+# huaweicloud_cse_microservice_engine_configurations
+
+Use this data source to query managed microservice engine configurations within HuaweiCloud.
+
+## Example Usage
+
+```hcl
+data "huaweicloud_cse_microservice_engine_configurations" "test" {}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `auth_address` - (Required, String) Specifies the address that used to request the access token.  
+  Changing this will create a new resource.
+
+* `connect_address` - (Required, String) Specifies the address that used to access engine and manages
+  configuration.  
+  Changing this will create a new resource.
+
+-> We are only support IPv4 addresses yet (for `auth_address` and `connect_address`).
+
+* `admin_user` - (Optional, String) Specifies the account name for **RBAC** login.
+
+* `admin_pass` - (Optional, String) Specifies the account password for **RBAC** login.
+  The password format must meet the following conditions:
+  + Must be `8` to `32` characters long.
+  + A password must contain at least one digit, one uppercase letter, one lowercase letter, and one special character
+    (-~!@#%^*_=+?$&()|<>{}[]).
+  + Cannot be the account name or account name spelled backwards.
+  + The password can only start with a letter.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `configurations` - All queried configurations of the dedicated microservice engine.  
+  The [configurations](#cse_microservice_engine_configurations) structure is documented below.
+
+<a name="cse_microservice_engine_configurations"></a>
+The `configurations` block supports:
+
+* `id` - The ID of the microservice engine configuration.
+
+* `key` - The configuration key (item name).
+
+* `value_type` - The type of the configuration value.
+  + **ini**
+  + **json**
+  + **text**
+  + **yaml**
+  + **properties**
+  + **xml**
+
+* `value` - The configuration value.
+
+* `status` - The configuration status.
+  + **enabled**
+  + **disabled**
+
+* `tags` - The key/value pairs to associate with the configuration that used to filter resource.
+
+* `created_at` - The creation time of the configuration, in RFC3339 format.
+
+* `updated_at` - The latest update time of the configuration, in RFC3339 format.
+
+* `create_revision` - The create version of the configuration.
+
+* `update_revision` - The update version of the configuration.
