# Amazon Import Post-Processor

Type: `amazon-import`

The Packer Amazon Import post-processor takes an OVA artifact from various builder and imports it to an AMI available to Amazon Web Services EC2. 

\~&gt; This post-processor is for advanced users. It depends on specific IAM roles inside AWS and is best used with images that operate with the EC2 configuration model (eg, cloud-init for Linux systems). Please ensure you read the [prerequisites for import](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/VMImportPrerequisites.html) before using this post-processor.

## How Does it Work?

The import process operates making a temporary copy of the OVA to an S3 bucket, and calling an import task in EC2 on the OVA file. Once completed, an AMI is returned containing the converted virtual machine. The temporary OVA copy in S3 can be discarded after the import is complete.

The import process itself run by AWS includes modifications to the image uploaded, to allow it to boot and operate in the AWS EC2 environment. However, not all modifications required to make the machine run well in EC2 are performed. Take care around console output from the machine, as debugging can be very difficult without it. You may also want to include tools suitable for instances in EC2 such as cloud-init for Linux.

Further information about the import process can be found in AWS's [EC2 Import/Export Instance documentation](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instances_of_your_vm.html).

## Configuration

There are some configuration options available for the post-processor. They are
segmented below into three categories: required and optional parameters. 
Within each category, the available configuration keys are alphabetized.

Required:

-   `access_key` (string) - The access key used to communicate with AWS. [Learn
    how to set this.](/docs/builders/amazon.html#specifying-amazon-credentials)

-   `region` (string) - The name of the region, such as "us-east-1" in which to upload the OVA file to S3 and create the AMI. A list of valid regions can be obtained with AWS CLI tools or by consulting the AWS website.

-   `s3_bucket_name` (string) - The name of the S3 bucket where the OVA file will be copied to for import. This bucket must exist when the post-processor is run.

-   `secret_key` (string) - The secret key used to communicate with AWS. [Learn
    how to set this.](/docs/builders/amazon.html#specifying-amazon-credentials)

Optional:

-   `s3_key_name` (string) - The name of the key in `s3_bucket_name` where the OVA file will be copied to for import. If not specified, this will default to "packer-import-{{timestamp}}.ova". This key (ie, the uploaded OVA) will be removed after import, unless `skip_clean` is true.

-   `skip_clean` (boolean) - Whether we should skip removing the OVA file uploaded to S3 after the import process has completed. "true" means that we should leave it in the S3 bucket, "false" means to clean it out. Defaults to "false".

-   `ami_name` (string) - The name of the ami within the console. If not specified, this will default to something like `ami-import-sfwerwf`. Please note, specifying this option will result in a slightly longer execution time.

-   `tags` (object of key/value strings) - Tags applied to the created AMI and
    relevant snapshots.

## Basic Example

Here is a basic example. This assumes that the builder has produced an OVA artifact for us to work with, and IAM roles for import exist in the AWS account being imported into.

``` {.javascript}
{
  "type": "amazon-import",
  "access_key": "YOUR KEY HERE",
  "secret_key": "YOUR SECRET KEY HERE",
  "region": "us-east-1",
  "s3_bucket_name": "importbucket",
  "tags": {
    "Description": "packer amazon-import {{timestamp}}"
  }
}
```

-&gt; **Note:** Packer can also read the access key and secret access key from
environmental variables. See the configuration reference in the section above
for more information on what environmental variables Packer will look for.

This will take the OVA generated by a builder and upload it to S3. In this case, an existing bucket called "importbucket" in the "us-east-1" region will be where the copy is placed. The key name of the copy will be a default name generated by packer.

Once uploaded, the import process will start, creating an AMI in the "us-east-1" region with a "Description" tag applied to both the AMI and the snapshots associated with it. Note: the import process does not allow you to name the AMI, the name is automatically generated by AWS.

After tagging is completed, the OVA uploaded to S3 will be removed.
