NAME
gcloud compute instances update-access-config - update a Compute Engine virtual machine access configuration
SYNOPSIS
gcloud compute instances update-access-config INSTANCE_NAME [--network-interface=NETWORK_INTERFACE; default="nic0"] [--zone=ZONE] [--no-ipv6-public-ptr     | --ipv6-public-ptr-domain=IPV6_PUBLIC_PTR_DOMAIN] [--public-ptr     | --no-public-ptr] [--public-ptr-domain=PUBLIC_PTR_DOMAIN     | --no-public-ptr-domain] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
gcloud compute instances update-access-config is used to update access configurations for network interfaces of Compute Engine virtual machines. IPv4 and IPv6 access configurations cannot be updated together.
EXAMPLES
To update public PTR record in IPv4 access config in network interface 'nic0' of an instance, run: 
gcloud compute instances update-access-config example-instance --network-interface=nic0 --zone=us-central1-b --public-ptr --public-ptr-domain=exampledomain.com.

To update public PTR record in IPv6 access config in default network interface 'nic0' of an instance, run: 

gcloud compute instances update-access-config example-instance --zone=us-central1-b --ipv6-public-ptr-domain=exampledomain.com.
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
FLAGS
--network-interface=NETWORK_INTERFACE; default="nic0"
Specifies the name of the network interface which contains the access configuration. If this is not provided, then "nic0" is used as the default.
--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. At most one of these can be specified:
--no-ipv6-public-ptr
If provided, the default DNS PTR record will replace the existing one for external IPv6 in the IPv6 access configuration. Mutually exclusive with ipv6-public-ptr-domain.
--ipv6-public-ptr-domain=IPV6_PUBLIC_PTR_DOMAIN
Assigns a custom PTR domain for the external IPv6 in the access configuration. Mutually exclusive with no-ipv6-public-ptr. This option can only be specified for the default network interface, nic0.
At most one of these can be specified:
--public-ptr
Creates a DNS PTR record for the external IP in the access configuration. This option can only be specified for the default network-interface, "nic0".
--no-public-ptr
If provided, no DNS PTR record is created for the external IP in the access configuration. Mutually exclusive with public-ptr-domain.
At most one of these can be specified:
--public-ptr-domain=PUBLIC_PTR_DOMAIN
Assigns a custom PTR domain for the external IP in the access configuration. Mutually exclusive with no-public-ptr. This option can only be specified for the default network-interface, "nic0".
--no-public-ptr-domain
If both this flag and --public-ptr are specified, creates a DNS PTR record for the external IP in the access configuration with the PTR domain name being the DNS name of the instance.
GCLOUD WIDE FLAGS
These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.

Run $ gcloud help for details.
