DESCRIPTION

gcloud compute forwarding-rules set-target is used to set a new target for a forwarding rule. A forwarding rule directs traffic that matches a destination IP address (and possibly a TCP or UDP port) to a forwarding target (load balancer, VPN gateway or VM instance).

Forwarding rules can be either global or regional, specified with the --global or --region=REGION flags. For more information about the scope of a forwarding rule, refer to https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts.

Forwarding rules can be external, internal, internal managed, or internal self-managed, specified with the --load-balancing-scheme=[EXTERNAL|EXTERNAL_MANAGED|INTERNAL|INTERNAL_MANAGED|INTERNAL_SELF_MANAGED] flag. External forwarding rules are accessible from the internet, while internal forwarding rules are only accessible from within their VPC networks. You can specify a reserved static external or internal IP address with the --address=ADDRESS flag for the forwarding rule. Otherwise, if the flag is unspecified, an ephemeral IP address is automatically assigned (global IP addresses for global forwarding rules and regional IP addresses for regional forwarding rules); an internal forwarding rule is automatically assigned an ephemeral internal IP address from the subnet specified with the --subnet flag. You must provide an IP address for an internal self-managed forwarding rule.

Different types of load balancers work at different layers of the OSI networking model (http://en.wikipedia.org/wiki/Network_layer). Layer 3/4 targets include target pools, target SSL proxies, target TCP proxies, and backend services. Layer 7 targets include target HTTP proxies and target HTTPS proxies. For more information, refer to https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts.

When creating a forwarding rule, exactly one of  `_--target-instance_`,
`_--target-pool_`, `_--target-http-proxy_`, `_--target-https-proxy_`,
`_--target-grpc-proxy_`, `_--target-ssl-proxy_`,
`_--target-tcp-proxy_` or `_--target-vpn-gateway_`
must be specified.

POSITIONAL ARGUMENTS

NAME

Name of the forwarding rule to operate on.

REQUIRED FLAGS

Exactly one of these must be specified:

--backend-service=BACKEND_SERVICE

Target backend service that receives the traffic.

--target-grpc-proxy=TARGET_GRPC_PROXY

Target gRPC proxy that receives the traffic.

--target-http-proxy=TARGET_HTTP_PROXY

Target HTTP proxy that receives the traffic. For the acceptable ports, see Port specifications.

--target-https-proxy=TARGET_HTTPS_PROXY

Target HTTPS proxy that receives the traffic. For the acceptable ports, see Port specifications.

--target-instance=TARGET_INSTANCE

Name of the target instance that receives the traffic. The target instance must be in a zone in the forwarding rule's region. Global forwarding rules cannot direct traffic to target instances. If not specified and the compute/zone property isn't set, you might be prompted to select a zone (interactive mode only).

To avoid prompting when this flag is omitted, you can set the compute/zone property:

gcloud config set compute/zone ZONE

A list of zones can be fetched by running:

gcloud compute zones list

To unset the property, run:

gcloud config unset compute/zone

Alternatively, the zone can be stored in the environment variable CLOUDSDK_COMPUTE_ZONE.

--target-pool=TARGET_POOL

Target pool that receives the traffic. The target pool must be in the same region as the forwarding rule. Global forwarding rules cannot direct traffic to target pools.

--target-ssl-proxy=TARGET_SSL_PROXY

Target SSL proxy that receives the traffic. For the acceptable ports, see Port specifications.

--target-tcp-proxy=TARGET_TCP_PROXY

Target TCP proxy that receives the traffic. For the acceptable ports, see Port specifications.

--target-vpn-gateway=TARGET_VPN_GATEWAY

Target VPN gateway (Cloud VPN Classic gateway) that receives forwarded traffic. Acceptable values for --ports flag are: 500, 4500.

OPTIONAL FLAGS

--load-balancing-scheme=LOAD_BALANCING_SCHEME; default="EXTERNAL"

(DEPRECATED) This defines the forwarding rule's load balancing scheme.

The --load-balancing-scheme option is deprecated and will be removed in an upcoming release. If you're currently using this argument, you should remove it from your workflows. LOAD_BALANCING_SCHEME must be one of:

EXTERNAL

EXTERNAL_MANAGED

Global and regional external Application Load Balancers, and regional external proxy Network Load Balancers, used with --target-http-proxy, --target-https-proxy, --target-tcp-proxy.

INTERNAL

INTERNAL_MANAGED

Internal Application Load Balancers and internal proxy Network Load Balancers, used with --target-http-proxy, --target-https-proxy, --target-tcp-proxy.

INTERNAL_SELF_MANAGED

Traffic Director, used with --target-http-proxy, --target-https-proxy, --target-grpc-proxy, --target-tcp-proxy.

--network=NETWORK

(DEPRECATED) Only for --load-balancing-scheme=INTERNAL or --load-balancing-scheme=INTERNAL_SELF_MANAGED or --load-balancing-scheme=EXTERNAL_MANAGED (regional) or --load-balancing-scheme=INTERNAL_MANAGED) Network that this forwarding rule applies to. If this field is not specified, the default network is used. In the absence of the default network, this field must be specified.

The --network option is deprecated and will be removed in an upcoming release. If you're currently using this argument, you should remove it from your workflows.

--subnet=SUBNET

(DEPRECATED) Only for --load-balancing-scheme=INTERNAL and --load-balancing-scheme=INTERNAL_MANAGED) Subnetwork that this forwarding rule applies to. If the network is auto mode, this flag is optional. If the network is custom mode, this flag is required.

The --subnet option is deprecated and will be removed in an upcoming release. If you're currently using this argument, you should remove it from your workflows.

--subnet-region=SUBNET_REGION

(DEPRECATED) Region of the subnetwork to operate on. If not specified, the region is set to the region of the forwarding rule. Overrides the default compute/region property value for this command invocation.

The --subnet-region option is deprecated and will be removed in an upcoming release. If you're currently using this argument, you should remove it from your workflows.
