describe-rules

Description

Describes the specified rules or the rules for the specified listener. You must specify either a listener or one or more rules.

See also: AWS API Documentation

describe-rules is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Rules

Options

--listener-arn (string)

The Amazon Resource Name (ARN) of the listener.

--rule-arns (list)

The Amazon Resource Names (ARN) of the rules.

(string)

Syntax:

"string" "string" ...

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

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. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--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.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To describe a rule

Output

Rules -> (list)

Information about the rules.

(structure)

Information about a rule.

RuleArn -> (string)

The Amazon Resource Name (ARN) of the rule.

Priority -> (string)

The priority.

Conditions -> (list)

The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .

(structure)

Information about a condition for a rule.

Each rule can optionally include up to one of each of the following conditions: http-request-method , host-header , path-pattern , and source-ip . Each rule can also optionally include one or more of each of the following conditions: http-header and query-string . Note that the value for a condition can't be empty.

For more information, see Quotas for your Application Load Balancers .

Field -> (string)

The field in the HTTP request. The following are the possible values:

  • http-header
  • http-request-method
  • host-header
  • path-pattern
  • query-string
  • source-ip

Values -> (list)

The condition value. Specify only when Field is host-header or path-pattern . Alternatively, to specify multiple host names or multiple path patterns, use HostHeaderConfig or PathPatternConfig .

If Field is host-header and you are not using HostHeaderConfig , you can specify a single host name (for example, my.example.com) in Values . A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.

  • A-Z, a-z, 0-9
    • .
    • (matches 0 or more characters)
  • ? (matches exactly 1 character)

If Field is path-pattern and you are not using PathPatternConfig , you can specify a single path pattern (for example, /img/*) in Values . A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.

  • A-Z, a-z, 0-9
  • _ - . $ / ~ " ' @ : +
  • & (using &amp;)
    • (matches 0 or more characters)
  • ? (matches exactly 1 character)

(string)

HostHeaderConfig -> (structure)

Information for a host header condition. Specify only when Field is host-header .

Values -> (list)

The host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.

(string)

PathPatternConfig -> (structure)

Information for a path pattern condition. Specify only when Field is path-pattern .

Values -> (list)

The path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .

(string)

HttpHeaderConfig -> (structure)

Information for an HTTP header condition. Specify only when Field is http-header .

HttpHeaderName -> (string)

The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.

You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

Values -> (list)

The strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).

If the same header appears multiple times in the request, we search them in order until a match is found.

If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.

(string)

QueryStringConfig -> (structure)

Information for a query string condition. Specify only when Field is query-string .

Values -> (list)

The key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.

If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.

(structure)

Information about a key/value pair.

Key -> (string)

The key. You can omit the key.

Value -> (string)

The value.

HttpRequestMethodConfig -> (structure)

Information for an HTTP method condition. Specify only when Field is http-request-method .

Values -> (list)

The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.

If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.

(string)

SourceIpConfig -> (structure)

Information for a source IP condition. Specify only when Field is source-ip .

Values -> (list)

The source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.

If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .

The total number of values must be less than, or equal to five.

(string)

Actions -> (list)
