# Partition Exports

This topic describes the `partition-exports` configuration entry type. The `partition-exports` configuration entry enables Consul to export service instances to other admin partitions from a single file. This enables your services to be networked across admin partitions.    

-> **v1.11.0+:** This config entry is supported in Consul versions 1.11.0+.

## Introduction

You can configure Consul to export services contained in an admin partition to one or more additional partitions by declaring the `partition-exports` configuration entry in the `kind` field. This enables you to route traffic between services in different clusters when a single set of Consul servers running on each cluster are jonied using WAN federation. 

The settings defined in the `partition-exports` configuration entry apply to all namespaces and federated datacenters.

TO DO: More background info and info about the use case(s).

## Requirements

The consumer partition must have an `upstream` configuration that specifies the destination for the services. Refer to the [Upstream Configuration Reference](/docs/connect/registration/service-registration#upstream-configuration-reference) for information on how to configure the upstream.

## Usage

1. Verify that your datacenter meets the conditions specified in the [Requirements](#requirements).
1. Specify the `partition-exports` configuration in the agent configuration file as described in [Configuration](#configuration).
1. Deploy the configuration per your runtime:
    * [VM](/docs/install) 
    * [Kubernetes](/docs/k8s/installation/install) 

## Configuration

Configure the following parameters to define a `partition-exports` configuration entry:

<CodeTabs heading="Partition exports configuration syntax" tabs={[ "HCL", "Kubernetes YAML", "JSON" ]}>
<CodeBlockConfig>

```hcl
Kind = "partition-exports"
Partition = "<partition containing services to export>"
Services = [
  {
    Name = "<name of service to export>"
    Namespace = "<namespace of namespace in the partition>"  
    Consumers = [
      {
        Partition = "<name of destination partition>"
      },      
    ]
  }
]
```
</CodeBlockConfig>
<CodeBlockConfig>

```yaml
apiVersion: consul.hashicorp.com/v1alpha1
Kind: PartitionExports
Partition: <partition containing services to export>
Services:
- Consumers:
  - Partition: <name of destination partition>
  Name: <name of service to export>
  Namespace: <namespace of namespace in the partition>
```
</CodeBlockConfig>
<CodeBlockConfig>

```json
"Kind": "partition-exports",
"Partition": "<partition containing services to export>",
"Services": [
  {
    "Consumers": [
      {
        "Partition": "<name of destination partition>"
      }
    ],
    "Name": "<name of service to export>",
    "Namespace": "<namespace of namespace in the partition>"
  }
]
```
</CodeBlockConfig>
</CodeTabs>

### Configuration Parameters

The following table describes the parameters associated with the `partition-exports` configuration entry.

| Parameter | Description | Required | Default |
| ---       | ---         | ---      | ---     |
| `Kind`    | String value that enables the configuration entry. The value should always be `partition-exports` (HCL and JSON) or `PartitionExports` (YAML) | Required | None |
| `Partition` | String value that specifies the name of the partition that contains the services you want to export. | Required | None |
| `Services` | List of objects that specify which services to export. See [`Services`](#services) for details. | Required | None| 
| `Meta` | Object that defines a map of the max 64 key/value pairs. | Optional | None |

#### `Services`

The `Services` parameter contains one or more lists of parameters that specify which services to export, which namespaces the services reside, and the destination partition for the exported services. Each list in the `Services` block must contain the following parameters:

* `Name`: Specifies the name of the service to export. You can use a asterisk wildcard (`*`) to include all services in the namespace. 
* `Namespace`: Specifies the name space containing the services to export. You can use a asterisk wildcard (`*`) to include all namespaces in the partition.
* `Consumers`: Specifies one ore more objects that identify a destination partition for the exported services. 

## Example

The following example configures the agent to export the `billing` service from the `default` namespace of the `finance` admin partition to the `frontend` and `backend` partitions. Additionally, all services in all namespaces within the `finance` partition will be exported to the `monitoring` partition. 

<CodeTabs heading="" tabs={[ "HCL", "Kubernetes YAML", "JSON" ]}>
<CodeBlockConfig>

```hcl
Kind = "partition-exports" 
Partition = "finance"

Services = [
  {
    Name = "billing"
    Namespace = "default"
    Consumers = [
        {
            Partition  = "frontend"
        },
        {
            Partition  = "backend"
        }
    ]
  },
  {
    Name      = "*"
    Namespace = "*"
    Consumers = [
        {
            Partition  = "monitoring"
        }
    ]
  }
]
```

</CodeBlockConfig>
<CodeBlockConfig>

```yaml
Kind: partition-exports
Partition: finance
Services:
- Consumers:
  - Partition: frontend
  - Partition: backend
  Name: billing
  Namespace: default
- Consumers:
  - Partition: monitoring
  Name: '*'
  Namespace: '*'
```

</CodeBlockConfig>
<CodeBlockConfig>

```json
"Kind": "partition-exports",
  "Partition": "finance",
  "Services": [
    {
      "Consumers": [
        {
          "Partition": "frontend"
        },
        {
          "Partition": "backend"
        }
      ],
      "Name": "billing",
      "Namespace": "default"
    },
    {
      "Consumers": [
        {
          "Partition": "monitoring"
        }
      ],
      "Name": "*",
      "Namespace": "*"
    }
  ]
```

</CodeBlockConfig>
</CodeTabs>

## Reading Services

When an exported service has been imported to another partition, you can use the `health` REST API endpoint to query the service on the consumer partition. The following example queries the `finance` partition for the imported `billing` service:

```shell-session
$ curl 'localhost:8500/v1/health/connect/billing?partition=finance'
```

See [Health HTTP Endpoing](/api-docs/health) for additional information.
