gcloud compute start-iap-tunnel

NAME: gcloud compute start-iap-tunnel - starts an IAP TCP forwarding tunnel
SYNOPSIS: gcloud compute start-iap-tunnel INSTANCE_NAME INSTANCE_PORT [--iap-tunnel-disable-connection-check] [--local-host-port=LOCAL_HOST_PORT; default="localhost:0"] [--zone=ZONE] [--network=NETWORK --region=REGION : --dest-group=DEST_GROUP] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: Starts a tunnel to Cloud Identity-Aware Proxy for TCP forwarding through which another process can create a connection (eg. SSH, RDP) to a Google Compute Engine instance.
To learn more, see the IAP for TCP forwarding documentation.
If the --region and --network flags are provided, then an IP address or FQDN must be supplied instead of an instance name. This is most useful for connecting to on-prem resources.
EXAMPLES: To open a tunnel to the instances's RDP port on an arbitrary local port, run:
gcloud compute start-iap-tunnel my-instance 3389

To open a tunnel to the instance's RDP port on a specific local port, run:
gcloud compute start-iap-tunnel my-instance 3389 --local-host-port=localhost:3333

To use the IP address or FQDN of your remote VM (eg, for on-prem), you must also specify the --region and --network flags:
gcloud compute start-iap-tunnel 10.1.2.3 3389 --region=us-central1 --network=default
POSITIONAL ARGUMENTS: INSTANCE_NAME

Name of the instance to operate on. For details on valid instance names, refer to the criteria documented under the field 'name' at: https://cloud.google.com/compute/docs/reference/rest/v1/instances

INSTANCE_PORT

The name or number of the instance's port to connect to.
FLAGS: --iap-tunnel-disable-connection-check

Disables the immediate check of the connection.

--local-host-port=LOCAL_HOST_PORT; default="localhost:0"

LOCAL_HOST:LOCAL_PORT on which gcloud should bind and listen for connections that should be tunneled.
LOCAL_PORT may be omitted, in which case it is treated as 0 and an arbitrary unused local port is chosen. The colon also may be omitted in that case.
If LOCAL_PORT is 0, an arbitrary unused local port is chosen.

--zone=ZONE

Zone of the instance to operate on. If not specified, you might be prompted to select a zone (interactive mode only). gcloud attempts to identify the appropriate zone by searching for resources in your currently active project. If the zone cannot be determined, gcloud prompts you for a selection with all available Google Cloud Platform zones.
To avoid prompting when this flag is omitted, the user 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.

--network=NETWORK

Configures the VPC network to use when connecting via IP address or FQDN.

--region=REGION

Configures the region to use when connecting via IP address or FQDN.

--dest-group=DEST_GROUP

Configures the destination group to use when connecting via IP address or FQDN.
