Question

我正在将Next.js / Nginx Docker映像从Container Registry部署到Compute Engine

部署后，该应用程序将按预期运行，但它将在端口3000而不是80上运行-即我想在<ip_address>上访问它，但我只能在<ip_address>:3000上访问它。我已经在Nginx中设置了反向代理，以将端口3000转发到80，但是它似乎不起作用。

当我运行docker-compose up时，可以在localhost上访问该应用程序（而不是localhost:3000）

Dockerfile

FROM node:alpine as react-build

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY package.json /usr/src/app
RUN npm install
RUN npm install --global pm2

COPY . /usr/src/app
RUN npm run build
# EXPOSE 3000
EXPOSE 80

CMD [ "pm2-runtime", "start", "npm", "--", "start" ]

docker-compose.yml

version: '3'
services:
  nextjs: 
    build: ./
  nginx: 
    build: ./nginx
    ports:
      - 80:80

./ nginx / Dockerfile

FROM nginx:alpine

# Remove any existing config files
RUN rm /etc/nginx/conf.d/*

# Copy config files
# *.conf files in "conf.d/" dir get included in main config
COPY ./default.conf /etc/nginx/conf.d/

./ nginx / default.conf

  # BUILT ASSETS (E.G. JS BUNDLES)

  # Server cache - valid forever (cleared after cache "inactive" period)
  location /_next/static {
    #proxy_cache STATIC;
    proxy_pass http://localhost:3000;
  }

  # STATIC ASSETS (E.G. IMAGES)
  # Browser cache - "no-cache" headers from Next.js as no build id in url
  # Server cache - refresh regularly in case of changes
  location /static {
    #proxy_cache STATIC;
    proxy_ignore_headers Cache-Control;
    proxy_cache_valid 60m;
    proxy_pass http://locahost:3000;
  }

  # DYNAMIC ASSETS - NO CACHE
  location / {
    proxy_pass http://locahost:3000;
  }
}

Google Compute Engine上的Docker映像无法在端口80上运行
