describe-file-caches¶

Description¶

Returns the description of a specific Amazon File Cache resource, if a FileCacheIds value is provided for that cache. Otherwise, it returns descriptions of all caches owned by your Amazon Web Services account in the Amazon Web Services Region of the endpoint that you’re calling.

When retrieving all cache descriptions, you can optionally specify the MaxResults parameter to limit the number of descriptions in a response. If more cache descriptions remain, the operation returns a NextToken value in the response. In this case, send a later request with the NextToken request parameter set to the value of NextToken from the last response.

This operation is used in an iterative process to retrieve a list of your cache descriptions. DescribeFileCaches is called first without a NextToken value. Then the operation continues to be called with the NextToken parameter set to the value of the last NextToken value until a response has no NextToken .

When using this operation, keep the following in mind:

The implementation might return fewer than MaxResults cache descriptions while still including a NextToken value.
The order of caches returned in the response of one DescribeFileCaches call and the order of caches returned across the responses of a multicall iteration is unspecified.

Options¶

--file-cache-ids (list)

IDs of the caches whose descriptions you want to retrieve (String).

(string)

Syntax:

"string" "string" ...

--max-results (integer)

The maximum number of resources to return in the response. This value must be an integer greater than zero.

--next-token (string)

(Optional) Opaque pagination token returned from a previous operation (String). If present, this token indicates from what point you can continue processing the request, where the previous NextToken value left off.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

json
text
table
yaml
yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

on
off
auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

base64
raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.
