The Influxdb plugin for Vault's database secrets engine generates database credentials to access Influxdb servers.

# 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 \
--data @payload.json \
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
