Question

我正在尝试将运行Next.js和NGINX的Docker容器部署到Google Compute Engine。当使用docker-compose up部署在本地时，它可以完美工作，但是部署到CE时，我会收到错误

[emerg] 1#1: host not found in upstream "nextjs:3000" in /etc/nginx/conf.d/default.conf:4

本地日志是

Attaching to nextjs, profiles-fe_nginx_1
nextjs    | 2019-05-02T03:51:26: PM2 log: Launching in no daemon mode
nextjs    | 2019-05-02T03:51:26: PM2 log: App [npm:0] starting in -fork mode-
nextjs    | 2019-05-02T03:51:26: PM2 log: App [npm:0] online
nextjs    | > create-next-example-app@ start /usr/app
nextjs    | > NODE_ENV=production node server.js
nextjs    | > Ready on http://localhost:3000

部署到CE命令

docker-compose build

docker tag <local_container> <remote_container>

docker push <remove_container

gcloud beta compute --project=<project_name> instances create-with-container <instance_name> --zone=europe-west2-c --machine-type=g1-small --container-image=<remove_container> --tags http-server,https-server

default.conf

  server nextjs:3000;
}

  location /_next/static {

    proxy_pass http://app;
  }

  # 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://app;
  }

  # DYNAMIC ASSETS - NO CACHE
  location / {

}
