如何构建 Node Server 的镜像？

首先是要将 Node Server 进行Docker 化，直接在项目中加入 Dockerfile。
nginx 的配置文件如下

server {

listen 80;
server_name example.org;
server_tokens off;
location /.well-known/acme-challenge/ {
    root /var/www/certbot;
}
location / {
    return 301 
}

}
server {

listen 443 ssl;
server_name example.org;
server_tokens off;
ssl_certificate /etc/letsencrypt/live/example.org/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.org/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
location / {
    proxy_pass  
    proxy_set_header    Host                $http_host;
    proxy_set_header    X-Real-IP           $remote_addr;
    proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
}

}
拼装 Node Server + Nginx
我们现在已经获得了一个有了合法证书的 Nginx 页游的服务器了，将 node server 接在 Nginx 的后面就大功告成了。 我们直接在前面的boilerplate中提供的 docker-compose.yml 进行一些修改。

version: "3"
services:
nodeapp:

image: nodeserver:1.0.0
container_name: nodeapp
restart: unless-stopped
volumes:
  - /data/usersFolder:/server/config
ports:
  - "3000:3000"
networks:
  - app-network

nginx:

image: nginx:1.15-alpine
container_name: nginx_server
restart: unless-stopped
volumes:
  - ./data/nginx:/etwww.pizei.comc/nginx/conf.d
  - ./data/certbot/conf:/etc/letsencrypt
  - ./data/certbot/www:/var/www/certbot
ports:
  - "80:80"
  - "443:443"
networks:
  - app-network
command: '/bin/sh -c ''while :; do sleep 6h & wait $${!}; nginx -s reload; done & nginx -g "daemon off;"'''

certbot:

image: certbot/certbot
restart: unless-stopped
container_name: certbot_one
volumes:
  - ./data/certbot/conf:/etc/letsencrypt
  - ./data/certbot/www:/var/www/certbot
entrypoint: "/bin/sh -c 'trap exit TERM; while :; do certbot renew; sleep 12h & wait $${!}; done;'"

networks:
app-network:

driver: bridge

通过创建一个 network 来让 nginx 直接和 node server 通信，nginx 的conf 也可以写的比较顺滑。以前我记得可以使用 —link 来进行容器间通信，但官方更推荐的做法还是创建一个 network
