# Create Policy

Learn to create a policy and register the policy

{% hint style="info" %}
**Note**:

If you started Nitride by using the `vhsm nitride init` command then, it performs a series of operations to configure and secure your environment:

1. Creates essential Nitride identities, including: platform, firmware, and workload
2. Creates and attaches a Nitride policy from an embedded policy configuration.
3. Generates attestation objects based on your setup.
4. Bootstraps the environment to allow secure workload attestation and the issuance of access tokens with the appropriate permissions.
5. Ensure that you have set the environment variable: `export VAULT_NAMESPACE=test`  to create a policy in the namespace `test`.
   {% endhint %}

## Create a policy

Create a `policy.json` file that outlines the actions or capabilities and the resources or paths the identity is allowed to access after successful attestation. To create a policy that is attached to a provider see `vhsm nitride policy -help`  command. 

**Example**: Create a `policy.json` file using an editor of your choice. 

```json
{
    "name": "nitride-policy",
    "identities": {
        "provider": "azure-sev-snp-vtpm",
        "platform": [
            {
                "name": "amd-sev-snp-milan-vcek"
            }
        ],
        "firmware": [
            {
                "name": "azure-dc2as-v5"
            }
        ],
        "workload": {
            "name": "azure-sev-snp-vtpm-ubuntu-jammy",
            "policy": {
                "hash": false,
                "pcrs.0": false
            }
        },
        "metadata": null
    }
}
```

Where:

* "name": A string uniquely identifying the policy.
* "identities": An object specifying the required identities for this policy.
* "provider": The provider identity. For example,  azure-sev-snp-vtpm.
* "platform": An array of platform identity objects, see [platform](/nitride/cli/identity/create.md#type-platform) identity structure.
* "firmware": An array of firmware identity objects, see [firmware](/nitride/cli/identity/create.md#type-firmware) identity structure.
* "workload": A workload identity object, see [workload](/nitride/cli/identity/create.md#type-workload) identity structure.
* "metadata": (Optional) Additional metadata for the policy.

### Register the policy

**Example:**

```bash
vhsm nitride policy create @policy.json
```

The `@policy.json` syntax ensures that the CLI can read and embed the file contents directly into the request.

**Output**

```
Key           Value
---           -----
created       1742820324
identities    map[firmware:[map[name:azure-dc2asv5 policy:<nil>]] metadata:<nil> platform:[map[name:amd-sev-snp-milan-vcek policy:<nil>]] provider:azure-sev-snp-vtpm workload:<nil>]
name          nitride-policy
```

### Verify that the policy was created

**Example**:

```
vhsm nitride policy list -namespace=test
```

**Output**

```
Keys
----
aws-c6a.large
azure-dc2asv5-raw
gcp-small
nitride-policy
```

You can also reference this policy in your `attestation.json` to bind it to specific identities. For more information, about updating, reading, or deleting policies, see[ vHSM Nitride CLI.](/nitride/cli/policy.md)
