create

Description

Creates a new virtual cloud network (VCN). For more information, see VCNs and Subnets.

For the VCN, you specify a list of one or more IPv4 CIDR blocks that meet the following criteria:

  • The CIDR blocks must be valid. - They must not overlap with each other or with the on-premises network CIDR block. - The number of CIDR blocks does not exceed the limit of CIDR blocks allowed per VCN.

For a CIDR block, Oracle recommends that you use one of the private IP address ranges specified in RFC 1918 (10.0.0.0/8, 172.16/12, and 192.168/16). Example: 172.16.0.0/16. The CIDR blocks can range from /16 to /30.

For the purposes of access control, you must provide the OCID of the compartment where you want the VCN to reside. Consult an Oracle Cloud Infrastructure administrator in your organization if you’re not sure which compartment to use. Notice that the VCN doesn’t have to be in the same compartment as the subnets or other Networking Service components. For more information about compartments and access control, see Overview of the IAM Service. For information about OCIDs, see Resource Identifiers.

You may optionally specify a display name for the VCN, otherwise a default is provided. It does not have to be unique, and you can change it. Avoid entering confidential information.

You can also add a DNS label for the VCN, which is required if you want the instances to use the Interent and VCN Resolver option for DNS in the VCN. For more information, see DNS in Your Virtual Cloud Network.

The VCN automatically comes with a default route table, default security list, and default set of DHCP options. The OCID for each is returned in the response. You can’t delete these default objects, but you can change their contents (that is, change the route rules, security list rules, and so on).

The VCN and subnets you create are not accessible until you attach an internet gateway or set up an IPSec VPN or FastConnect. For more information, see Overview of the Networking Service.

Usage

oci network vcn create [OPTIONS]

Required Parameters

--compartment-id, -c [text]

The OCID of the compartment to contain the VCN.

Optional Parameters

--cidr-block [text]

Deprecated. Do not set this value. Use cidrBlocks instead. Example: 10.0.0.0/16

--cidr-blocks [complex type]

The list of one or more IPv4 CIDR blocks for the VCN that meet the following criteria: - The CIDR blocks must be valid. - They must not overlap with each other or with the on-premises network CIDR block. - The number of CIDR blocks must not exceed the limit of CIDR blocks allowed per VCN.

Important: Do not specify a value for cidrBlock. Use this parameter instead. 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.

--defined-tags [complex type]

Defined tags for this resource. Each key is predefined and scoped to a namespace. For more information, see Resource Tags.

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.

--display-name [text]

A user-friendly name. Does not have to be unique, and it’s changeable. Avoid entering confidential information.

--dns-label [text]

A DNS label for the VCN, used in conjunction with the VNIC’s hostname and subnet’s DNS label to form a fully qualified domain name (FQDN) for each VNIC within this subnet (for example, bminstance-1.subnet123.vcn1.oraclevcn.com). Not required to be unique, but it’s a best practice to set unique DNS labels for VCNs in your tenancy. Must be an alphanumeric string that begins with a letter. The value cannot be changed.

You must set this value if you want instances to be able to use hostnames to resolve other instances in the VCN. Otherwise the Internet and VCN Resolver will not work.

For more information, see DNS in Your Virtual Cloud Network.

Example:

vcn1
--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.

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

--is-ipv6-enabled [boolean]

Whether IPv6 is enabled for the VCN. Default is false. If enabled, Oracle will assign the VCN a IPv6 /56 CIDR block. For important details about IPv6 addressing in a VCN, see IPv6 Addresses.

Example:

true
--max-wait-seconds [integer]

The maximum time to wait for the resource to reach the lifecycle state defined by --wait-for-state. Defaults to 1200 seconds.

--wait-for-state [text]

This operation creates, modifies or deletes a resource that has a defined lifecycle state. Specify this option to perform the action and then wait until the resource reaches a given lifecycle state. Multiple states can be specified, returning on the first state. For example, --wait-for-state SUCCEEDED --wait-for-state FAILED would return on whichever lifecycle state is reached first. If timeout is reached, a return code of 2 is returned. For any other error, a return code of 1 is returned.

Accepted values are:

AVAILABLE, PROVISIONING, TERMINATED, TERMINATING, UPDATING
--wait-interval-seconds [integer]

Check every --wait-interval-seconds to see whether the resource to see if it has reached the lifecycle state defined by --wait-for-state. Defaults to 30 seconds.

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 and appropriate security policies before trying the examples.
