ubuntu - Server setup: Subdomain or different port for API and single or multiple ssl certificates for a docker, nginx, web and api setup? -


i using digital ocean ubuntu 15.10 server. have 3 docker containers: nginx, web (for angular 2 app), , rails rails api.

i planning on setting nginx configuration file follows:

port 443 proxy passed nginx web app.

after i'm bit confused on how should allow outside access rails api? should make rails api accessible through subdomain , if how? or should use same domain web app although different port?

next question need 1 ssl certificate outside world connecting nginx layer? or need 1 ssl certificate web application , 1 ssl certificate rails api?

you can use nginx load balancer both endpoints. should fine:

upstream web {     server webcontainer1:8080;     server webcontainer2:8080; }  upstream api {     server apicontainer1:5000;     server apicontainer2:5000; }  server {     <your_server_directives>     ...      location /api {         proxy_pass http://api;     }      location / {         proxy_pass http://web;     } }

you subdomain separate nginx. in case setup server directive , virtual hosting on same port or api specific port like:

upstream api {     server apicontainer1:5000;     server apicontainer2:5000; }  server {     listen 5500;     server_name api.mydomain.com;      location /api {         proxy_pass http://api;     } }

in first scenario, yes, can 1 ssl certificate api , web on 1 port (one domain name). in second scenario, you'd need wildcard certificate or 2 certificates, 1 main web (yourdomain.com) , api (api.yourdomain.com).

it worth noting second scenario can run annoying csrf issues because ssl pages not allow xhr requests outside current domain. can second subdomain api, end needing 3rd proxy in nginx config proxy yourdomain.com/api api.yourdomain.com.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
