+title: Provision an RDS instance with more than one database
+---
+
+In the guide [Provision and Binding Cloud Resources](./provision-and-consume-cloud-services) and [Provision a Database and Import a SQL File for initialization](./provision-and-initiate-database),
+only one database will be created in an RDS instance. This tutorial will show you how to create more than one database in an RDS instance.
+
+In the [reference doc for Alibaba Cloud RDS](./terraform/alibaba-rds), set `database_name` if you want to create one database.
+If you want to create more than one database, set `databases` to array of databases. Each database is a map, the map
+contains the following attributes: name, character_set, description.
+
+```
+[
+    {
+      "name" : "test",
+      "character_set" : "utf8",
+      "description" : "test database"
+    },
+    {
+      "name" : "test2",
+      "character_set" : "utf8",
+      "description" : "test database"
+    }
+  ]
+```

It conflicts with `database_name`. | list(map(string)) | false    |         |
+
+Applying the following application can create more than one database in an RDS instance.
