constellation_attestation (Data Source)

Data source to fetch an attestation configuration for a given cloud service provider, attestation variant, and OS image.

Example Usage

data "constellation_image" "example" {} # Fill accordingly for the CSP

data "constellation_attestation" "test" {
  csp                 = "aws"
  attestation_variant = "aws-sev-snp"
  image               = data.constellation_image.example.image
}

Schema

Required

• attestation_variant (String) Attestation variant the image should work with. Can be one of:
  • aws-sev-snp
  • aws-nitro-tpm
  • azure-sev-snp
  • gcp-sev-es
• csp (String) CSP (Cloud Service Provider) to use. (e.g. azure) See the full list of CSPs that Constellation supports.
• image (Attributes) Constellation OS Image to use on the nodes. (see below for nested schema)

Optional

• insecure (Boolean) DON'T USE IN PRODUCTION Skip the signature verification when fetching measurements for the image.
• maa_url (String) For Azure only, the URL of the Microsoft Azure Attestation service

Read-Only

• attestation (Attributes) Attestation comprises the measurements and SEV-SNP specific parameters. (see below for nested schema)

Nested Schema for image

Required:

• reference (String) CSP-specific unique reference to the image. The format differs per CSP.
• short_path (String) CSP-agnostic short path to the image. The format is vX.Y.Z for release images and ref/$GIT_REF/stream/$STREAM/$SEMANTIC_VERSION for pre-release images.
• $GIT_REF is the git reference (i.e. branch name) the image was built on, e.g. main.
• $STREAM is the stream the image was built on, e.g. nightly.
• $SEMANTIC_VERSION is the semantic version of the image, e.g. vX.Y.Z or vX.Y.Z-pre....
• version (String) Semantic version of the image.
