docker - gevent fd は非負でなければなりません: -1

Question

django-websocket-redisを使用して websocket をセットアップしています。また、nginx と docker を使用します。使用法に記載されていることに従いましたが、クライアントからサーバーにアクセスしようとするとエラーが発生しました。

ここに私のnginx.confがあります

  location /api {
    include             /etc/nginx/uwsgi_params;
    uwsgi_param         HTTP_HOST {{ 'DOMAIN_NAME' | env }};
    uwsgi_pass          uwsgi://{{ upstream }};
    uwsgi_read_timeout  600;
}

 location /ws/ {
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    include         /etc/nginx/uwsgi_params;
    uwsgi_param     HTTP_HOST {{ 'DOMAIN_NAME' | env }};
    uwsgi_pass      unix:///tmp/app_ws.sock;
}

そしてここに私のuwsgi：

[uwsgi]

# Django-related settings
# the base directory (full path)
chdir               = $(SRC)/
# Django's wsgi file
module              = config.wsgi
# the virtualenv (full path)
# home                = $(DEPLOY_ROOT)/app/
# process-related settings
# master
master              = true

# set up app load optimizations
workers             = 4         # maximum number of workers
cheaper             = 2         # minimum number of workers at all times
cheaper-initial     = 2         # num. of workers spawned at startup
cheaper-step        = 1         # num. of workers spawned when algo decides more are needed
cheaper-algo        = spare     # (spare2) faster spawning, slower disposing
cheaper-busyness-verbose = true

# align header size with ELB
buffer-size         = 16384

# use network socket
socket              = :xxxx

# clear environment on exit
vacuum              = true

# reload django app on file change (debug only)
if-env              = PYTHON_AUTORELOAD
python-autoreload   = %(_)
end-if              =

pythonpath          = $(SRC)/
base                = $(SRC)/

これが私のwebsocket用のuwsgiです：

[uwsgi]

# Django-related settings
# the base directory (full path)
chdir               = $(SRC)/
# Django's wsgi file
module              = config.wsgi_websocket
# the virtualenv (full path)
# home                = $(DEPLOY_ROOT)/app/

http-websockets = true
gevent          = 1000

# process-related settings
# master
master          = true

# set up app load optimizations
workers         = 4         # maximum number of workers
cheap           = 2         # minimum number of workers at all times
cheaper-initial = 2         # num. of workers spawned at startup
cheaper-step    = 1         # num. of workers spawned when algo decides more are needed
cheaper-algo    = spare     # (spare2) faster spawning, slower disposing

# align header size with ELB
buffer-size     = 16384
# the socket (use the full path to be safe
socket          = /tmp/app_ws.sock
# ... with appropriate permissions - may be needed
chmod-socket    = 667
# clear environment on exit
vacuum          = true

# reload django app on file change (debug only)
if-env = PYTHON_AUTORELOAD
python-autoreload = %(_)
end-if =


pythonpath          = $(SRC)/
base                = $(SRC)/

これが私が得たエラーです。

また、websocket がなくても、私のアプリは正常に動作します。つまり、/api の下の URL にアクセスできます。
