gcp_compute_forwarding_rule - Creates a GCP ForwardingRule

New in version 2.6.

Synopsis

  • 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.

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
auth_kind
required
    Choices:
  • machineaccount
  • serviceaccount
  • application
The type of credential used.
backend_service
A reference to a BackendService to receive the matched traffic.
This is used for internal load balancing.
(not used for external load balancing) .
description
An optional description of this resource. Provide this property when you create the resource.
ip_address
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
    Choices:
  • TCP
  • UDP
  • ESP
  • AH
  • SCTP
  • ICMP
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.
ip_version
    Choices:
  • IPV4
  • IPV6
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.
load_balancing_scheme
    Choices:
  • INTERNAL
  • EXTERNAL
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) .
name
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
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 not used for external load balancing.
port_range
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
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 Default:
None
The Google Cloud Platform project to use.
region
required
A reference to the region where the regional forwarding rule resides.
This field is not applicable to global forwarding rules.
scopes
Array of scopes to be used.
service_account_email
An optional service account email address if machineaccount is selected and the user does not wish to use the default email.
service_account_file
The path of a Service Account JSON file if serviceaccount is selected as type.
state
    Choices:
  • present ←
  • absent
Whether the given object should exist in GCP
subnetwork
A reference to a subnetwork.
For internal load balancing, this field identifies the subnetwork that the load balanced IP should belong to for this Forwarding Rule.
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 is not used for external load balancing.
target
(added in 2.7)
A reference to a TargetPool resource to receive the matched traffic.
For regional forwarding rules, this target must live in the same region as the forwarding rule. For global forwarding rules, this target must be a global load balancing resource. The forwarded traffic must be of a type appropriate to the target object.
This field is not used for internal load balancing.
