[ec2-user@ip-10-219-14-8 ~]$ aws ec2 describe-instances helpDESCRIBE-INSTANCES() DESCRIBE-INSTANCES()NAME describe-instances -DESCRIPTION Describes the specified instances or all of AWS account's instances. If you specify one or more instance IDs, Amazon EC2 returns information for those instances. If you do not specify instance IDs, Amazon EC2 returns information for all relevant instances. 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 returned results. 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. See also: AWS API Documentation See 'aws help' for descriptions of global parameters. describe-instances 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: ReservationsSYNOPSIS describe-instances [--filters ] [--instance-ids ] [--dry-run | --no-dry-run] [--cli-input-json ] [--starting-token ] [--page-size ] [--max-items ] [--generate-cli-skeleton ]OPTIONS --filters (list) The filters. o affinity - The affinity setting for an instance running on a Dedi- cated Host (default | host ). o architecture - The instance architecture (i386 | x86_64 | arm64 ). o availability-zone - The Availability Zone of the instance. o block-device-mapping.attach-time - The attach time for an EBS vol- ume mapped to the instance, for example, 2010-09-15T17:15:20.000Z . o block-device-mapping.delete-on-termination - A Boolean that indi- cates whether the EBS volume is deleted on instance termination. o block-device-mapping.device-name - The device name specified in the block device mapping (for example, /dev/sdh or xvdh ). o block-device-mapping.status - The status for the EBS volume (attaching | attached | detaching | detached ). o block-device-mapping.volume-id - The volume ID of the EBS volume. o client-token - The idempotency token you provided when you launched the instance. o dns-name - The public DNS name of the instance. o group-id - The ID of the security group for the instance.

Syntax: "string" "string" ... --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 DryRun- Operation . Otherwise, it is UnauthorizedOperation . --cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --gen- erate-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 sub- sequent 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. See 'aws help' for descriptions of global parameters.EXAMPLES Example 1: To describe an Amazon EC2 instance The following describe-instances example displays details about the specified instance. aws ec2 describe-instances --instance-ids i-1234567890abcdef0 Example 2: To describe instances based on instance type The following describe-instances example displays details about only instances of the specified type. aws ec2 describe-instances --filters Name=instance-type,Values=m5.large Example 3: To describe instances based on tags The following describe-instances example displays details about only those instances that have a tag with the specified tag key (Owner), regardless of the tag value. aws ec2 describe-instances --filters "Name=tag-key,Values=Owner" The following describe-instances example displays details about only those instances that have a tag with the specified tag value (my-team), regardless of the tag key. aws ec2 describe-instances --filters "Name=tag-value,Values=my-team" The following describe-instances example displays details about only those instances that have the specified tag (Owner=my-team). aws ec2 describe-instances --filters "Name=tag:Owner,Values=my-team" Example 4: To filter the results based on multiple conditions The following describe-instances example displays details about all instances with the specified type that are also in the specified Avail- ability Zone. aws ec2 describe-instances \ --filters Name=instance-type,Values=t2.micro,t3.micro Name=availability-zone,Values=us-east-2c The following describe-instances example uses a JSON input file to per- form the same filtering as the previous example.

MetadataOptions -> (structure) The metadata options for the instance. State -> (string) The state of the metadata option changes. pending - The metadata options are being updated and the instance is not ready to process metadata traffic with the new selec- tion. applied - The metadata options have been suc- cessfully applied on the instance. HttpTokens -> (string) The state of token usage for your instance meta- data requests. If the parameter is not specified in the request, the default state is optional . If the state is optional , you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role creden- tials are returned. If the state is required , you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credential always returns the version 2.0 creden- tials; the version 1.0 credentials are not avail- able. HttpPutResponseHopLimit -> (integer) The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel. Default: 1 Possible values: Integers from 1 to 64 HttpEndpoint -> (string) This parameter enables or disables the HTTP meta- data endpoint on your instances. If the parameter is not specified, the default state is enabled . NOTE: If you specify a value of disabled , you will not be able to access your instance metadata. OwnerId -> (string) The ID of the AWS account that owns the reservation. RequesterId -> (string) The ID of the requester that launched the instances on your behalf (for example, AWS Management Console or Auto Scaling). ReservationId -> (string) The ID of the reservation. NextToken -> (string) The token to use to retrieve the next page of results. This value is null when there are no more results to return. DESCRIBE-INSTANCES()
