describe-internet-gateways

Description

Describes one or more of your Internet gateways.

See also: AWS API Documentation

Synopsis

  describe-internet-gateways
[--filters <value>]
[--dry-run | --no-dry-run]
[--internet-gateway-ids <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--filters (list)

One or more filters.

  • attachment.state - The current state of the attachment between the gateway and the VPC (available ). Present only if a VPC is attached.
  • attachment.vpc-id - The ID of an attached VPC.
  • internet-gateway-id - The ID of the Internet gateway.
  • tag :key =*value* - The key/value combination of a tag assigned to the resource. Specify the key of the tag in the filter name and the value of the tag in the filter value. For example, for the tag Purpose=X, specify tag:Purpose for the filter name and X for the filter value.
  • tag-key - The key of a tag assigned to the resource. This filter is independent of the tag-value filter. For example, if you use both the filter "tag-key=Purpose" and the filter "tag-value=X", you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the tag :key =*value* filter.
  • tag-value - The value of a tag assigned to the resource. This filter is independent of the tag-key filter.

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

--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 .

--internet-gateway-ids (list)

One or more Internet gateway IDs.

Default: Describes all your Internet gateways.

Syntax:

"string" "string" ...

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
