name : create-capacity-reservation.rst **Example 1: To create a Capacity Reservation** The following ``create-capacity-reservation`` example creates a capacity reservation in the ``eu-west-1a`` Availability Zone, into which you can launch three ``t2.medium`` instances running a Linux/Unix operating system. By default, the capacity reservation is created with open instance matching criteria and no support for ephemeral storage, and it remains active until you manually cancel it. :: aws ec2 create-capacity-reservation \ --availability-zone eu-west-1a \ --instance-type t2.medium \ --instance-platform Linux/UNIX \ --instance-count 3 Output:: { "CapacityReservation": { "CapacityReservationId": "cr-1234abcd56EXAMPLE ", "EndDateType": "unlimited", "AvailabilityZone": "eu-west-1a", "InstanceMatchCriteria": "open", "EphemeralStorage": false, "CreateDate": "2019-08-16T09:27:35.000Z", "AvailableInstanceCount": 3, "InstancePlatform": "Linux/UNIX", "TotalInstanceCount": 3, "State": "active", "Tenancy": "default", "EbsOptimized": false, "InstanceType": "t2.medium" } } **Example 2: To create a Capacity Reservation that automatically ends at a specified date/time** The following ``create-capacity-reservation`` example creates a capacity reservation in the ``eu-west-1a`` Availability Zone, into which you can launch three ``m5.large`` instances running a Linux/Unix operating system. This capacity reservation automatically ends on 08/31/2019 at 23:59:59. :: aws ec2 create-capacity-reservation \ --availability-zone eu-west-1a \ --instance-type m5.large \ --instance-platform Linux/UNIX \ --instance-count 3 \ --end-date-type limited \ --end-date 2019-08-31T23:59:59Z Output:: { "CapacityReservation": { "CapacityReservationId": "cr-1234abcd56EXAMPLE ", "EndDateType": "limited", "AvailabilityZone": "eu-west-1a", "EndDate": "2019-08-31T23:59:59.000Z", "InstanceMatchCriteria": "open", "EphemeralStorage": false, "CreateDate": "2019-08-16T10:15:53.000Z", "AvailableInstanceCount": 3, "InstancePlatform": "Linux/UNIX", "TotalInstanceCount": 3, "State": "active", "Tenancy": "default", "EbsOptimized": false, "InstanceType": "m5.large" } } **Example 3: To create a Capacity Reservation that accepts only targeted instance launches** The following ``create-capacity-reservation`` example creates a capacity reservation that accepts only targeted instance launches. :: aws ec2 create-capacity-reservation \ --availability-zone eu-west-1a \ --instance-type m5.large \ --instance-platform Linux/UNIX \ --instance-count 3 \ --instance-match-criteria targeted Output:: { "CapacityReservation": { "CapacityReservationId": "cr-1234abcd56EXAMPLE ", "EndDateType": "unlimited", "AvailabilityZone": "eu-west-1a", "InstanceMatchCriteria": "targeted", "EphemeralStorage": false, "CreateDate": "2019-08-16T10:21:57.000Z", "AvailableInstanceCount": 3, "InstancePlatform": "Linux/UNIX", "TotalInstanceCount": 3, "State": "active", "Tenancy": "default", "EbsOptimized": false, "InstanceType": "m5.large" } } For more information, see `Create a Capacity Reservation <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/capacity-reservations-using.html>`__ in the *Amazon EC2 User Guide*.
