module: gcp_compute_forwarding_rule
description:
- A ForwardingRule resource. A ForwardingRule resource specifies which pool of target
virtual machines to forward a packet to if it matches the given [IPAddress, IPProtocol,
portRange] tuple.
short_description: Creates a GCP ForwardingRule
version_added: 2.6
author: Google Inc. (@googlecloudplatform)
requirements:
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0
options:
state:
description:
- Whether the given object should exist in GCP
choices:
- present
- absent
default: present
description:
description:
- An optional description of this resource. Provide this property when you create
the resource.
required: false
ip_address:
description:
- 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
* U(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 .'
required: false

AH, SCTP or ICMP.
- When the load balancing scheme is INTERNAL, only TCP and UDP are valid.
required: false
choices:
- TCP
- UDP
- ESP
- AH
- SCTP
- ICMP
backend_service:
description:
- 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 }}"'
required: false
ip_version:

required: false
choices:
- IPV4
- IPV6

means that this will be used for External Load Balancing (HTTP(S) LB, External
TCP/UDP LB, SSL Proxy) .'
required: false
choices:
- INTERNAL
- EXTERNAL
name:
description:

characters must be a dash, lowercase letter, or digit, except the last character,
which cannot be a dash.

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
}}"'
required: false
port_range:
description:
- 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,

500, 4500 .'
required: false
ports:
description:
- This field is used along with the backend_service field for internal load balancing.

be forwarded to the backends configured with this forwarding rule.
- You may specify a maximum of up to 5 ports.
required: false
subnetwork:
description:
- 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`

description:
- 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
