multi docker nginx + nodejs 心得


  1. 用nginx prxoy 可以mapping到不同的image,但外部可以持續用相同的cookie . 
  2. 多專案debug時,直接用內網ip做 proxy_pass就可以了
  3. 用docker-compose做 multi docker,做link後,所有的port都不需要開到外部去,增加安全性.



server {
listen 80;
server_name localhost;
location /test {
proxy_pass http://app:3000/test; # proxy_pass http://192.168.1.100:3000/test;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
location / {
proxy_pass http://app2:3001; # proxy_pass http://192.168.1.100:3001;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
location /parse {
proxy_pass http://parse-server:1337/parse; # proxy_pass http://192.168.1.100:1337/parse;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
