<!-- Code generated from the comments of the AMIConfig struct in builder/amazon/common/ami_config.go; DO NOT EDIT MANUALLY -->
- `ami_description` (string) - The description to set for the resulting
AMI(s). By default this description is empty. This is a
[template engine](/docs/templates/engine), see [Build template
data](#build-template-data) for more information.
- `ami_virtualization_type` (string) - The type of virtualization for the AMI
you are building. This option is required to register HVM images. Can be
paravirtual (default) or hvm.
- `ami_users` ([]string) - A list of account IDs that have access to
launch the resulting AMI(s). By default no additional users other than the
user creating the AMI has permissions to launch it.
- `ami_groups` ([]string) - A list of groups that have access to
launch the resulting AMI(s). By default no groups have permission to launch
the AMI. all will make the AMI publicly accessible.
- `ami_product_codes` ([]string) - A list of product codes to
associate with the AMI. By default no product codes are associated with the
AMI.
- `ami_regions` ([]string) - A list of regions to copy the AMI to.
Tags and attributes are copied along with the AMI. AMI copying takes time
depending on the size of the AMI, but will generally take many minutes.
- `skip_region_validation` (bool) - Set to true if you want to skip
validation of the ami_regions configuration option. Default false.
- `tags` (map[string]string) - Key/value pair tags applied to the AMI. This is a [template
engine](/docs/templates/engine), see [Build template
data](#build-template-data) for more information.
- `tag` ([]{key string, value string}) - Same as [`tags`](#tags) but defined as a singular repeatable block
containing a `key` and a `value` field. In HCL2 mode the
[`dynamic_block`](/docs/configuration/from-1.5/expressions#dynamic-blocks)
will allow you to create those programatically.
- `ena_support` (boolean) - Enable enhanced networking (ENA but not SriovNetSupport) on
HVM-compatible AMIs. If set, add `ec2:ModifyInstanceAttribute` to your
AWS IAM policy.
Note: you must make sure enhanced networking is enabled on your
instance. See [Amazon's documentation on enabling enhanced
networking](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.html#enabling_enhanced_networking).
- `sriov_support` (bool) - Enable enhanced networking (SriovNetSupport but not ENA) on
HVM-compatible AMIs. If true, add `ec2:ModifyInstanceAttribute` to your
AWS IAM policy. Note: you must make sure enhanced networking is enabled
on your instance. See [Amazon's documentation on enabling enhanced
networking](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.html#enabling_enhanced_networking).
Default `false`.
- `force_deregister` (bool) - Force Packer to first deregister an existing
AMI if one with the same name already exists. Default false.
- `force_delete_snapshot` (bool) - Force Packer to delete snapshots
associated with AMIs, which have been deregistered by force_deregister.
Default false.
- `encrypt_boot` (boolean) - Whether or not to encrypt the resulting AMI when
copying a provisioned instance to an AMI. By default, Packer will keep the
encryption setting to what it was in the source image. Setting false will
result in an unencrypted image, and true will result in an encrypted one.
If you have used the `launch_block_device_mappings` to set an encryption
key and that key is the same as the one you want the image encrypted with
at the end, then you don't need to set this field; leaving it empty will
prevent an unnecessary extra copy step and save you some time.
- `kms_key_id` (string) - ID, alias or ARN of the KMS key to use for boot volume encryption. This
only applies to the main `region`, other regions where the AMI will be
copied will be encrypted by the default EBS KMS key. For valid formats
see *KmsKeyId* in the [AWS API docs -
CopyImage](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CopyImage.html).
This field is validated by Packer, when using an alias, you will have to
prefix `kms_key_id` with `alias/`.
- `region_kms_key_ids` (map[string]string) - regions to copy the ami to, along with the custom kms key id (alias or
arn) to use for encryption for that region. Keys must match the regions
provided in `ami_regions`. If you just want to encrypt using a default
ID, you can stick with `kms_key_id` and `ami_regions`. If you want a
region to be encrypted with that region's default key ID, you can use an
empty string `""` instead of a key id in this map. (e.g. `"us-east-1":
""`) However, you cannot use default key IDs if you are using this in
conjunction with `snapshot_users` -- in that situation you must use
custom keys. For valid formats see *KmsKeyId* in the [AWS API docs -
CopyImage](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CopyImage.html).
This option supercedes the `kms_key_id` option -- if you set both, and
they are different, Packer will respect the value in
`region_kms_key_ids` for your build region and silently disregard the
value provided in `kms_key_id`.
- `skip_save_build_region` (bool) - If true, Packer will not check whether an AMI with the `ami_name` exists
in the region it is building in. It will use an intermediary AMI name,
which it will not convert to an AMI in the build region. It will copy
the intermediary AMI into any regions provided in `ami_regions`, then
delete the intermediary AMI. Default `false`.
- `snapshot_tags` (map[string]string) - Key/value pair tags to apply to snapshot. They will override AMI tags if
already applied to snapshot. This is a [template
engine](/docs/templates/engine), see [Build template
data](#build-template-data) for more information.
- `snapshot_tag` ([]{key string, value string}) - Same as [`snapshot_tags`](#snapshot_tags) but defined as a singular
repeatable block containing a `key` and a `value` field. In HCL2 mode the
[`dynamic_block`](/docs/configuration/from-1.5/expressions#dynamic-blocks)
will allow you to create those programatically.
- `snapshot_users` ([]string) - A list of account IDs that have
access to create volumes from the snapshot(s). By default no additional
users other than the user creating the AMI has permissions to create
volumes from the backing snapshot(s).
- `snapshot_groups` ([]string) - A list of groups that have access to
create volumes from the snapshot(s). By default no groups have permission
to create volumes from the snapshot(s). all will make the snapshot
publicly accessible.
