# Cluster Peering - HTTP API
|
|
|
|
~> **Cluster peering is currently in technical preview:** Functionality associated
|
|
with cluster peering is subject to change. You should never use the technical
|
|
preview release in secure environments or production scenarios. Features in
|
|
technical preview may have performance issues, scaling issues, and limited support.
|
|
|
|
The functionality described here is available only in
|
|
[Consul](https://www.hashicorp.com/products/consul/) version 1.13.0 and later.
|
|
|
|
## Generate a Peering Token

|
| ------- | -------------------- | ------------------ |
|
|
| `POST` | `/peering/token` | `application/json` |
|
|

|
The table below shows this endpoint's support for
|
|
[blocking queries](/api-docs/features/blocking),
|
|
[consistency modes](/api-docs/features/consistency),
|
|
[agent caching](/api-docs/features/caching), and
|
|
[required ACLs](/api#authentication).

### JSON Request Body Schema
|
|
|
|
- `PeerName` `(string: <required>)` - The name assigned to the peer cluster.
|
|
The `PeerName` is used to reference the peer cluster in service discovery queries
|
|
and configuration entries such as `service-intentions`. This field must be a
|
|
valid DNS hostname label.
|
|
|
|
- `Partition` `(string: "")` - <EnterpriseAlert inline /> The admin partition that the
|
|
peering token is generated from. Uses `default` when not specified.
|
|
|
|
- `ServerExternalAddresses` `([]string: <optional>)` - A list of addresses to put
|
|
into the generated token. Addresses are the form of `{host or IP}:port`.
|
|
You can specify one or more load balancers or external IPs that route external traffic to this cluster's Consul servers.
|
|
|
|
- `Meta` `(map<string|string>: <optional>)` - Specifies KV metadata to associate with
|
|
the peering. This parameter is not required and does not directly impact the cluster
|
|
peering process.
|
|
|
|

|
field will be populated with the timestamp of when the peering was marked for deletion.
