How to build a node server image?

First, docker the node server and directly add dockerfile to the project.
The configuration file of nginx is as follows

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;
}

}
Assembling node server + nginx
We have now obtained an nginx with a legal certificateWebpage GameConnect the node server to the back of nginx. We directly provided docker – compose. In the previous boilerplate YML makes some changes.

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

By creating a network to let nginx communicate directly with the node server, the conf of nginx can also be written smoothly. In the past, I remember that – link can be used for inter container communication, but the official recommended practice is to create a network
