Overview

Note:

When passing DescribeInstancesRequest as input to an Aws::Client method, you can use a vanilla Hash:

{
  filters: [
    {
      name: "String",
      values: ["String"],
    },
  ],
  instance_ids: ["String"],
  dry_run: false,
  max_results: 1,
  next_token: "String",
}

Contains the parameters for DescribeInstances.

Returns:

  • (Boolean)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response.

A reservation ID has a one-to-one relationship with an instance launch request, but can be associated with more than one instance if you launch multiple instances using the same launch request. For example, if you launch one instance, you get one reservation ID. If you launch ten instances using the same launch request, you also get one reservation ID.

  • state-reason-message - A message that describes the state change.

  • subnet-id - The ID of the subnet for the instance.

  • 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 the tag\'s key). 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.

  • tenancy - The tenancy of an instance (dedicated | default | host).

  • virtualization-type - The virtualization type of the instance (paravirtual | hvm).

  • vpc-id - The ID of the VPC that the instance is running in.

Returns:

  • (Array<String>)

    One or more instance IDs.

#max_resultsInteger

Returns:

  • (Integer)

    The maximum number of results to return in a single call.

#next_tokenString
