无法运行 Docker 上的 Nginx HTTPS 网络服务器

Question

我一直在尝试构建一个 Docker 容器来在我的自定义域上设置 Nginx 网络服务器，例如example.com，使用 SSL。这是我的 Dockerfile:

FROM node:latest as build-stage
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY ./ .
RUN npm run build

FROM nginx as production-stage
RUN mkdir /app
COPY --from=build-stage /app/dist /app
COPY nginx.conf /etc/nginx/nginx.conf

nginx.conf:

user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
  worker_connections  1024;
}
http {
  include       /etc/nginx/mime.types;
  default_type  application/octet-stream;
  log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for"';
  access_log  /var/log/nginx/access.log  main;
  sendfile        on;
  keepalive_timeout  65;
  server {
    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.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_name example.com; # managed by Certbot

    location / {
      root   /app;
      index  index.html;
      try_files $uri $uri/ /index.html;
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
      root   /usr/share/nginx/html;
    }
  }
  server {
    if ($host = example.com) {
      return 301 https://$host$request_uri;
    } # managed by Certbot

    listen 80 ;
    listen [::]:80 ;
    server_name example.com;
    return 404; # managed by Certbot
  }
}

然后：

sudo docker build . -t app
sudo docker run -v /etc/letsencrypt/:/etc/letsencrypt/:ro -d -p 443 app

但是，当我访问http://example.com或https://example.com时，网站什么也没有显示，然后连接超时。但是当我访问外部 IP 地址 xx.xxx.xx.xxx/ 时，会显示 Nginx 默认页面。我做错了什么？

Answer 1

主机上安装了nginx，监听80端口，所以用了另一个端口

docker run -d -p 8080:80 my-app

然后尝试再次访问 http://example.com:8080。

或者关闭主机上的 nginx 并使用端口 80。

Answer 2

解决方案比我想象的要容易。

首先，我卸载了宿主机上的nginx，让容器可以连接80端口（其实不需要卸载，用sudo service nginx stop停止nginx服务即可） .

然后，问题出在以下行，端口参数上：

sudo docker run -v /etc/letsencrypt/:/etc/letsencrypt/:ro -d -p 443 app

将其从 -p 443 更改为 -p 80:80 -p 443:443 以启用 HTTP 和 HTTPS 连接，现在它可以正常工作。
