# Manage cluster peering connections
|
|
|
|
This usage topic describes how to manage cluster peering connections using the CLI, the HTTP API, and the UI.
|
|
|
|
After you establish a cluster peering connection, you can get a list of all active peering connections, read a specific peering connection's information, and delete peering connections.
|
|
|
|
For Kubernetes-specific guidance for managing cluster peering connections, refer to [Manage cluster peering connections on Kubernetes](/consul/docs/k8s/connect/cluster-peering/usage/manage-peering).
|
|
|
|
## List all peering connections
|
|
|
|
You can list all active peering connections in a cluster.
|
|
|
|
<Tabs>
|
|
<Tab heading="Consul CLI" group="cli">
|
|
|
|
```shell-session
|
|
$ consul peering list
|
|
Name State Imported Svcs Exported Svcs Meta
|
|
cluster-02 ACTIVE 0 2 env=production
|
|
cluster-03 PENDING 0 0
|
|
```
|
|
|
|
For more information, including optional flags and parameters, refer to the [`consul peering list` CLI command reference](/consul/commands/peering/list).
|
|
|
|
</Tab>
|
|
<Tab heading="HTTP API" group="api">
|
|
|
|
The following example shows how to format an API request to list peering connections:
|
|
|
|
```shell-session
|
|
$ curl --header "X-Consul-Token: 0137db51-5895-4c25-b6cd-d9ed992f4a52" http://127.0.0.1:8500/v1/peerings
|
|
```
|
|
|
|
For more information, including optional parameters and sample responses, refer to the [`/peering` endpoint reference](/consul/api-docs/peering#list-all-peerings).
|
|
|
|
</Tab>
|
|
<Tab heading="Consul UI" group="ui">
|
|
|
|
In the Consul UI, click **Peers**.
|
|
|
|
The UI lists peering connections you created for clusters in a datacenter. The name that appears in the list is the name of the cluster in a different datacenter with an established peering connection.
|
|
|
|
</Tab>
|
|
</Tabs>
|
|
|
|
## Read a peering connection
|
|
|
|
You can get information about individual peering connections between clusters.
|
|
|
|
<Tabs>
|
|
|
|
<Tab heading="Consul CLI" group="cli">
|
|
|
|
The following example outputs information about a peering connection locally referred to as "cluster-02":
|
|
|
|
```shell-session
|
|
$ consul peering read -name cluster-02
|
|
Name: cluster-02
|
|
ID: 3b001063-8079-b1a6-764c-738af5a39a97
|
|
State: ACTIVE
|
|
Meta:
|
|
env=production
|
|
|
|
Peer ID: e83a315c-027e-bcb1-7c0c-a46650904a05
|
|
Peer Server Name: server.dc1.consul
|
|
Peer CA Pems: 0
|
|
Peer Server Addresses:
|
|
10.0.0.1:8300
|
|
|
|
Imported Services: 0
|
|
Exported Services: 2
|
|
|
|
Create Index: 89
|
|
Modify Index: 89
|
|
```
|
|
|
|

<Tab heading="HTTP API" group="api">
|
|
|
|
```shell-session
|
|
$ curl --header "X-Consul-Token: b23b3cad-5ea1-4413-919e-c76884b9ad60" http://127.0.0.1:8500/v1/peering/cluster-02

1. In the Consul UI, click **Peers**.
|
|
|
|
1. Click the name of a peered cluster to view additional details about the peering connection.
|

|

</Tab>
|
|
</Tabs>
|
|
|
|
## Delete peering connections
|
|
|
|
You can disconnect the peered clusters by deleting their connection. Deleting a peering connection stops data replication to the peer and deletes imported data, including services and CA certificates.

|
The following examples deletes a peering connection to a cluster locally referred to as "cluster-02":
|
|
|
|
```shell-session
|
|
$ consul peering delete -name cluster-02
|
|
Successfully submitted peering connection, cluster-02, for deletion

|
|
|
|
```shell-session
|

|
|
|
1. In the Consul UI, click **Peers**. The UI lists peering connections you created for clusters in that datacenter.
|
|
1. Next to the name of the peer, click **More** (three horizontal dots) and then **Delete**.
|
|
1. Click **Delete** to confirm and remove the peering connection.
