Answer 1

If you follow the etcd guide, check if this point to the machine you are running the command on:

THIS_NAME=${NAME_4}
THIS_IP=${HOST_4}

Replace 4 with the correct number.

Answer 2

I got the same error when trying to bind to the server's IP. I fixed this (though, not sure what the consequence will be) by adding 0.0.0.0 in both --listen-peer-urls and --listen-client-urls:

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}

Used curl to verify working cluster:

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"]}]}

Docker command comes directly from coreos etcd website: https://coreos.com/etcd/docs/3.2.9/op-guide/container.html#docker
