# Influxdb Database Plugin HTTP API
|
||
|
||
The Influxdb database plugin is one of the supported plugins for the database
|
||
secrets engine. This plugin generates database credentials dynamically based on
|
||
configured roles for the Influxdb database.
|
||
|
||
## Configure Connection
|
||
|
||
In addition to the parameters defined by the [Database
|
||
Secrets Engine](/api/secret/databases/index.html#configure-connection), this plugin
|
||
has a number of parameters to further configure a connection.
|
||
|
||
| Method | Path |
|
||
| :--------------------------- | :--------------------- |
|
||
| `POST` | `/database/config/:name` |
|
||
|
||
### Parameters
|
||
- `host` `(string: <required>)` – Specifies a Influxdb
|
||
host to connect to.
|
||
|
||
- `port` `(int: 8086)` – Specifies the default port to use if none is provided
|
||
as part of the host URI. Defaults to Influxdb's default transport port, 8086.
|
||
|
||
- `username` `(string: <required>)` – Specifies the username to use for
|
||
superuser access.
|
||
|
||
- `password` `(string: <required>)` – Specifies the password corresponding to
|
||
the given username.
|
||
|
||
- `tls` `(bool: true)` – Specifies whether to use TLS when connecting to
|
||
Influxdb.
|
||
|
||
- `insecure_tls` `(bool: false)` – Specifies whether to skip verification of the
|
||
server certificate when using TLS.
|
||
|
||
- `pem_bundle` `(string: "")` – Specifies concatenated PEM blocks containing a
|
||
certificate and private key; a certificate, private key, and issuing CA
|
||
certificate; or just a CA certificate.
|
||
|
||
- `pem_json` `(string: "")` – Specifies JSON containing a certificate and
|
||
private key; a certificate, private key, and issuing CA certificate; or just a
|
||
CA certificate. For convenience format is the same as the output of the
|
||
`issue` command from the `pki` secrets engine; see
|
||
[the pki documentation](/docs/secrets/pki/index.html).
|
||
|
||
- `connect_timeout` `(string: "5s")` – Specifies the connection timeout to use.
|
||
|
||
TLS works as follows:
|
||
|
||
- If `tls` is set to true, the connection will use TLS; this happens
|
||
automatically if `pem_bundle`, `pem_json`, or `insecure_tls` is set
|
||
|
||
- If `insecure_tls` is set to true, the connection will not perform verification
|
||
of the server certificate; this also sets `tls` to true
|
||
|
||
- If only `issuing_ca` is set in `pem_json`, or the only certificate in
|
||
`pem_bundle` is a CA certificate, the given CA certificate will be used for
|
||
server certificate verification; otherwise the system CA certificates will be
|
||
used
|
||
|
||
- If `certificate` and `private_key` are set in `pem_bundle` or `pem_json`,
|
||
client auth will be turned on for the connection
|
||
|
||
`pem_bundle` should be a PEM-concatenated bundle of a private key + client
|
||
certificate, an issuing CA certificate, or both. `pem_json` should contain the
|
||
same information; for convenience, the JSON format is the same as that output by
|
||
the issue command from the PKI secrets engine.
|
||
|
||
### Sample Payload

||
|
||
```json
|
||
{
|
||
"plugin_name": "influxdb-database-plugin",
|
||
"allowed_roles": "readonly",
|
||
"host": "influxdb1.local",
|
||
"username": "user",
|
||
"password": "pass"
|

```
|
||
|

### Sample Request
|
||
|
||
```
|
||
$ curl \

--header "X-Vault-Token: ..." \
|
||
--request POST \

http://127.0.0.1:8200/v1/influxdb/config/connection
|
||
```
|
||
|
||
## Statements
|
||
|
||
Statements are configured during role creation and are used by the plugin to
|
||
determine what is sent to the database on user creation, renewing, and
|
||
revocation. For more information on configuring roles see the [Role
|
||
API](/api/secret/databases/index.html#create-role) in the database secrets engine docs.
|
||
|
||
### Parameters
|
||
|
||
The following are the statements used by this plugin. If not mentioned in this
|
||
list the plugin does not support that statement type.
|
||
|
||
- `creation_statements` `(list: [])` – Specifies the database
|
||
statements executed to create and configure a user. Must be a
|
||
semicolon-separated string, a base64-encoded semicolon-separated string, a
|
||
serialized JSON string array, or a base64-encoded serialized JSON string
|
||
array. The '{{username}}' and '{{password}}' values will be substituted. If not
|
||
provided, defaults to a generic create user statements that creates a
|
||
non-superuser.
|
||
|
||
- `revocation_statements` `(list: [])` – Specifies the database statements to
|
||
be executed to revoke a user. Must be a semicolon-separated string, a
|
||
base64-encoded semicolon-separated string, a serialized JSON string array, or
|
||
a base64-encoded serialized JSON string array. The '{{username}}' value will be
|
||
substituted. If not provided defaults to a generic drop user statement.
|
||
|
||
- `rollback_statements` `(list: [])` – Specifies the database statements to be
|
||
executed to rollback a create operation in the event of an error. Must be a
|
||
semicolon-separated string, a base64-encoded semicolon-separated string, a
|
||
serialized JSON string array, or a base64-encoded serialized JSON string
|
||
array. The '{{username}}' value will be substituted. If not provided, defaults to
|
||
a generic drop user statement
