# HANA Database Secrets Engine
|
|
|
|
HANA is one of the supported plugins for the database secrets engine. This
|
|
plugin generates database credentials dynamically based on configured roles for
|
|
the HANA 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 |
|
|
| ------------------------ | ------------------------ | ------------- | ------------ |
|
|
| `hanadb-database-plugin` | Yes (1.6+) | Yes | Yes (1.6+) |
|
|
|
|
## 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-hana-database \
|
|
plugin_name=hana-database-plugin \
|
|
connection_url="hdb://{{username}}:{{password}}@localhost:1433" \
|
|
allowed_roles="my-role" \
|
|
username="vaultuser" \
|
|
password="vaultpass"
|
|
```
|
|
|
|
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-hana-database \
|
|
creation_statements="CREATE USER {{name}} PASSWORD {{password}} VALID UNTIL '{{expiration}}';\
|
|
CALL GRANT_ACTIVATED_ROLE ( 'sap.hana.admin.roles::Monitoring', '{{name}}' );" \
|
|
default_ttl="12h" \
|
|
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 sU4zWnITaABEP-Zwy4sF
|
|
username v_vaultuser_my_role_jQbCLE6P2VtgsqPBXK0m_1602541873
|
|
```
|
|
|
