使用docker启动的etcd为什么无法在本地使用restful api接口？

Question

刚研究docker和etcd，按照github中etcd的release中的示例启动了etcd服务：

docker run \
  --rm \
  -p 2379:2379 \
  -p 2380:2380 \
  --name etcd-v3.2.1 \
  --volume=/tmp/etcd-data:/etcd-data \
  quay.io/coreos/etcd:v3.2.1 \
  /usr/local/bin/etcd \
  --name my-etcd-1 \
  --data-dir /etcd-data \
  --listen-client-urls http://localhost:2379 \
  --advertise-client-urls http://localhost:2379 \
  --listen-peer-urls http://localhost:2380 \
  --initial-advertise-peer-urls http://localhost:2380 \
  --initial-cluster my-etcd-1=http://localhost:2380 \
  --initial-cluster-token my-etcd-token \
  --initial-cluster-state new \
  --auto-compaction-retention 1

使用如下的命令验证没有问题:

docker exec etcd-v3.2.1 /bin/sh -c "export ETCDCTL_API=3 && /usr/local/bin/etcd -version"
docker exec etcd-v3.2.1 /bin/sh -c "export ETCDCTL_API=3 && /usr/local/bin/etcdctl version"
docker exec etcd-v3.2.1 /bin/sh -c "export ETCDCTL_API=3 && /usr/local/bin/etcdctl endpoint health"
 
docker exec etcd-v3.2.1 /bin/sh -c "export ETCDCTL_API=3 && /usr/local/bin/etcdctl put foo bar"
docker exec etcd-v3.2.1 /bin/sh -c "export ETCDCTL_API=3 && /usr/local/bin/etcdctl get --consistency=s foo"

但是我在本地主机使用restful api访问2379端口时，没有响应信息返回:

请问为什么restful接口无法调用成功呢？
