# Amazon AMI Builder
|
|
|
|
|
|
|
|
|
|
Packer is able to create Amazon AMIs. To achieve this, Packer comes with
|
|
|
|
|
multiple builders depending on the strategy you want to use to build the
|
|
|
|
|
AMI. Packer supports the following builders at the moment:
|
|
|
|
|
|
|
|
|
|
* [amazon-ebs](/docs/builders/amazon-ebs.html) - Create EBS-backed AMIs
|
|
|
|
|
by launching a source instance and re-packaging it into a new AMI after
|
|
|
|
|
provisioning. If in doubt, use this builder, which is the easiest to get
|
|
|
|
|
started with.
|
|
|
|
|
|
|
|
|
|
* [amazon-instance](/docs/builders/amazon-instance.html) - Create
|
|
|
|
|
instance-store AMIs by launching and provisioning a source instance, then
|
|
|
|
|
rebundling it and uploading it to S3.

|
|
|
* [amazon-chroot](/docs/builders/amazon-chroot.html) - Create EBS-backed AMIs
|
|
|
|
|
from an existing EC2 instance by mounting the root device and using a
|
|
|
|
|
[Chroot](http://en.wikipedia.org/wiki/Chroot) environment to provision
|
|
|
|
|
that device. This is an **advanced builder and should not be used by
|
|
|
|
|
newcomers**. However, it is also the fastest way to build an EBS-backed
|
|
|
|
|
AMI since no new EC2 instance needs to be launched.

<strong>Don't know which builder to use?</strong> If in doubt, use the
|
|
|
|
|
<a href="/docs/builders/amazon-ebs.html">amazon-ebs builder</a>. It is
|
|
|
|
|
much easier to use and Amazon generally recommends EBS-backed images nowadays.
