# constellation_attestation (Data Source)
The data source to fetch measurements from a configured cloud provider and image.
## Example Usage
```terraform
data "constellation_attestation" "test" {
csp = "aws"
attestation_variant = "aws-sev-snp"
image_version = "v2.13.0"
}
```
<!-- schema generated by tfplugindocs -->
## 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.
- `image_version` (String) The image version to use
### Optional
- `maa_url` (String) For Azure only, the URL of the Microsoft Azure Attestation service
### Read-Only
- `attestation` (Attributes) Only relevant for SEV-SNP. (see [below for nested schema](#nestedatt--attestation))
- `id` (String) The ID of the data source
- `measurements` (Attributes Map) (see [below for nested schema](#nestedatt--measurements))
<a id="nestedatt--attestation"></a>
### Nested Schema for `attestation`
Read-Only:
- `amd_root_key` (String)
- `azure_firmware_signer_config` (Attributes) (see [below for nested schema](#nestedatt--attestation--azure_firmware_signer_config))
- `bootloader_version` (Number)
- `microcode_version` (Number)
- `snp_version` (Number)
- `tee_version` (Number)
<a id="nestedatt--attestation--azure_firmware_signer_config"></a>
### Nested Schema for `attestation.azure_firmware_signer_config`
Read-Only:
- `accepted_key_digests` (List of String)
- `enforcement_policy` (String)
- `maa_url` (String)
<a id="nestedatt--measurements"></a>
### Nested Schema for `measurements`
Read-Only:
- `expected` (String)
- `warn_only` (Boolean)
