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
ip_protocol:
description:
- 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.
required: false
choices: ['TCP', 'UDP', 'ESP', 'AH', 'SCTP', 'ICMP']
backend_service:
description:
- A reference to BackendService resource.
required: false
ip_version:
description:
- The IP Version that will be used by this forwarding rule. Valid options are IPV4
or IPV6. This can only be specified for a global forwarding rule.
required: false
choices: ['IPV4', 'IPV6']
load_balancing_scheme:
description:
- '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)
.'
required: false
choices: ['INTERNAL', 'EXTERNAL']
name:
description:
- 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.
required: true
network:
description:
- A reference to Network 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, 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 .'
required: false
ports:
description:
- 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.
required: false

description:
