[ec2-beta] ec2 concepts and understanding

[Thomas Butter]

Hi Jason,

from a running instance you could do something similar to this:

sudo ec2-bundle-vol -d /mnt -k YOUR-EC2-PRIVATE-KEY-FILE -c YOUR-EC2- 
CERT-FILE -u YOUR-AWS-ACCOUNT-NUMBER-WITHOUT-DASHED -r i386 -p  
mynewimage

ec2-upload-bundle -b YOUR-TARGET-S3-BUCKET -m /mnt/ 
mynewimage.manifest.xml -a YOUR-S3-ACCESSKEY -s YOUR-S3-SECRETKEY

You can then register the image at http://console.aws.amazon.com/  
using http://s3.amazonaws.com/YOUR-TARGET-S3-BUCKET/mynewimage.manifest.xml

Please refer to the EC2 documentation for details about these commands.

Regards,

Thomas
