HCP Packer Version Data Source

Type: hcp-packer-version

The HCP Packer Version Data Source retrieves information about HCP Packer Version from the HCP Packer Registry. This information can be used to query HCP for a source external identifier for various Packer builders.

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

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:

• bucket_name (string) - The bucket name in the HCP Packer Registry.

• channel_name (string) - The channel name in the given bucket to use for retrieving the version.

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

Output Fields:

• author_id (string) - Name of the author who created this version.

• bucket_name (string) - The name of the bucket that this version is associated with.

• status (string) - Current state of the version.

• created_at (string) - The date the version was created.

• fingerprint (string) - The fingerprint of the version; this is a unique identifier set by the Packer build that created this version.

• id (string) - The version ID. This is a ULID, which is a unique identifier similar to a UUID. It is created by the HCP Packer Registry when a version is first created, and is unique to this version.

• name (string) - The version name is created by the HCP Packer Registry once a version is "complete". Incomplete or failed versions currently default to having a name "v0".

• updated_at (string) - The date when this version was last updated.

• channel_id (string) - The ID of the channel used to query this version.
