我有一个nextjs项目，希望使用Docker和nginx运行。
我希望在后台使用连接到nextjs的nginx(只有nginx可以与nextjs对话，用户需要与nginx对话才能与nextjs对话(。
假设它是标准的nextjs项目结构和dockerfile内容(下面提供(，有没有办法在docker中使用nginx和nextjs？
我知道我可以使用Docker compose。但我想把它放在一个码头工人的形象下。由于我计划将图片推送到heroku网站托管。
注意：我使用的是服务器端渲染

为了能够在一个Docker容器中同时使用Nginx和NextJS而无需使用Docker Compose，您需要使用Supervisord
Supervisor是一个客户端/服务器系统，允许其用户控制类UNIX操作系统上的许多进程。
问题不是nginx配置或dockerfile。启动容器时，它同时运行nginx和nextjs。由于我找不到同时运行这两者的方法，所以使用supervisord是我需要的工具。
工作需要以下内容
Dockerfile
# Base on offical Node.js Alpine image
FROM node:latest as builder
# Set working directory
WORKDIR /usr/app
# Copy package.json and package-lock.json before other files
# Utilise Docker cache to save re-installing dependencies if unchanged
COPY package.json ./
COPY yarn.lock ./
# Install dependencies
RUN yarn install --frozen-lockfile
# Copy all files
COPY ./ ./
# Build app
RUN yarn build
# remove development dependencies
RUN yarn install --production

注意：使用nginx作为反向代理。NextJS将在端口3000上运行。用户将无法直接访问它。它必须通过nginx。
建筑码头图像
docker build -t nextjs-img -f ./dockerfile .
正在运行码头集装箱
docker run --rm -e 'PORT=80' -p 8080:80 -d --name nextjs-img nextjs-img:latest
转到localhost:8080
您可以使用docker-compose在Docker容器中运行Nginx和您的NextJS应用程序，然后在这些容器之间建立一个桥接网络。
然后在nginx-conf:中
server {
listen 80;
listen 443 ssl;
server_name localhost [dns].com;
ssl_certificate certs/cert.pem;
ssl_certificate_key certs/cert.key;
location / {
proxy_pass http://nextApplication; // name based on your docker-compose file
proxy_http_version 1.1;
proxy_read_timeout 90;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host [dns].com;
proxy_cache_bypass $http_upgrade;
}
}
