NAME
gcloud alpha compute instances network-interfaces update - update a Compute Engine virtual machine network interface
SYNOPSIS
gcloud alpha compute instances network-interfaces update INSTANCE_NAME [--aliases=ALIASES] [--external-ipv6-address=EXTERNAL_IPV6_ADDRESS] [--external-ipv6-prefix-length=EXTERNAL_IPV6_PREFIX_LENGTH] [--internal-ipv6-address=INTERNAL_IPV6_ADDRESS] [--internal-ipv6-prefix-length=INTERNAL_IPV6_PREFIX_LENGTH] [--ipv6-address=IPV6_ADDRESS] [--ipv6-network-tier=IPV6_NETWORK_TIER] [--ipv6-prefix-length=IPV6_PREFIX_LENGTH] [--network=NETWORK] [--network-interface=NETWORK_INTERFACE; default="nic0"] [--private-network-ip=PRIVATE_NETWORK_IP] [--security-policy=SECURITY_POLICY] [--security-policy-region=SECURITY_POLICY_REGION] [--stack-type=STACK_TYPE] [--subnetwork=SUBNETWORK] [--zone=ZONE] [GCLOUD_WIDE_FLAG]
DESCRIPTION
(ALPHA) gcloud alpha compute instances network-interfaces update updates network interfaces of a Compute Engine virtual machine. For example:
gcloud alpha compute instances network-interfaces update example-instance --zone us-central1-a --aliases r1:172.16.0.1/32

sets 172.16.0.1/32 from range r1 of the default interface's subnetwork as the interface's alias IP.

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
--aliases=ALIASES
The IP alias ranges to allocate for this interface. If there are multiple IP alias ranges, they are separated by semicolons.

Can be specified together with --network and/or --subnetwork to choose IP alias ranges in the new subnetwork. If unspecified, then the previous IP alias ranges will be allocated in the new subnetwork. If the previous IP alias ranges are not available in the new subnetwork, then other available IP alias ranges of the same size will be allocated in the new subnetwork.

For example:

--aliases="10.128.1.0/24;r1:/32"
--external-ipv6-address=EXTERNAL_IPV6_ADDRESS
Assigns the given external IPv6 address to an instance. The address must be the first IP in the range. This option is applicable only to dual-stack instances with stack-type=IPV4_ONLY.
--external-ipv6-prefix-length=EXTERNAL_IPV6_PREFIX_LENGTH
The prefix length of the external IPv6 address range. This flag should be used together with --external-ipv6-address. Currently only /96 is supported and the default value is 96.
--internal-ipv6-address=INTERNAL_IPV6_ADDRESS
Assigns the given internal IPv6 address or range to an instance. The address must be the first IP address in the range or a /96 IP address range. This option can only be used on a dual stack instance network interface.
--internal-ipv6-prefix-length=INTERNAL_IPV6_PREFIX_LENGTH
Optional field that indicates the prefix length of the internal IPv6 address range, should be used together with --internal-ipv6-address=fd20::. Only /96 IP address range is supported and the default value is 96. If not set, then either the prefix length from --internal-ipv6-address=fd20::/96 will be used or the default value of 96 will be assigned.
--ipv6-address=IPV6_ADDRESS
Assigns the given external IPv6 address to an instance. The address must be the first IP in the range. This option is applicable only to dual-stack instances with stack-type=IPV4_ONLY.
--ipv6-network-tier=IPV6_NETWORK_TIER
Specifies the IPv6 network tier that will be used to configure the instance network interface IPv6 access config. IPV6_NETWORK_TIER must be (only one value is supported):
PREMIUM
High quality, Google-grade network tier.
--ipv6-prefix-length=IPV6_PREFIX_LENGTH
The prefix length of the external IPv6 address range. This flag should be used together with --ipv6-address. Currently only /96 is supported and the default value is 96.
--network=NETWORK
Specifies the network this network interface belongs to.
--network-interface=NETWORK_INTERFACE; default="nic0"
The name of the network interface to update.
--private-network-ip=PRIVATE_NETWORK_IP
Assign the given IP address to the interface. Can be specified only together with --network and/or --subnetwork to choose the IP address in the new subnetwork. If unspecified, then the previous IP address will be allocated in the new subnetwork. If the previous IP address is not available in the new subnetwork, then another available IP address will be allocated automatically from the new subnetwork CIDR range.
--security-policy=SECURITY_POLICY
The security policy that will be set for this instance network interface. To remove the policy from this instance network interface set the policy to an empty string.
--security-policy-region=SECURITY_POLICY_REGION
Region of the security policy to operate on. Overrides the default compute/region property value for this command invocation.
--stack-type=STACK_TYPE
The stack type for the default network interface. Determines if IPv6 is enabled on the default network interface. STACK_TYPE must be one of:
IPV4_IPV6
The network interface can have both IPv4 and IPv6 addresses.
IPV4_ONLY
The network interface will be assigned IPv4 addresses.
--subnetwork=SUBNETWORK
Specifies the subnetwork this network interface belongs to.
--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.

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.

NOTES
This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist. These variants are also available:
gcloud compute instances network-interfaces update
gcloud beta compute instances network-interfaces update
