DESCRIPTION

Creates a secondary VNIC and attaches it to the specified instance. You can specify either –subnet-id or –vlan-id for this create request, but not both. For more information about secondary VNICs, see Virtual Network Interface Cards (VNICs) <https://docs.cloud.oracle.com/iaas/Content/Network/Tasks/managingVNICs.htm>.

USAGE

oci compute instance attach-vnic [OPTIONS]

REQUIRED PARAMETERS

--instance-id [text]

    The OCID of the instance.

OPTIONAL PARAMETERS

--assign-private-dns-record [boolean]

    Whether the VNIC should be assigned a DNS record. If set to false, no DNS record registion for the VNIC; if set to true, DNS record will be registered. The default value is true.

--assign-public-ip [boolean]

    Whether the VNIC should be assigned a public IP address. Defaults to whether the subnet is public or private. If not set and the VNIC is being created in a private subnet (i.e., where prohibitPublicIpOnVnic=true in the Subnet), then no public IP address is assigned. If not set and the subnet is public (prohibitPublicIpOnVnic=false), then a public IP address is assigned. If set to true and prohibitPublicIpOnVnic=true, an error is returned.

--defined-tags [complex type]

    Defined tags for this resource. Each key is predefined and scoped to a namespace. For more information, see Resource Tags <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/resourcetags.htm>. Example: {“Operations”: {“CostCenter”: “42”}} This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

    The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--freeform-tags [complex type]

    Free-form tags for this resource. Each tag is a simple key-value pair with no predefined name, type, or namespace. For more information, see Resource Tags <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/resourcetags.htm>. Example: {“Department”: “Finance”} This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

    The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--from-json [text]

    Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

    The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

    Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

    For examples on usage of this option, please see our “using CLI with advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--hostname-label [text]

    The hostname for the VNIC. Used for DNS. The value is the hostname portion of the VNIC’s fully qualified domain name (FQDN) (e.g., bminstance-1 in FQDN bminstance-1.subnet123.vcn1.oraclevcn.com). Must be unique across all VNICs in the subnet and comply with RFC 952 <https://tools.ietf.org/html/rfc952> (https://tools.ietf.org/html/rfc952) and RFC 1123 <https://tools.ietf.org/html/rfc1123> (https://tools.ietf.org/html/rfc1123). The value can be retrieved from the Vnic <https://docs.cloud.oracle.com/api/#/en/iaas/latest/Vnic/> (#/en/iaas/20160918/Vnic/).

--nic-index [integer]

    Which physical network interface card (NIC) the VNIC will use. Defaults to 0. Certain bare metal instance shapes have two active physical NICs (0 and 1). If you add a secondary VNIC to one of these instances, you can specify which NIC the VNIC will use.

--nsg-ids [complex type]

    A list of the [OCIDs] of the network security groups (NSGs) to add the VNIC to.. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

    The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--private-ip [text]

    A private IP address of your choice to assign to the VNIC. Must be an available IP address within the subnet’s CIDR. If no value is specified, a private IP address from the subnet will be automatically assigned.

--skip-source-dest-check [boolean]

    Indicates whether Source/Destination check is disabled on the VNIC. Defaults to false, in which case we enable Source/Destination check on the VNIC.

--subnet-id [text]

    The OCID of the subnet to create the VNIC in. You can specify either this parameter or –vlan-id, but not both.

--vlan-id [text]

    The OCID of the VLAN to create the VNIC in. You can specify either this parameter or –subnet-id, but not both.

--vnic-display-name [text]

    A user-friendly name for the VNIC. Does not have to be unique.

--wait

    If set, then wait for the attachment to complete and return the newly attached VNIC. If not set, then the command will not wait and will return nothing on success.

GLOBAL PARAMETERS

Use oci --help for help on global parameters.

--auth-purpose, --auth, --cert-bundle, --cli-rc-file, --config-file, --debug, --defaults-file, --endpoint, --generate-full-command-json-input, --generate-param-json-input, --help, --latest-version, --max-retries, --no-retry, --opc-client-request-id, --opc-request-id, --output, --profile, --query, --raw-output, --region, --release-info, --request-id, --version, -?, -d, -h, -v

EXAMPLES

Copy the following CLI commands into a file named example.sh. Run the command by typing “bash example.sh” and replacing the example parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-like shell. You need to set up the OCI configuration <https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/cliinstall.htm#configfile> and appropriate security policies <https://docs.oracle.com/en-us/iaas/Content/Identity/Concepts/policygetstarted.htm> before trying the examples.
