aws ec2 describe-instances
Describes the specified instances or all instances. If you specify instance IDs, the output includes information for only the specified instances. If you specify filters, the output includes information for only those instances that meet the filter criteria. If you do not specify instance IDs or filters, the output includes information for all instances, which can affect performance. We recommend that you use pagination to ensure that the operation returns quickly and successfully. If you specify an instance ID that is not valid, an error is returned. If you specify an instance that you do not own, it is not included in the output. Recently terminated instances might appear in the returned results. This interval is usually less than one hour. If you describe instances in the rare case where an Availability Zone is experiencing a service disruption and you specify instance IDs that are in the affected zone, or do not specify any instance IDs at all, the call fails. If you describe instances and specify only instance IDs that are in an unaffected zone, the call works normally

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. root-device-name - The device name of the root device volume (for example, /dev/sda1). root-device-type - The type of the root device volume (ebs | instance-store). source-dest-check - Indicates whether the instance performs source/destination checking.

Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value. tag-key - The key of a tag assigned to the resource. Use this filter to find all resources that have a tag with a specific key, regardless of the tag value. 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 |
--instance-ids <list> [arg...] | The instance IDs. Default: Describes all your instances |
--dry-run | 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 |
--no-dry-run | 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. To retrieve the remaining results, make another call with the returned NextToken value. This value can be between 5 and 1000. You cannot specify this parameter and the instance IDs parameter in the same call |
--next-token <string> | The token to request the next page of results |
--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 |
--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``. If provided with the value ``output``, it validates the command inputs and returns a sample output JSON for that command |
