+description: |-
+  Manages a CSS load balancing resource within OpenTelekomCloud.
+---
+
+Up-to-date reference of API arguments for CSS load balancing you can get at
+[documentation portal](https://docs.otc.t-systems.com/cloud-search-service/api-ref/apis/load_balancing)
+
+# opentelekomcloud_css_loadbalancer_v1
+
+Manages a CSS configuration of loadbalancer.
+
+## Example Usage
+
+```hcl
+resource "opentelekomcloud_css_loadbalancer_v1" "css_lb" {
+  cluster_id = "terraform-test-cluster"
+  elb_id     = var.elb_id
+  agency     = "css_upgrade_agency"
+
+  listener {
+    protocol       = "HTTPS"
+    protocol_port  = 443
+    server_cert_id = var.server_cert_id
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `cluster_id` - (Required) ID of the CSS cluster.
+
+* `agency` - (Required) The agency used by CSS to access ELB.
+
+* `elb_id` - (Required) ELBv3 ID.
+
+* `listener` - (Optional) configure load balancing listeners for a cluster. Structure is documented below.
+
+The `listener` block supports:
+
+* `protocol` - (Required) Protocol type. HTTP and HTTPS are supported.
+
+* `protocol_port` - (Required) Port.
+
+* `server_cert_id` - (Optional) Server certificate ID. This parameter is mandatory when protocol is set to HTTPS.
+
+* `ca_cert_id` - (Optional) CA certificate ID. This parameter is mandatory when protocol is set to HTTPS and bidirectional authentication is used.
+
+* `type` - (Optional) Type: searchTool indicates that the load balancer is enabled or disabled for Elasticsearch/OpenSearch. viewTool indicates that the load balancer is enabled or disabled for Kibana/OpenSearch Dashboards. The default value is searchTool.
