**To create an AMI from an Amazon EBS-backed instance** This example creates an AMI from the specified instance. Command:: aws ec2 create-image --instance-id i-1234567890abcdef0 --name "My server" --description "An AMI for my server" Output:: { "ImageId": "ami-5731123e" } This example creates an AMI and sets the --no-reboot parameter, so that the instance is not rebooted before the image is created. Command:: aws ec2 create-image --instance-id i-0b09a25c58929de26 --name "My server" --no-reboot Output:: { "ImageId": "ami-1a2b3c4d" } **To create an AMI using a block device mapping** Add the following parameter to your ``create-image`` command to add an Amazon EBS volume with the device name ``/dev/sdh`` and a volume size of 100:: --block-device-mappings "[{\"DeviceName\": \"/dev/sdh\",\"Ebs\":{\"VolumeSize\":100}}]" Add the following parameter to your ``create-image`` command to add ``ephemeral1`` as an instance store volume with the device name ``/dev/sdc``:: --block-device-mappings "[{\"DeviceName\": \"/dev/sdc\",\"VirtualName\":\"ephemeral1\"}]" Add the following parameter to your ``create-image`` command to omit a device included on the instance (for example, ``/dev/sdf``):: --block-device-mappings "[{\"DeviceName\": \"/dev/sdf\",\"NoDevice\":\"\"}]"
