我正在尝试从快照中恢复 Amazon ECS 上的 5 节点 ETCD 集群（使用 DNS 发现），但发生的情况是每个节点都作为单节点集群启动，并且节点没有相互添加成员。
etcd 的 docker 容器内的启动脚本如下
THIS_IP=$(curl http://169.254.169.254/latest/meta-data/local-ipv4)
THIS_NAME=$(curl http://169.254.169.254/latest/meta-data/hostname | cut -d . -f 1)
aws s3 cp s3://test_bucket/snapshot.db .
if [ -f "./snapshot.db" ]; then
echo "restoring from db...."
ETCDCTL_API=3 etcdctl --data-dir ${THIS_NAME}.etcd snapshot restore snapshot.db
fi
etcd --data-dir=${THIS_NAME}.etcd --name ${THIS_NAME} --discovery-srv ${DISCOVERY_SRV} --initial-advertise-peer-urls http://${THIS_IP}:2380 --listen-peer-urls http://0.0.0.0:2380 --advertise-client-urls http://${THIS_IP}:2380 --listen-client-urls http://0.0.0.0:2379 --initial-cluster-state ${CLUSTER_STATE} --initial-cluster-token ${TOKEN}
它的工作方式是节点名称（THIS_NAME）成为与容器的 ip 地址相关的东西，例如ip-10-0-6-22，并且私有 ip 地址（THIS_IP）是通过亚马逊 ip 元数据检索的。
日志看起来像这样
