DH Conferences CRUD App

Application for editing, searching, and browsing historical DH conference abstracts.

Development lead: Matthew Lincoln

Overview

This is a Django application orchestrated with Docker Compose, comprising 4 key services:

nginx

The application is served behind nginx. /nginx/nginx.template shows the suggested formation of your default.conf file, setting up the reverse proxy to the Django service and serving the static files. the /nginx folder is passed as a volume to /etc/nginx/conf.d in the nginx docker container.

memcached

Cache set up for Django

postgres

The Django app relies on several PostgreSQL-only functions and fields, including its serviceable full-text search. Data is stored in a named db docker volume.

make backup will dump the database to the /data folder

django

This is the core Django service, which builds from /dh_abstracts/Dockerfile. The python libraries are specified in /dh_abstracts/requirements.txt, installed when the Dockerfile is built.

Deployment

Running this stack locally or in production requires an .env file based on .env.template, with selected db password and secret, and the proper hostname, email server etc.

In production we currently use gunicorn to serve, so the SERVE_COMMAND is set to 'gunicorn dhweb.wsgi -b 0.0.0.0:8000 -w $SOME_INT' where the number of workers $SOME_INT is appropriate to the number of cores on the deployent machine.

Updates

Update nginx, memcached, and postgres versions by incrementing their version tags in docker-compose.yml

Update underlying Python version in dh_abstracts/Dockerfile

Update python packages in requirements.txt.
