我有带有 3 个控制器和 3 个常规节点的 UCP 集群。我第一次能够成功设置集群。但是，我正在尝试在其中一个控制器上进行全新安装，但在运行 join 命令时出现以下错误：

a
INFO[0001] Verifying your system is compatible with UCP
INFO[0001] Checking that required ports are available and accessible
INFO[0117] Starting local swarm containers
INFO[0120] Starting UCP Controller replica containers
ERRO[0120] Server response: {"message":"etcdserver: peerURL exists"}
ERRO[0120] Failed to start KV store.  Run "docker logs ucp-kv" for more details
FATA[0120] Failed to add member to KV store: {"message":"etcdserver: peerURL exists"}

我正在运行以下连接命令：

docker run --rm -it \
  --name ucp \
  -v /var/run/docker.sock:/var/run/docker.sock \
  docker/ucp:1.1.3 \
  join --replica --interactive
