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. Acceptable values for
--ports flag are: 80, 8080.
--target-https-proxy=TARGET_HTTPS_PROXY
Target HTTPS proxy that receives the traffic. Acceptable values for
--ports flag are: 443.
--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
(https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts#port_specifications).
--target-tcp-proxy=TARGET_TCP_PROXY
Target TCP proxy that receives the traffic. For the acceptable ports,
see Port specifications
(https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts#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 load balancing or forwarding, used with one of
--target-http-proxy, --target-https-proxy, --target-tcp-proxy,
--target-ssl-proxy, --target-pool, --target-vpn-gateway,
--target-instance.
EXTERNAL_MANAGED
Envoy based External HTTP(S) Load Balancing, used with
--target-http-proxy, --target-https-proxy.
INTERNAL
Internal load balancing or forwarding, used with --backend-service.
INTERNAL_MANAGED
Internal load balancing, used with --target-http-proxy,
--target-https-proxy, --target-tcp-proxy.
INTERNAL_SELF_MANAGED
Traffic Director load balancing or forwarding, 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.
--target-instance-zone=TARGET_INSTANCE_ZONE
