Bundling an AMI is a three-step process:<br />
1. Create the image on the instance itself.<br />
2. Upload the image to Amazon S3.<br />
3. Register the AMI.<br />
Before proceeding, shut down your mongrel and PostgreSQL instances, just to<br />
make sure any open files are handled correctly. You must also copy your X.509<br />
keys, found in the Amazon Console, to /mnt on your server. Listing 12 shows the<br />
first two steps of bundling, which are done on the VM itself.<br />

The first command generates the bundle, specifying that /mnt is to be ignored and<br />
that the bundle will go in /mnt (the -e and -d options, respectively). The -k,<br />
--cert, and --user options point to your security credentials and AWS user ID,<br />
which are all found in the account settings of your AWS Management Console. The<br />
last option, -p, lets you name this AMI to differentiate it from others.<br />
The first command will run for about 10 minutes, depending on how full your root<br />
partition is. The second command uploads the bundle to Amazon S3. The -b option<br />
specifies a bucket name, which will be created if it doesn't exist already. The -m<br />
option points to the manifest file created in the last step. The last two options are<br />
your Amazon S3 credentials, which are found right next to your X.509 credentials in<br />
the AWS Management Console. Just remember that X.509 credentials are used for<br />
Amazon EC2 operations, while Amazon S3 uses text keys.<br />
Finally, run the command:<br />
