启动 etcd 因“bind:无法分配请求的地址”而失败

Question

我将 etcd 作为 docker 容器运行，10.132.41.234 是我运行 docker 容器的主机 IP，我收到这样的错误信息，我不知道它是否正确，我现在熟悉 etcd，有人可以提供帮助？谢谢！

当尝试绑定到服务器的 IP 时，我遇到了同样的错误。我通过在 --listen-peer-urls 和 --listen-client-urls 中添加 0.0.0.0 修复了这个问题（不过，不确定结果是什么）：

docker run --net=host -d -p 2379:2379 \
  -p 2380:2380 \
  --restart=always \
  --volume=${DATA_DIR}:/etcd-data \
  --name etcd0 quay.io/coreos/etcd:${ETCD_VERSION} \
  /usr/local/bin/etcd \
  --data-dir=/etcd-data --name ${THIS_NAME} \
  --initial-advertise-peer-urls http://${THIS_IP}:2380 --listen-peer-urls http://0.0.0.0:2380 \
  --advertise-client-urls http://${THIS_IP}:2379 --listen-client-urls http://0.0.0.0:2379** \
  --initial-cluster ${CLUSTER} \
  --initial-cluster-state ${CLUSTER_STATE} --initial-cluster-token ${TOKEN}

使用curl验证工作集群：

curl http://IP:2379/v2/members
{"members":[{"id":"d587abebd4bc78d","name":"etcd1","peerURLs":["http://IP:2380"],"clientURLs":["http://IP:2379"]},{"id":"17efb04cb71d981c","name":"etcd0","peerURLs":["http://IP:2380"],"clientURLs":["http://IP:2379"]},{"id":"3d50a0b6f7f6bda6","name":"etcd3","peerURLs":["http://IP:2380"],"clientURLs":["http://IP:2379"]}]}
