## Requirements

The below requirements are needed on the host that executes this module.

- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---

all_ports
boolean
added in 2.8

Choices:
- no
- yes

For internal TCP/UDP load balancing (i.e. load balancing scheme is INTERNAL and protocol is TCP/UDP), set this to true to allow packets addressed to any ports to be forwarded to the backends configured with this forwarding rule. Used with backend service. Cannot be set if port or portRange are set.

auth_kind
string / required

Choices:
- application
- machineaccount
- serviceaccount

The type of credential used.

backend_service
dictionary

A BackendService to receive the matched traffic. This is used only for INTERNAL load balancing.
This field represents a link to a BackendService resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_backend_service task and then set this backend_service field to "{{ name-of-resource }}"

description string |  | An optional description of this resource. Provide this property when you create the resource.
env_type string |  | Specifies which Ansible environment you're running this module within. This should not be set unless you know what you're doing. This only alters the User Agent string for any API requests.

ip_address
string

The IP address that this forwarding rule is serving on behalf of.
Addresses are restricted based on the forwarding rule's load balancing scheme (EXTERNAL or INTERNAL) and scope (global or regional).
When the load balancing scheme is EXTERNAL, for global forwarding rules, the address must be a global IP, and for regional forwarding rules, the address must live in the same region as the forwarding rule. If this field is empty, an ephemeral IPv4 address from the same scope (global or regional) will be assigned. A regional forwarding rule supports IPv4 only. A global forwarding rule supports either IPv4 or IPv6.
When the load balancing scheme is INTERNAL, this can only be an RFC 1918 IP address belonging to the network/subnet configured for the forwarding rule. By default, if this field is empty, an ephemeral internal IP address will be automatically allocated from the IP range of the subnet or network configured for this forwarding rule.
An address can be specified either by a literal IP address or a URL reference to an existing Address resource. The following examples are all valid: * 100.1.2.3 * https://www.googleapis.com/compute/v1/projects/project/regions/region/addresses/address * projects/project/regions/region/addresses/address * regions/region/addresses/address * global/addresses/address * address .

ip_protocol string |  | The IP protocol to which this rule applies. Valid options are TCP, UDP, ESP, AH, SCTP or ICMP. When the load balancing scheme is INTERNAL, only TCP and UDP are valid. Some valid choices include: "TCP", "UDP", "ESP", "AH", "SCTP", "ICMP"
ip_version string |  | ipVersion is not a valid field for regional forwarding rules. Some valid choices include: "IPV4", "IPV6"

load_balancing_scheme
string

This signifies what the ForwardingRule will be used for and can only take the following values: INTERNAL, EXTERNAL The value of INTERNAL means that this will be used for Internal Network Load Balancing (TCP, UDP). The value of EXTERNAL means that this will be used for External Load Balancing (HTTP(S) LB, External TCP/UDP LB, SSL Proxy) .
Some valid choices include: "INTERNAL", "EXTERNAL"

name
string / required

Name of the resource; provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.

network
dictionary

For internal load balancing, this field identifies the network that the load balanced IP should belong to for this Forwarding Rule. If this field is not specified, the default network will be used.
This field is only used for INTERNAL load balancing.
This field represents a link to a Network resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_network task and then set this network field to "{{ name-of-resource }}"

network_tier string added in 2.8 |  | The networking tier used for configuring this address. This field can take the following values: PREMIUM or STANDARD. If this field is not specified, it is assumed to be PREMIUM. Some valid choices include: "PREMIUM", "STANDARD"

port_range
string

This field is used along with the target field for TargetHttpProxy, TargetHttpsProxy, TargetSslProxy, TargetTcpProxy, TargetVpnGateway, TargetPool, TargetInstance.
Applicable only when IPProtocol is TCP, UDP, or SCTP, only packets addressed to ports in the specified range will be forwarded to target.
Forwarding rules with the same [IPAddress, IPProtocol] pair must have disjoint port ranges.
Some types of forwarding target have constraints on the acceptable ports: * TargetHttpProxy: 80, 8080 * TargetHttpsProxy: 443 * TargetTcpProxy: 25, 43, 110, 143, 195, 443, 465, 587, 700, 993, 995, 1883, 5222 * TargetSslProxy: 25, 43, 110, 143, 195, 443, 465, 587, 700, 993, 995, 1883, 5222 * TargetVpnGateway: 500, 4500 .

ports list |  | This field is used along with the backend_service field for internal load balancing. When the load balancing scheme is INTERNAL, a single port or a comma separated list of ports can be configured. Only packets addressed to these ports will be forwarded to the backends configured with this forwarding rule. You may specify a maximum of up to 5 ports.
project string |  | The Google Cloud Platform project to use.
region string / required |  | A reference to the region where the regional forwarding rule resides. This field is not applicable to global forwarding rules.
scopes list |  | Array of scopes to be used.
service_account_contents jsonarg |  | The contents of a Service Account JSON file, either in a dictionary or as a JSON string that represents it.
service_account_email string |  | An optional service account email address if machineaccount is selected and the user does not wish to use the default email.
service_account_file path |  | The path of a Service Account JSON file if serviceaccount is selected as type.

service_label
string
added in 2.8

An optional prefix to the service name for this Forwarding Rule.
If specified, will be the first label of the fully qualified service name.
The label must be 1-63 characters long, and comply with RFC1035.
Specifically, the label must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
This field is only used for INTERNAL load balancing.

state
string

Choices:
- present ←
- absent

subnetwork
dictionary

The subnetwork that the load balanced IP should belong to for this Forwarding Rule. This field is only used for INTERNAL load balancing.
If the network specified is in auto subnet mode, this field is optional. However, if the network is in custom subnet mode, a subnetwork must be specified.
This field represents a link to a Subnetwork resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_subnetwork task and then set this subnetwork field to "{{ name-of-resource }}"

target
dictionary
added in 2.7

This field is only used for EXTERNAL load balancing.
A reference to a TargetPool resource to receive the matched traffic.
This target must live in the same region as the forwarding rule.
The forwarded traffic must be of a type appropriate to the target object.
This field represents a link to a TargetPool resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'selfLink' and value of your resource's selfLink Alternatively, you can add `register: name-of-resource` to a gcp_compute_target_pool task and then set this target field to "{{ name-of-resource }}"
