# google\_compute\_forwarding\_rule
Manages a Forwarding Rule within GCE. This binds an ip and port range to a target pool. For more
information see [the official
documentation](https://cloud.google.com/compute/docs/load-balancing/network/forwarding-rules) and
[API](https://cloud.google.com/compute/docs/reference/latest/forwardingRules).
## Example Usage
```
resource "google_compute_forwarding_rule" "default" {
name = "test"
target = "${google_compute_target_pool.default.self_link}"
port_range = "80"
}
```
## Argument Reference
The following arguments are supported:
* `description` - (Optional) Textual description field.
* `ip_address` - (Optional) The static IP. (if not set, an ephemeral IP is
used).
* `ip_protocol` - (Optional) The IP protocol to route, one of "TCP" "UDP" "AH" "ESP" or "SCTP". (default "TCP").
* `name` - (Required) A unique name for the resource, required by GCE. Changing
this forces a new resource to be created.
* `port_range` - (Optional) A range e.g. "1024-2048" or a single port "1024"
(defaults to all ports!).
* `target` - URL of target pool.
## Attributes Reference
The following attributes are exported:
* `self_link` - The URL of the created resource.
* `ip_address` - The IP address that was chosen (or specified).

Manages an HTTP Health Check within GCE.
---
# google\_compute\_http\_health\_check
Manages an HTTP health check within GCE. This is used to monitor instances
behind load balancers. Timeouts or HTTP errors cause the instance to be
removed from the pool. For more information, see [the official
documentation](https://cloud.google.com/compute/docs/load-balancing/health-checks)
and
[API](https://cloud.google.com/compute/docs/reference/latest/httpHealthChecks).
## Example Usage
```
resource "google_compute_http_health_check" "default" {
name = "test"
request_path = "/health_check"
check_interval_sec = 1
timeout_sec = 1
}
```
## Argument Reference
The following arguments are supported:
* `check_interval_sec` - (Optional) How often to poll each instance (default 5).
* `description` - (Optional) Textual description field.
* `healthy_threshold` - (Optional) Consecutive successes required (default 2).
* `host` - (Optional) HTTP host header field (default instance's public ip).
* `name` - (Required) A unique name for the resource, required by GCE.
Changing this forces a new resource to be created.
* `port` - (Optional) TCP port to connect to (default 80).
* `request_path` - (Optional) URL path to query (default /).
* `timeout_sec` - (Optional) How long before declaring failure (default 5).
* `unhealthy_threshold` - (Optional) Consecutive failures required (default 2).
## Attributes Reference
The following attributes are exported:
* `self_link` - The URL of the created resource.

# google\_compute\_target\_pool
Manages a Target Pool within GCE. This is a collection of instances used as
target of a network load balancer (Forwarding Rule). For more information see
[the official
documentation](https://cloud.google.com/compute/docs/load-balancing/network/target-pools)
and [API](https://cloud.google.com/compute/docs/reference/latest/targetPools).
## Example Usage
```
resource "google_compute_target_pool" "default" {
name = "test"
instances = [ "us-central1-a/myinstance1", "us-central1-b/myinstance2" ]
health_checks = [ "${google_compute_http_health_check.default.name}" ]
}
```
## Argument Reference
The following arguments are supported:
* `backup_pool` - (Optional) URL to the backup target pool. Must also set
failover\_ratio.
* `description` - (Optional) Textual description field.
* `failover_ratio` - (Optional) Ratio (0 to 1) of failed nodes before using the
backup pool (which must also be set).
* `health_checks` - (Optional) List of zero or one healthcheck names.
* `instances` - (Optional) List of instances in the pool. They can be given as
URLs, or in the form of "zone/name". Note that the instances need not exist
at the time of target pool creation, so there is no need to use the Terraform
interpolators to create a dependency on the instances from the target pool.
* `name` - (Required) A unique name for the resource, required by GCE. Changing
this forces a new resource to be created.
* `session_affinity` - (Optional) How to distribute load. Options are "NONE" (no affinity). "CLIENT\_IP" (hash of the source/dest addresses / ports), and "CLIENT\_IP\_PROTO" also includes the protocol (default "NONE").
## Attributes Reference
The following attributes are exported:
* `self_link` - The URL of the created resource.
