- `bucket_name` (string) - The name of the bucket your artifact is in. - `channel_name` (string) - The name of the channel to use when retrieving your artifact. Either `channel_name` or `version_fingerprint` MUST be set. If using several artifacts from a single version, you may prefer sourcing a version first, and referencing it for subsequent uses, as every `hcp_packer_artifact` with the channel set will generate a potentially billable HCP Packer request, but if several `hcp_packer_artifact`s use a shared `hcp_packer_version` that will only generate one potentially billable request. - `version_fingerprint` (string) - The fingerprint of the version to use when retrieving your artifact. Either this or `channel_name` MUST be set. Mutually exclusive with `channel_name` - `platform` (string) - The name of the platform that your artifact is for. For example, "aws", "azure", or "gce". - `region` (string) - The name of the region your artifact is in. For example "us-east-1".
