**Example 1: To describe a Spot Instance request** The following ``describe-spot-instance-requests`` example describes the specified Spot Instance request. :: aws ec2 describe-spot-instance-requests \ --spot-instance-request-ids sir-08b93456 Output:: { "SpotInstanceRequests": [ { "CreateTime": "2018-04-30T18:14:55.000Z", "InstanceId": "i-1234567890abcdef1", "LaunchSpecification": { "InstanceType": "t2.micro", "ImageId": "ami-003634241a8fcdec0", "KeyName": "my-key-pair", "SecurityGroups": [ { "GroupName": "default", "GroupId": "sg-e38f24a7" } ], "BlockDeviceMappings": [ { "DeviceName": "/dev/sda1", "Ebs": { "DeleteOnTermination": true, "SnapshotId": "snap-0e54a519c999adbbd", "VolumeSize": 8, "VolumeType": "standard", "Encrypted": false } } ], "NetworkInterfaces": [ { "DeleteOnTermination": true, "DeviceIndex": 0, "SubnetId": "subnet-049df61146c4d7901" } ], "Placement": { "AvailabilityZone": "us-east-2b", "Tenancy": "default" }, "Monitoring": { "Enabled": false } }, "LaunchedAvailabilityZone": "us-east-2b", "ProductDescription": "Linux/UNIX", "SpotInstanceRequestId": "sir-08b93456", "SpotPrice": "0.010000" "State": "active", "Status": { "Code": "fulfilled", "Message": "Your Spot request is fulfilled.", "UpdateTime": "2018-04-30T18:16:21.000Z" }, "Tags": [], "Type": "one-time", "InstanceInterruptionBehavior": "terminate" } ] } **Example 2: To describe Spot Instance requests based on filters** The following ``describe-spot-instance-requests`` example uses filters to scope the results to Spot Instance requests with the specified instance type in the specified Availability Zone. The example uses the ``--query`` parameter to display only the instance IDs. :: aws ec2 describe-spot-instance-requests \ --filters Name=launch.instance-type,Values=m3.medium Name=launched-availability-zone,Values=us-east-2a \ --query "SpotInstanceRequests[*].[InstanceId]" \ --output text Output:: i-057750d42936e468a i-001efd250faaa6ffa i-027552a73f021f3bd ...
