hcp-packer-version

The hcp-packer-version dsata source retrieves information about an HCP Packer version from the HCP Packer registry. You can use the version information to query HCP for a source's external identifier so that you can use it in various Packer builders.

To get started with HCP Packer, refer to the HCP Packer documentation or try the Get Started with HCP Packer tutorials.

Packer prints 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 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 HCP Packer Version, which can then be accessed as a variable.

data "hcp-packer-version" "hardened-source" {
  bucket_name  = "hardened-ubuntu-16-04"
  channel_name = "dev"
}

Full Example

This data source can be used in conjunction with the hcp-packer-artifact data source to retrieve an artifact identifier. 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.

# 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-version/Config-required.mdx'

There are currently no optional fields for this datasource, though we intend to add filtering fields in the future.
