Question

我有一台运行Nginx和Docker的Ubuntu服务器。我的Docker容器正在端口4200上运行。

docker run -d -p4200:4200 my-app:latest

我可以确认它正在运行

CONTAINER ID        IMAGE                             COMMAND                  CREATED             STATUS              PORTS                            NAMES
f5be8856b9e2        my-app:latest   "nginx -g 'daemon of…"   3 minutes ago       Up 3 minutes        80/tcp, 0.0.0.0:4200->4200/tcp   hopeful_diffie

我已经像这样设置了我的Nginx默认配置文件：

server {

    root /var/www/html;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name my-app.com;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        proxy_pass http://localhost:4200/;
    }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/my-app.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/my-app.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

server {

    root /var/www/html;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;
    server_name www.my-app.com; # managed by Certbot


    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        proxy_pass http://localhost:4200/;
    }

    listen [::]:443 ssl ; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/my-app.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/my-app.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = my-app.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80 default_server;
    listen [:

:]:80 default_server;

    server_name my-app.com;
    return 404; # managed by Certbot


}
server {
    if ($host = www.my-app.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80 ;
    listen [::]:80 ;
    server_name www.my-app.com;
    return 404; # managed by Certbot
}

在尝试添加proxy_pass之前（将proxy_pass行切换到try_files $ uri $ uri / = 404;），我正在获取默认的nginx页面。我希望添加proxy_pass行将请求转发到运行Docker容器的服务器端口4200。相反，我得到了502 Bad Gateway。我以为问题出在我的Ngnix配置中，但我不确定自己做错了什么？任何帮助都会很棒。

这对我来说是一个愚蠢的错误，但这也许会在将来对某人有所帮助。它在我的docker run命令中。

docker run -d -p 4200:80 my-app:latest

我的Docker容器内部正在监听80，但我将其发送到4200。

如何为我的Docker容器的代理设置Nginx Config File并letencrypt？
