## 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](https://docs.edgeless.systems/constellation/overview/clouds) that Constellation supports.
