I know that AMI can be created from EBS snapshot on EC2 console.
I want to operate this AMI creation not on the AWS console but with the AWS CLI command.
The aws ec2 copy-image command does not have any EBS Snapshot option to specify. Is there any way to do this with CLI or calling APIs?
after I had the same problem and was looking for the simple example (because the documentation like linked in above is a little bit confused written) - and unfortunately could not find any, I post a simple example aws-cli call.
A real world example:
aws ec2 register-image --name "YOUR_DESCRIPTION" --region=eu-west-1 --description "AMI_from_snapshot_EBS" --block-device-mappings DeviceName="/dev/sda",Ebs={SnapshotId="snap-0070070007"} --root-device-name "/dev/sda1"
OUTPUT should be something like this:
{
"ImageId": "ami-0022d44252254fffff7"
}
From Creating an Amazon EBS-Backed Linux AMI - Amazon Elastic Compute Cloud:
To create an AMI from a snapshot using the command line
You can use one of the following commands. For more information about these command line interfaces, see Accessing Amazon EC2.
register-image (AWS CLI)
Register-EC2Image (AWS Tools for Windows PowerShell)
The register-image documentation page says:
You can also use
RegisterImageto create an Amazon EBS-backed Linux AMI from a snapshot of a root device volume.
