## Environment variables
|
||
|
|
|
||
|
|
### `SQLD_NODE`
|
||
|
|
|
||
|
|
The `SQLD_NODE` environment variable configures the type of the launched instance. Possible values are: `primary` (default), `replica`, and `standalone`.
|
||
|
|
Please note that replica instances also need the `SQLD_PRIMARY_URL` environment variable to be defined.
|
||
|
|
|
||
|
|
### `SQLD_PRIMARY_URL`
|
||
|
|
|
||
|
|
The `SQLD_PRIMARY_URL` environment variable configures the gRPC URL of the primary instance for replica instances.

||
|
