# HCP Packer Artifact Data Source

Type: `hcp-packer-artifact`

The `HCP Packer Artifact` Data Source retrieves information about an
artifact from the HCP Packer Registry. This information can be used to
provide a source artifact to various Packer builders.

To get started with HCP Packer, refer to the [HCP Packer documentation](/hcp/docs/packer) or try
the [Get Started with HCP Packer tutorials](/packer/tutorials/hcp-get-started).

~> **Note:** You will receive an error if you try to reference metadata from a deactivated or deleted registry.
An administrator can manually deactivate or delete a registry, and HCP Packer automatically deactivates registries
with billing issues. Contact [HashiCorp Support](https://support.hashicorp.com/) with questions.

## Revoked Versions

If an HCP Packer Version is revoked, the `hcp-packer-version` data source will fail and Packer won't proceed with
the build. Building new artifacts from a revoked artifact is not compliant.
Versions that are scheduled to be revoked will still be considered valid until the revocation date.

## Basic Example

Below is a fully functioning example. It stores information about an image artifact,
which can then be parsed and accessed as a variable.

```hcl
data "hcp-packer-artifact" "example" {
  bucket_name         = "hardened-ubuntu-16-04"
  version_fingerprint = "${data.hcp-packer-version.hardened-source.fingerprint}"
  platform            = "aws"
  region              = "us-east-1"
}
```

## Full Example

This data source can be used in conjunction with the hcp-packer-version
data source to retrieve a version fingerprint using a channel. You provide the version fingerprint and channel
name to the version data source, then use the version source inside the
artifact data source, then use the artifact data source inside your source block.

```hcl
# Retrieves information about the HCP Packer Version; a "version" can be
# thought of as all the metadata created by a single call of `packer build`.
data "hcp-packer-version" "hardened-source" {
  bucket_name  = "hardened-ubuntu-16-04"
  channel_name = "dev"
}

# Retrieves information about the HCP Packer Artifact; an artifact can be thought
# of as all the metadata (including the artifact names) created by a single
# "source" builder; this can include multiple artifacts so we provide a
# region to disambiguate.
data "hcp-packer-artifact" "example" {
  bucket_name         = "hardened-ubuntu-16-04"
  version_fingerprint = data.hcp-packer-version.hardened-source.fingerprint
  platform            = "aws"
  region              = "us-east-1"
}

# This source uses the output from a previous Packer build. By using the
# HCP Packer Registry in this way, you can easily create build pipelines where
# a single base artifact can be customized in multiple secondary layers.
source "amazon-ebs" "packer-secondary" {
  source_ami       = data.hcp-packer-artifact.example.external_identifier
  ...
}
```

## Configuration Reference

Configuration options are organized below into two categories: required and
optional. Within each category, the available options are alphabetized and
described.

### Required:

@include 'datasource/hcp-packer-artifact/Config-required.mdx'

### Optional:

~> **Note:** This data source only returns the first found artifact's metadata filtered by the given options,
from the returned list of artifacts associated with the specified version. Therefore, if multiple artifacts exist
in the same region, it will only pick one of them. In this case, you can filter artifact by a source build name
(Ex: `amazon-ebs.example`) using the `component_type` option.

@include 'datasource/hcp-packer-artifact/Config-not-required.mdx'

### Output Fields:

@include 'datasource/hcp-packer-artifact/DatasourceOutput.mdx'
