docker uwsgi container 和本地 nginx 无法连通，返回 502

本来是想 nginx 和 uwsgi 各自放一个 container. 通过 volume 映射 unix socket.但目前 uwsgi container 和本地的 nginx 都跑不通。。。同样的 uwsgi.ini 如果在本地直接运行则没有任何问题。

nginx 一直是 61 connection refused

[error] 12033#0: *1 connect() to unix:/tmp/uwsgi.sock failed (61: Connection refused) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/tmp/uwsgi.sock:", host: "localhost"

socket 在本地的映射(container volume 映射和本地直接运行 uwsgi 完全一样)
