugin \
       sha_256="..." \
       command=oracle-database-plugin
   

3. Configure Vault with the proper plugin and connection information:

   $ vault write database/config/my-oracle-database \
       plugin_name=oracle-database-plugin \
       connection_url="system/Oracle@localhost:1521/OraDoc.localhost" \
       allowed_roles="my-role"
   

4. Configure a role that maps a name in Vault to an SQL statement to execute to create the database credential:

   $ vault write database/roles/my-role \
       db_name=my-oracle-database \
       creation_statements="CREATE USER {{name}} IDENTIFIED BY {{password}}; GRANT CONNECT TO {{name}}; GRANT CREATE SESSION TO {{name}};" \
       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:

   $ 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-
