»HCP Packer Image Data Source

Type: hcp-packer-image

The HCP Packer Image Data Source retrieves information about an image from the HCP Packer registry. This information can be used to provide a source image to various Packer builders.

»Basic Example

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

data "hcp-packer-image" "example" {
  bucket_name = "hardened-ubuntu-16-04"
  iteration_id = "${data.hcp-packer-iteration.hardened-source.id}"
  cloud_provider = "aws"
  region = "us-east-1"
}

data "hcp-packer-image" "example" {  bucket_name = "hardened-ubuntu-16-04"  iteration_id = "${data.hcp-packer-iteration.hardened-source.id}"  cloud_provider = "aws"  region = "us-east-1"}

»Full Example

This data source can be used in conjunction with the hcp-packer-iteration data source to retrieve an image ID using a channel. You provide the channel name to the iteration data source, then use the iteration source in the image data source, then use the image data source inside your source block.

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

# Retrieves information about the HCP Packer "image"; an image can be thought
# of as all the metadata (including the artifact names) created by a single
# "source" builder; this can include multiple images so we provide a cloud
# region to disambiguate.
data "hcp-packer-image" "foo" {
  bucket_name = "hardened-ubuntu-16-04"
  iteration_id = data.hcp-packer-iteration.hardened-source.id
  cloud_provider = "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 image can be customized in multiple secondary layers.
source "amazon-ebs" "packer-secondary" {
  source_ami       = data.hcp-packer-image.foo.id
  # ...
}

# Retrieves information about the HCP Packer "iteration"; an "iteration" can be# thought of as all the metadata created by a single call of `packer build`.data "hcp-packer-iteration" "hardened-source" {  bucket_name = "hardened-ubuntu-16-04"  channel = "packer-test"}
# Retrieves information about the HCP Packer "image"; an image can be thought# of as all the metadata (including the artifact names) created by a single# "source" builder; this can include multiple images so we provide a cloud# region to disambiguate.data "hcp-packer-image" "foo" {  bucket_name = "hardened-ubuntu-16-04"  iteration_id = data.hcp-packer-iteration.hardened-source.id  cloud_provider = "aws"  region = "us-east-1"}
# This source uses the output from a previous Packer build.

»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 name of the bucket your image is in.

• iteration_id (string) - The name of the iteration Id to use when retrieving your image

• cloud_provider (string) - The name of the cloud provider that your image is for. For example, "aws" or "gce".

• region (string) - The name of the cloud region your image is in. For example "us-east-1".

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

»Output Fields:

• cloud_provider (string) - The name of the cloud provider that the image exists in. For example, "aws", "azure", or "gce".

• component_type (string) - The specific Packer builder or post-processor used to create the image.

• created_at (string) - The date and time at which the image was created.

• build_id (string) - The id of the build that created the image. This is a ULID, which is a unique identifier similar to a UUID. It is created by the HCP Packer Registry when an build is first created, and is unique to this build.

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

• packer_run_uuid (string) - The UUID associated with the Packer run that created this image.

• id (string) - ID or URL of the remote cloud image as given by a build.

• region (string) - The cloud region as given by packer build. eg. "ap-east-1". For locally managed clouds, this may map instead to a cluster, server or datastore.

• labels (map[string]string) - The key:value metadata labels associated with this build.
