How to create custom amazon AMI throught CLI Commands

Today, i am going to explain how you can create custom amazon ami to launch instance anytime later. This will have you clone of your server anytime you need. I am considering you are able to login your current running instance and you also have your private key and certificate downloaded on some location.

Upload your private key and certificate on the running instance.

scp -i path/of/yourkeypair.pem path/of/cert.pem /mnt
scp -i path/of/yourkeypair.pem path/of/pk.pem /mnt

Login to your instance and check if uploaded files are available in /mnt.

ec2-bundle-vol 
-d /mnt -k /mnt/pk.pem 
-c /mnt/cert.pem 
-u 673491274719 
-p name-of-ami

This will take some time and create the desired ami to be uploaded in the bucket. So you can use that later anytime you need. Now upload your bundle to amazon s3 storage.

ec2-upload-bundle 
-b <S3-bucket-name> 
-m /mnt/name-of-ami.manifest.xml 
-a <AWS-access-key-id> 
-s  <AWS-secret-access-key> 
--location US-EAST-1C

Note: Remember to upload to an S3 bucket in correct region. Also: if the bucket does not exit, it will be created for you. (I’ve used a European bucket as an example.) Now we need to register AMI. Do following< br />

ec2-register <bucket-name>/sampleimage.manifest.xml --region US-EAST-1C

It will return the new AMI ID (like ami-). That’s it you are done with your custom ami.
