describe-scheduled-instance-availability

Description

Finds available schedules that meet the specified criteria.

You can search for an available schedule no more than 3 months in advance. You must meet the minimum required duration of 1,200 hours per year. For example, the minimum daily schedule is 4 hours, the minimum weekly schedule is 24 hours, and the minimum monthly schedule is 100 hours.

After you find a schedule that meets your needs, call PurchaseScheduledInstances to purchase Scheduled Instances with that schedule.

See ‘aws help’ for descriptions of global parameters.

describe-scheduled-instance-availability 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: ScheduledInstanceAvailabilitySet

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 .

--filters (list)

The filters.

  • availability-zone - The Availability Zone (for example, us-west-2a ).

  • instance-type - The instance type (for example, c4.large ).

  • network-platform - The network platform (EC2-Classic or EC2-VPC ).

  • platform - The platform (Linux/UNIX or Windows ).

(structure)

A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs. The filters supported by a describe operation are documented with the describe operation. For example:

  • DescribeAvailabilityZones

  • DescribeImages

  • DescribeInstances

  • DescribeKeyPairs

  • DescribeSecurityGroups

  • DescribeSnapshots

  • DescribeSubnets

  • DescribeTags

  • DescribeVolumes

  • DescribeVpcs

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

The filter values. Filter values are case-sensitive.

(string)

Shorthand Syntax:

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

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--first-slot-start-time-range (structure)

The time period for the first schedule to start.

EarliestTime -> (timestamp)

The earliest date and time, in UTC, for the Scheduled Instance to start.

LatestTime -> (timestamp)

The latest date and time, in UTC, for the Scheduled Instance to start. This value must be later than or equal to the earliest date and at most three months in the future.

Shorthand Syntax:

EarliestTime=timestamp,LatestTime=timestamp

JSON Syntax:

{
  "EarliestTime": timestamp,
  "LatestTime": timestamp
}

--max-slot-duration-in-hours (integer)

The maximum available duration, in hours. This value must be greater than MinSlotDurationInHours and less than 1,720.

--min-slot-duration-in-hours (integer)

The minimum available duration, in hours. The minimum required duration is 1,200 hours per year. For example, the minimum daily schedule is 4 hours, the minimum weekly schedule is 24 hours, and the minimum monthly schedule is 100 hours.

--recurrence (structure)

The schedule recurrence.

Frequency -> (string)

The frequency (Daily , Weekly , or Monthly ).

Interval -> (integer)

The interval quantity. The interval unit depends on the value of Frequency . For example, every 2 weeks or every 2 months.

OccurrenceDays -> (list)

The days. For a monthly schedule, this is one or more days of the month (1-31). For a weekly schedule, this is one or more days of the week (1-7, where 1 is Sunday). You can’t specify this value with a daily schedule. If the occurrence is relative to the end of the month, you can specify only a single day.

(integer)

OccurrenceRelativeToEnd -> (boolean)

Indicates whether the occurrence is relative to the end of the specified week or month. You can’t specify this value with a daily schedule.

OccurrenceUnit -> (string)

The unit for OccurrenceDays (DayOfWeek or DayOfMonth ). This value is required for a monthly schedule. You can’t specify DayOfWeek with a weekly schedule. You can’t specify this value with a daily schedule.

Shorthand Syntax:

Frequency=string,Interval=integer,OccurrenceDays=integer,integer,OccurrenceRelativeToEnd=boolean,OccurrenceUnit=string

JSON Syntax:

{
  "Frequency": "string",
  "Interval": integer,
  "OccurrenceDays": [integer, ...],
  "OccurrenceRelativeToEnd": true|false,
  "OccurrenceUnit": "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.

--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 .

--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 .

--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. 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 describe an available schedule

This example describes a schedule that occurs every week on Sunday, starting on the specified date.

Command:

aws ec2 describe-scheduled-instance-availability --recurrence Frequency=Weekly,Interval=1,OccurrenceDays=[1] --first-slot-start-time-range EarliestTime=2016-01-31T00:00:00Z,LatestTime=2016-01-31T04:00:00Z

Output:

{
  "ScheduledInstanceAvailabilitySet": [
    {
        "AvailabilityZone": "us-west-2b",
        "TotalScheduledInstanceHours": 1219,
        "PurchaseToken": "eyJ2IjoiMSIsInMiOjEsImMiOi...",
        "MinTermDurationInDays": 366,
        "AvailableInstanceCount": 20,
        "Recurrence": {
            "OccurrenceDaySet": [
                1
            ],
            "Interval": 1,
            "Frequency": "Weekly",
            "OccurrenceRelativeToEnd": false
        },
        "Platform": "Linux/UNIX",
        "FirstSlotStartTime": "2016-01-31T00:00:00Z",
        "MaxTermDurationInDays": 366,
        "SlotDurationInHours": 23,
        "NetworkPlatform": "EC2-VPC",
        "InstanceType": "c4.large",
        "HourlyPrice": "0.095"
    },
    ...
  ]
}

To narrow the results, you can add filters that specify the operating system, network, and instance type.

Command:

–filters Name=platform,Values=Linux/UNIX Name=network-platform,Values=EC2-VPC Name=instance-type,Values=c4.large
