Database secrets engine (API)
This is the API documentation for the OpenBao Database secrets engine. For general information about the usage and operation of the database secrets engine, please see the OpenBao database secrets engine documentation.
This documentation assumes the database secrets engine is enabled at the
/database
path in OpenBao. Since it is possible to enable secrets engines at any
location, please update your API calls accordingly.
Configure connection
This endpoint configures the connection string used to communicate with the desired database. In addition to the parameters listed here, each Database plugin has additional, database plugin specific, parameters for this endpoint. Please read the HTTP API for the plugin you'd wish to configure to see the full list of additional parameters.
This endpoint distinguishes between create
and update
ACL capabilities.
Method | Path |
---|---|
POST | /database/config/:name |
Parameters
-
name
(string: <required>)
– Specifies the name for this database connection. This is specified as part of the URL. -
plugin_name
(string: <required>)
- Specifies the name of the plugin to use for this connection. -
plugin_version
(string: "")
- Specifies the semantic version of the plugin to use for this connection. -
verify_connection
(bool: true)
– Specifies if the connection is verified during initial configuration. Defaults to true. -
allowed_roles
(list: [])
- List of the roles allowed to use this connection. Defaults to empty (no roles), if contains a*
any role can use this connection. -
root_rotation_statements
(list: [])
- Specifies the database statements to be executed to rotate the root user's credentials. See the plugin's API page for more information on support and formatting for this parameter. -
password_policy
(string: "")
- The name of the password policy to use when generating passwords for this database. If not specified, this will use a default policy defined as: 20 characters with at least 1 uppercase, 1 lowercase, 1 number, and 1 dash character.
We highly recommended that you use an OpenBao-specific user rather than the admin user in your database when configuring the plugin. This user will be used to create/update/delete users within the database so it will need to have the appropriate permissions to do so. If the plugin supports rotating the root credentials, we highly recommended you perform that action after configuring the plugin. This will change the password of the user configured in this step. The new password will not be viewable by users.
Common fields
There are several common fields that you will see across many of the database plugins. Please reference the individual plugin documentation for details on whether these fields are supported and any additional details about them.
-
connection_url
(string)
- Specifies the connection string used to connect to the database. Some plugins useurl
rather thanconnection_url
. This allows for simple templating of the username and password of the root user. Typically, this is done by including a{{username}}
,{{name}}
, and/or{{password}}
field within the string. These fields are typically be replaced with the values in theusername
andpassword
fields. -
username
(string)
- Specifies the name of the user to use as the "root" user when connecting to the database. This "root" user is used to create/update/delete users managed by these plugins, so you will need to ensure that this user has permissions to manipulate users appropriate to the database. This is typically used in theconnection_url
field via the templating directive{{username}}
or{{name}}
. -
password
(string)
- Specifies the password to use when connecting with theusername
. This value will not be returned by OpenBao when performing a read upon the configuration. This is typically used in theconnection_url
field via the templating directive{{password}}
. -
disable_escaping
(boolean: false)
- Determines whether special characters in the username and password fields will be escaped. Useful for alternate connection string formats like ADO. More information regarding this parameter can be found on the databases secrets engine docs. Defaults tofalse
.
