我正在尝试使用配置了gunicorn和nginx的django应用程序进行docker化。我正在这里（http://pawamoy.github.io/2018/02/01/docker-compose-django-postgres-nginx.html）进行学习。
然后，当我尝试做 from boto3.session import Session
s = Session()
regions = s.get_available_regions('rds')
print("regions:", regions)
$ python3 regions.py
regions: ['ap-northeast-1', 'ap-northeast-2', 'ap-south-1', 'ap-southeast-1', 'ap-southeast-2', 'ca-central-1', 'eu-central-1', 'eu-west-1', 'eu-west-2', 'eu-west-3', 'sa-east-1', 'us-east-1', 'us-east-2', 'us-west-1', 'us-west-2']
时，我得到以下信息。
docker-compose up --build在网络上，我会收到502 Bad Gateway。
因此，当我查看错误日志时，这就是我得到的。

docker-compose.yml这是我的nginx的version: '3'

。
local.conf我尝试弄乱# Declare upstream server (Gunicorn application)
upstream iedb_server {
server iedb_tools:8000;
}
# Declare main server
server {
listen 80;
server_name localhost;
location / {
# Everthing is passed to Gunicorn
proxy_read_timeout 300s;
proxy_connect_timeout 120s;
proxy_pass http://iedb_server;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
}
，但是没有用。我尝试从proxy_read/connect_timeout注释掉listen 80 default_server;和listen [::]:80 ipv6only=on default_server;。似乎也不起作用。
非常感谢有人可以帮助我。谢谢！
