To request Spot Instances
This example command creates a one-time Spot Instance request for five instances in the specified Availability Zone. If your account supports EC2-VPC only, Amazon EC2 launches the instances in the default subnet of the specified Availability Zone. If your account supports EC2-Classic, Amazon EC2 launches the instances in EC2-Classic in the specified Availability Zone.
Command:
aws ec2 request-spot-instances --spot-price
"0.03"
--instance-count5
--type"one-time"
--launch-specificationfile://specification.json
Specification.json:
{ "ImageId": "ami-1a2b3c4d", "KeyName": "my-key-pair", "SecurityGroupIds": [ "sg-1a2b3c4d" ], "InstanceType": "m3.medium", "Placement": { "AvailabilityZone": "us-west-2a" }, "IamInstanceProfile": { "Arn": "arn:aws:iam::123456789012:instance-profile/my-iam-role" } }
Output:

This example command creates a one-time Spot Instance request for five instances in the specified subnet. Amazon EC2 launches the instances in the specified subnet. If the VPC is a nondefault VPC, the instances do not receive a public IP address by default.
Command:
aws ec2 request-spot-instances --spot-price
"0.050"
--instance-count5
--type"one-time"
--launch-specificationfile://specification.json
Specification.json:
{ "ImageId": "ami-1a2b3c4d", "SecurityGroupIds": [ "sg-1a2b3c4d" ], "InstanceType": "m3.medium", "SubnetId": "subnet-1a2b3c4d", "IamInstanceProfile": { "Arn": "arn:aws:iam::123456789012:instance-profile/my-iam-role" } }
Output:
{ "SpotInstanceRequests": [ { "Status": { "UpdateTime": "2014-03-25T22:21:58.000Z", "Code": "pending-evaluation", "Message": "Your Spot request has been submitted for review, and is pending evaluation." }, "ProductDescription": "Linux/UNIX", "SpotInstanceRequestId": "sir-df6f405d", "State": "open", "LaunchSpecification": { "Placement": { "AvailabilityZone": "us-west-2a" } "ImageId": "ami-1a2b3c4d" "SecurityGroups": [ { "GroupName": "my-security-group", "GroupID": "sg-1a2b3c4d" } ] "SubnetId": "subnet-1a2b3c4d", "Monitoring": { "Enabled": false }, "IamInstanceProfile": { "Arn": "arn:aws:iam::123456789012:instance-profile/my-iam-role" }, "InstanceType": "m3.medium", }, "Type": "one-time", "CreateTime": "2014-03-25T22:21:58.000Z", "SpotPrice": "0.050000" }, ... ] }
This example assigns a public IP address to the Spot Instances that you launch in a nondefault VPC. Note that when you specify a network interface, you must include the subnet ID and security group ID using the network interface.
Command:
aws ec2 request-spot-instances --spot-price
"0.050"
--instance-count1
--type"one-time"
--launch-specificationfile://specification.json
Specification.json:
{ "ImageId": "ami-1a2b3c4d", "KeyName": "my-key-pair", "InstanceType": "m3.medium", "NetworkInterfaces": [ { "DeviceIndex": 0, "SubnetId": "subnet-1a2b3c4d", "Groups": [ "sg-1a2b3c4d" ], "AssociatePublicIpAddress": true } ], "IamInstanceProfile": { "Arn": "arn:aws:iam::123456789012:instance-profile/my-iam-role" } }
