django - How to link from docker-compose to Amazon RDS -


my docker-compose.yml looks this:

django:   build: .   user: django   links:     # link amazon rds?   command: /gunicorn.sh   env_file: config/settings/.env  nginx:   build: ./compose/nginx   links:     - django   ports:     - "0.0.0.0:80:80"

how link django container amazon rds, has url like: example.blahblahblah.eu-west-1.rds.amazonaws.com:5432

in case, don't have define "link"; database service running, need do, configure django app connect host.

i don't have experience django, based on example in docker-compose documentation, like;

databases = {     'default': {         'engine': 'django.db.backends.postgresql_psycopg2',         'name': 'postgres',         'user': 'postgres',         'host': 'example.blahblahblah.eu-west-1.rds.amazonaws.com',         'port': 5432,     } }

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
