NAME
gcloud alpha compute security-policies add-user-defined-field - add a user defined field to a Compute Engine security policy
SYNOPSIS
gcloud alpha compute security-policies add-user-defined-field NAME --base=BASE --offset=OFFSET --size=SIZE --user-defined-field-name=USER_DEFINED_FIELD_NAME [--mask=MASK] [--region=REGION] [GCLOUD_WIDE_FLAG]
DESCRIPTION
(ALPHA) gcloud alpha compute security-policies add-user-defined-field is used to add user defined fields to security policies.
EXAMPLES
To add a user defined field run this:
gcloud alpha compute security-policies add-user-defined-field SECURITY_POLICY --user-defined-field-name=my-field --base=ipv6 --offset=10 --size=3
POSITIONAL ARGUMENTS
NAME
Name of the security policy to update.
REQUIRED FLAGS
--base=BASE
The base relative to which offset is measured. BASE must be one of: ipv4, ipv6, tcp, udp.
--offset=OFFSET
Offset of the first byte of the field (in network byte order) relative to base.
--size=SIZE
Size of the field in bytes. Valid values: 1-4.
--user-defined-field-name=USER_DEFINED_FIELD_NAME
The name for the user defined field.
OPTIONAL FLAGS
--mask=MASK
If specified, apply this mask (bitwise AND) to the field to ignore bits before matching. Encoded as a hexadecimal number (starting with "0x").
--region=REGION
Region of the security policy to update. Overrides the default compute/region property value for this command invocation.
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:
