執行個體請求。如果您的帳戶僅支援 EC2-VPC，Amazon EC2 會在指定之可用區域的預設子網路中啟動執行個體。如果您的帳戶支援 EC2-Classic，Amazon EC2 會在指定之可用區域中啟動 EC2-Classic 中的執行個體。 命令： ``` aws ec2 request-spot-instances --spot-price "0.03" --instance-count 5 --type "one-time" --launch-specification file://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" } } ``` 輸出： ``` { "SpotInstanceRequests": [ { "Status": { "UpdateTime": "2014-03-25T20:54:21.000Z", "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", "KeyName": "my-key-pair", "SecurityGroups": [ { "GroupName": "my-security-group", "GroupId": "sg-1a2b3c4d" } ], "Monitoring": { "Enabled": false }, "IamInstanceProfile": { "Arn": "arn:aws:iam::123456789012:instance-profile/my-iam-role" }, "InstanceType": "m3.medium" }, "Type": "one-time", "CreateTime": "2014-03-25T20:54:20.000Z", "SpotPrice": "0.050000" }, ... ] } ``` 此範例命令會為指定子網路中的五個執行個體，建立一次性 Spot 執行個體請求。Amazon EC2 會在指定子網中啟動執行個體。如果 VPC 為非預設 VPC，則執行個體預設不會接收公有 IP 位址。 命令： ``` aws ec2 request-spot-instances --spot-price "0.050" --instance-count 5 --type "one-time" --launch-specification file://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" } } ``` 輸出： ``` { "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" }, ... ] } ``` 此範例會將公有 IP 位址，指派給您在非預設 VPC 中啟動的 Spot 執行個體。請注意，您在指定網路介面時，必須加入使用網路介面的子網路 ID 和安全群組 ID。 命令： ``` aws ec2 request-spot-instances --spot-price "0.050" --instance-count 1 --type "one-time" --launch-specification file://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" } } ``` + 如需 API

**Tools for PowerShell V4** **範例 1：此範例會請求指定子網路中的一次性 Spot 執行個體。請注意，必須為包含指定子網路的 VPC 建立安全群組，而且必須使用網路介面透過 ID 指定。指定網路介面時，必須納入使用網路介面的子網路 ID。** ``` $n = New-Object
