Amazon Components

The Amazon plugin is able to create Amazon AMIs through Packer. To achieve this, the plugin comes with multiple builders, data sources, and a post-processor to build the AMI depending on the strategy you want to use.

Builders:

  • amazon-ebs - Create EBS-backed AMIs by launching a source AMI 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 - Create instance-store AMIs by launching and provisioning a source instance, then rebundling it and uploading it to S3.
  • amazon-chroot - Create EBS-backed AMIs from an existing EC2 instance by mounting the root device and using a 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.
  • amazon-ebssurrogate - Create EBS -backed AMIs from scratch. Works similarly to the chroot builder but does not require running in AWS. This is an advanced builder and should not be used by newcomers.

Data sources:

  • amazon-ami - Filter and fetch an Amazon AMI to output all the AMI information.
  • amazon-secretsmanager - Retrieve information about a Secrets Manager secret version, including its secret value.
  • amazon-parameterstore - Retrieve information about a parameter in SSM.

Post-Processors

  • amazon-import - The Amazon Import post-processor takes an OVA artifact from various builders and imports it to an AMI available to Amazon Web Services EC2.
