create-network-acl¶

Description¶

Creates a network ACL in a VPC. Network ACLs provide an optional layer of security (in addition to security groups) for the instances in your VPC.

For more information, see Network ACLs in the Amazon Virtual Private Cloud User Guide .

Synopsis¶

  create-network-acl
[--dry-run | --no-dry-run]
--vpc-id <value>
[--tag-specifications <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--vpc-id (string)

The ID of the VPC.

--tag-specifications (list)

The tags to assign to the network ACL.

(structure)

The tags to apply to a resource when the resource is being created.

ResourceType -> (string)

The type of resource to tag on creation.

Tags -> (list)

The tags to apply to the resource.

(structure)

Describes a tag.

Key -> (string)

The key of the tag.

Constraints: Tag keys are case-sensitive and accept a maximum of 127 Unicode characters. May not begin with aws: .

Value -> (string)

The value of the tag.

Constraints: Tag values are case-sensitive and accept a maximum of 256 Unicode characters.

Shorthand Syntax:

ResourceType=string,Tags=[{Key=string,Value=string},{Key=string,Value=string}] ...

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To create a network ACL

This example creates a network ACL for the specified VPC.

Command:

aws ec2 create-network-acl --vpc-id vpc-a01106c2

Output:

{
    "NetworkAcl": {
        "Associations": [],
        "NetworkAclId": "acl-5fb85d36",
        "VpcId": "vpc-a01106c2",
        "Tags": [],
        "Entries": [
            {
                "CidrBlock": "0.0.0.0/0",
                "RuleNumber": 32767,
                "Protocol": "-1",
                "Egress": true,
                "RuleAction": "deny"
            },
            {
                "CidrBlock": "0.0.0.0/0",
                "RuleNumber": 32767,
                "Protocol": "-1",
                "Egress": false,
                "RuleAction": "deny"
            }
        ],
        "IsDefault": false
    }
}
