Synopsis

  describe-fleet-instances
[--dry-run | --no-dry-run]
[--max-results <value>]
[--next-token <value>]
--fleet-id <value>
[--filters <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 .

--max-results (integer)

The maximum number of results to return in a single call. Specify a value between 1 and 1000. The default value is 1000. To retrieve the remaining results, make another call with the returned NextToken value.

--next-token (string)

The token for the next set of results.

--fleet-id (string)

The ID of the EC2 Fleet.

--filters (list)

The filters.

• instance-type - The instance type.

(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.

If you specify multiple filters, the filters are joined with an AND , and the request returns only results that match all of the specified filters.

Name -> (string)

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

Values -> (list)

The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR , and the request returns all results that match any of the specified values.

(string)

Shorthand Syntax:

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

JSON Syntax:

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

See ‘aws help’ for descriptions of global parameters.

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 .

To describe the running instances for an EC2 Fleet

The following describe-fleet-instances example describes the running instances for the specified EC2 Fleet.

aws ec2 describe-fleet-instances \
    --fleet-id 12a34b55-67cd-8ef9-ba9b-9208dEXAMPLE

Output:

{
    "ActiveInstances": [
        {
            "InstanceId": "i-090db02406cc3c2d6",
            "InstanceType": "t2.small",
            "SpotInstanceRequestId": "sir-a43gtpfk",
            "InstanceHealth": "healthy"
        },
        {
            "InstanceId": "i-083a1c446e66085d2",

Output

ActiveInstances -> (list)

The running instances. This list is refreshed periodically and might be out of date.

(structure)

Describes a running instance in a Spot Fleet.

InstanceId -> (string)

The ID of the instance.

InstanceType -> (string)

The instance type.

SpotInstanceRequestId -> (string)
