Database

Note

Every method under the Database class includes a mount_point parameter that can be used to address the Database secret engine under a custom mount path. E.g., If enabling the Database secret engine using Vault’s CLI commands via vault secrets enable -path=my-database database, the mount_point parameter in hvac.api.secrets_engines.Database() methods would be set to my-database.

Enable Database Secrets Engine

import hvac
client = hvac.Client()

client.sys.enable.secrets_engine(
    backend_type='database',
    path='my-database'
)

Note

Example code below are for configuring and connecting to Postgres. See the official developer docs for a list of supported database plugins and detailed configuration requirements.

Configuration

hvac.api.secrets_engines.Database.configure()

Configures the database engine:

import hvac
client = hvac.Client()

client.secrets.database.configure(
    name='db-connection-name',
    plugin_name='postgresql-database-plugin',
    allowed_roles='role-name',
    connection_url=f'postgresql://{{{{username}}}}:{{{{password}}}}@postgres:5432/postgres?sslmode=disable',
    username='db-username',
    password='db-password',
)

Note

The database needs to be created and available to connect before you can configure the database secrets engine using the above configure method.

Read Configuration

hvac.api.secrets_engines.Database.read_connection()

Returns the configuration settings for a connection mounted under a path of my-database:

import hvac
client = hvac.Client()

connection_config = client.secrets.database.read_connection(
    name='db-connection-name',
    mount_point='my-database'
)

List Connections

hvac.api.secrets_engines.Database.list_connections()

Returns a list of available connections:

import hvac
client = hvac.Client()

connections = client.secrets.database.list_connections(
    mount_point='my-database'
)

Delete Connection

hvac.api.secrets_engines.Database.delete_connection()

Deletes a connection:

import hvac
client = hvac.Client()

client.secrets.database.delete_connection(
    name='db-connection-name',
    mount_point='my-database'
)

Reset Connection

hvac.api.secrets_engines.Database.reset_connection()

Closes a connection and its underlying plugin and restarts it with the configuration stored:

import hvac
client = hvac.Client()

client.secrets.database.reset_connection(
    name='db-connection-name',
    mount_point='my-database'
)

Create Role

hvac.api.secrets_engines.Database.create_role()

Creates or updates a role definition:

import hvac
client = hvac.Client()

# SQL to create a new user with read only role to public schema
    creation_statements = [
        "CREATE ROLE \"{{name}}\" WITH LOGIN PASSWORD '{{password}}' VALID UNTIL '{{expiration}}';",
        "GRANT SELECT ON ALL TABLES IN SCHEMA public TO \"{{name}}\";"
    ]

# Create a new role for the PostgreSQL connection
    client.secrets.database.create_role(
        name='role-name',
        db_name='db-connection-name',
        creation_statements=creation_statements,
        default_ttl='1h',
        max_ttl='24h',
        mount_point='my-database'
    )

Read A Role

hvac.api.secrets_engines.Database.read_role()

Creates or updates a role definition:

import hvac
client = hvac.Client()

role = client.secrets.database.read_role(
    name='role-name',
    mount_point='my-database'
)

List All The Roles

hvac.api.secrets_engines.Database.list_roles()

Returns a list of available roles:

import hvac
client = hvac.Client()

roles = client.secrets.database.list_roles(
    mount_point='my-database'
)

Delete A Role

hvac.api.secrets_engines.Database.delete_role()

Deletes a role definition:

import hvac
client = hvac.Client()

client.secrets.database.delete_role(
    name='role-name',
    mount_point='my-database'
)

Rotate Root Credentials

hvac.api.secrets_engines.Database.rotate_root_credentials()

Rotates the root credentials stored for the database connection. This user must have permissions to update its own password.

import hvac
client = hvac.Client()

client.secrets.database.rotate_root_credentials(
    name='db-connection-name',
    mount_point='my-database'
)

Generate Credentials

hvac.api.secrets_engines.Database.generate_credentials()

Generates a new set of dynamic credentials based on the named role:

import hvac
client = hvac.Client()

credentials = client.secrets.database.generate_credentials(
    name='role-name',
    mount_point='my-database'
)

Get Static Credentials

hvac.api.secrets_engines.Database.get_static_credentials()

Returns the current credentials based on the named static role:

import hvac
client = hvac.Client()

credentials = client.secrets.database.get_static_credentials(
    name='role-name',
    mount_point='my-database'
)
