我一直在尝试在 docker-compose 中设置一个环境,其中有几个容器:
- 姜戈
- Nginx
- Postgres
- 数据库数据
- 贮存
我使用了以下配置:
app:
restart: always
build: src
expose:
- "8000"
links:
- postgres:postgres
volumes_from:
- storage_files_1
env_file: .env
command: gunicorn barbell.wsgi:application \
-b 0.0.0.0:8000 -w 4
nginx:
restart: always
build: nginx
ports:
- "80:80"
- "443:443"
volumes_from:
- storage_files_1
links:
- app:app
postgres:
restart: always
image: postgres:latest
volumes_from:
- storage_data_1
ports:
- "5432:5432"
我的支持 nginx 站点的配置文件如下所示:
server {
listen 80;
server_name localhost;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
location /static {
alias /static/;
autoindex on;
}
location / {
proxy_pass http://app:8000;
proxy_set_header X-Forwarded-Host $server_name;
proxy_set_header X-Real-IP $remote_addr;
add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
}
}
而且它不起作用 - nginx 总是返回 502,但完美地提供静态文件。我也尝试了与 uwsgi 相同的设置,但没有运气。但是,当我将 Django 与 nginx 结合使用并从同一个容器中提供所有内容时,一切正常(同样,在 uwsgi 和 gunicorn 上)。
知道我错过了什么吗?
更新
以下是 nginx 日志:
*1 connect() failed (111: Connection refused) while connecting to upstream,
