## Deployment Attributes
This document defines attributes for software deployments.
| Attribute | Type | Description | Examples | Stability |
|---|---|---|---|---|
| `deployment.environment.name` | string | Name of the [deployment environment](https://wikipedia.org/wiki/Deployment_environment) (aka deployment tier). [1] | `staging`; `production` |  |
| `deployment.id` | string | The id of the deployment. | `1208` |  |
| `deployment.name` | string | The name of the deployment. | `deploy my app`; `deploy-frontend` |  |
| `deployment.status` | string | The status of the deployment. | `failed`; `succeeded` |  |
**[1] `deployment.environment.name`:** `deployment.environment.name` does not affect the uniqueness constraints defined through
the `service.namespace`, `service.name` and `service.instance.id` resource attributes.
This implies that resources carrying the following attribute combinations MUST be
considered to be identifying the same service:
- `service.name=frontend`, `deployment.environment.name=production`
- `service.name=frontend`, `deployment.environment.name=staging`.
---
`deployment.status` has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.
| Value | Description | Stability |
|---|---|---|
| `failed` | failed |  |
| `succeeded` | succeeded |  |
## Deployment Deprecated Attributes
"Describes deprecated deployment attributes."
| Attribute | Type | Description | Examples | Stability |
|---|---|---|---|---|
| `deployment.environment` | string | 'Deprecated, use `deployment.environment.name` instead.' | `staging`; `production` | 
Deprecated, use `deployment.environment.name` instead. |
