Map 'ec2-register snapshot' syntax onto 'register-image AMI 'syntax using awscli

Question

What is the correct syntax for mapping a snapshot onto an AMI using awscli? More explicitly, how do I map the old syntax 'ec2-register -s snap-9abc1234 --kernel 99abcdef' onto the new syntax 'aws ec2 --register-image' ?

Answer 1

It's the following:

aws ec2 register-image --kernel-id <your-kernel> --root-device-name /dev/sda1 --block-device-mappings [list in JSON shown below]

      [
        {
          "VirtualName": "string",
          "DeviceName": "string",
          "Ebs": {
            "SnapshotId": "string",
            "VolumeSize": integer,
            "DeleteOnTermination": true|false,
            "VolumeType": "standard"|"io1",
            "Iops": integer
          },
          "NoDevice": "string"
        }
        ...
      ]

You can run aws ec2 register-image help for help on the command.

Make sure you are using the awscli python package on not the aws package as that one is different (not the official one)
