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 general guidance for managing cluster peering connections, refer to [Manage L7 traffic with cluster peering](/consul/docs/connect/cluster-peering/usage/peering-traffic-management). ## Reset a peering connection To reset the cluster peering connection, you need to generate a new peering token from the cluster where you created the `PeeringAcceptor` CRD. The only way to create or set a new peering token is to manually adjust the value of the annotation `consul.hashicorp.com/peering-version`. Creating a new token causes the previous token to expire. 1. In the `PeeringAcceptor` CRD, add the annotation `consul.hashicorp.com/peering-version`. If the annotation already exists, update its value to a higher version. ```yaml apiVersion: consul.hashicorp.com/v1alpha1 kind: PeeringAcceptor metadata: name: cluster-02 annotations: consul.hashicorp.com/peering-version: "1" ## The peering version you want to set, must be in quotes spec: peer: secret: name: "peering-token" key: "data" backend: "kubernetes" ``` 1. After updating `PeeringAcceptor`, repeat all of the steps to [establish a new peering connection](/consul/docs/k8s/connect/cluster-peering/usage/establish-peering). ## List all peering connections In Consul on Kubernetes deployments, you can list all active peering connections in a cluster using the Consul CLI. 1. If necessary, [configure your CLI to interact with the Consul cluster](/consul/tutorials/get-started-kubernetes/kubernetes-gs-deploy#configure-your-cli-to-interact-with-consul-cluster). 1. Run the [`consul peering list` CLI command](/consul/commands/peering/list). ```shell-session $ consul peering list Name State Imported Svcs Exported Svcs Meta cluster-02 ACTIVE 0 2 env=production cluster-03 PENDING 0 0 ``` ## Read a peering connection In Consul on Kubernetes deployments, you can get information about individual peering connections between clusters using the Consul CLI. 1. If necessary, [configure your CLI to interact with the Consul cluster](/consul/tutorials/get-started-kubernetes/kubernetes-gs-deploy#configure-your-cli-to-interact-with-consul-cluster). 1. Run the [`consul peering read` CLI command](/consul/commands/peering/read). ```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 ``` ## Delete peering connections To end a peering connection in Kubernetes deployments, delete both the `PeeringAcceptor` and `PeeringDialer` resources. 1. Delete the `PeeringDialer` resource from the second cluster. ```shell-session $ kubectl --context $CLUSTER2_CONTEXT delete --filename dialer.yaml ``` 1. Delete the `PeeringAcceptor` resource from the first cluster. ```shell-session $ kubectl --context $CLUSTER1_CONTEXT delete --filename acceptor.yaml ```` To confirm that you deleted your peering connection in `cluster-01`, query the the `/health` HTTP endpoint: 1. Exec into the server pod for the first cluster. ```shell-session $ kubectl exec -it consul-server-0 --context $CLUSTER1_CONTEXT -- /bin/sh ``` 1. If you've enabled ACLs, export an ACL token to access the `/health` HTP endpoint for services. The bootstrap token may be used if an ACL token is not already provisioned. ```shell-session $ export CONSUL_HTTP_TOKEN= ``` 1. Query the the `/health` HTTP endpoint. Peered services with deleted connections should no longe appear. ```shell-session $ curl "localhost:8500/v1/health/connect/backend?peer=cluster-02" ```
