When we "nest" like this, it's important to use a common suffix, "Database Secret Backend" in this case, so that the SEO minions can properly group search results for end users.

# Cassandra Database Plugin
|
|
|
|
Name: `cassandra-database-plugin`
|
|
|
|
The Cassandra Database Plugin is one of the supported plugins for the Database
|
|
backend. This plugin generates database credentials dynamically based on
|
|
configured roles for the Cassandra database.
|
|
|
|
See the [Database Backend](/docs/secrets/databases/index.html) docs for more
|
|
information about setting up the Database Backend.
|
|
|
|
## Quick Start
|
|
|
|
After the Database Backend is mounted you can configure a cassandra connection
|
|
by specifying this plugin as the `"plugin_name"` argument. Here is an example
|
|
cassandra configuration:
|
|
|
|
```
|
|
$ vault write database/config/cassandra \
|
|
plugin_name=cassandra-database-plugin \
|
|
allowed_roles="readonly" \
|
|
hosts=localhost \
|
|
username=cassandra \
|
|
password=cassandra
|
|
|
|
The following warnings were returned from the Vault server:
|
|
* Read access to this endpoint should be controlled via ACLs as it will return the connection details as is, including passwords, if any.
|
|
```
|
|
|
|
Once the cassandra connection is configured we can add a role:
|
|
|
|
```
|
|
$ vault write database/roles/readonly \
|
|
db_name=cassandra \
|
|
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/readonly
|
|
```
|
|
|
|
This role can be used to retrieve a new set of credentials by querying the
|
|
"database/creds/readonly" endpoint.
|
|
|
|
