+
+# cloudstack_pod
+
+Creates an internal load balancer.
+
+## Example Usage
+
+Basic usage:
+
+```hcl
+resource "cloudstack_loadbalancer" "example" {
+  algorithm                = "Source"
+  description              = "Example Load Balancer"
+  instanceport             = "8081"
+  name                     = "internal-lb-example"
+  networkid                = "0ae8fa84-c78e-441a-8628-917d276c7d5c"
+  scheme                   = "Internal"
+  sourceipaddressnetworkid = "0ae8fa84-c78e-441a-8628-917d276c7d5c"
+  sourceport               = "8081"
+  virtualmachineids        = [ "48600f99-d890-472c-bc1a-7379af22727c", "749485a1-4081-49cd-9668-1d160ac94488", "9bbf3c6d-c8b8-42e8-ab37-e4f60a71f61d" ]
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `algorithm` - (Required) load balancer algorithm (source, roundrobin, leastconn).
+* `description` - (Optional) the description of the load balancer.
+* `instanceport` - (Required) the TCP port of the virtual machine where the network traffic will be load balanced to.
+* `name` - (Required) name of the load balancer.
+* `networkid` - (Required) The guest network the load balancer will be created for.
+* `scheme` - (Required) the load balancer scheme. Supported value in this release is Internal.
+* `sourceipaddressnetworkid` - (Required) the network id of the source ip address.
+* `sourceport` - (Required) the source port the network traffic will be load balanced from.
+* `sourceipaddress` - (Optional) the source IP address the network traffic will be load balanced from.
+* `virtualmachineids` - (Optional) the list of IDs of the virtual machine that are being assigned to the load balancer rule(i.e. virtualMachineIds=1,2,3).
+
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - the Load Balancer ID.
+
+
+
+## Import
+
+A pod can be imported; use `<LOADBALANCER ID>` as the import ID. For
+example:
+
+```shell
+terraform import cloudstack_loadbalancer.example eefce154-e759-45a4-989a-9a432792801b
+```
