* provide default for dj_database_url.config() sqlite://<PROJECT_ROOT>/askbot.sqlite * enforce TIMEOUT: 6000 * remove /askbot/ segment from MEDIA_ROOT
* should be deployed into the same dir as settings.py * current settings.py does reference it.
* .dockerignore improves the build process * augment_settings.py will be appended to settings.py and is meant to provide some degrees of freedom for container creators * uwsgi.txt is a config snipped we want to use with the (current) base image tiangolo/uwsgi-nginx
* build container with docker build -t TAG_YOUR_STUFF . * docker run TAG_YOUR_STUFF will start an Askbot container using locmem and SQLite * exposes port 8000 by default, change with env var LISTEN_PORT * use existing database by providing the env var DATABASE_URL, e.g. docker run \ -e DATABASE_URL="postgres://askbot:askB0T@1.2.3.4:5432/my_askbot"\ TAG_YOUR_STUFF -d * use existing Redis cluster by providing the env vars ASKBOT_CACHE and CACHE_NODES, e.g. docker run \ -e ASKBOT_CACHE="redis" -e CACHE_NODES="1.2.3.4:6379,2.3.4.5:6379" \ TAG_YOUR_STUFF -d * overwrite admin by providing the env var ADMIN_PASSWORD, e.g. docker run \ -e ADMIN_PASSWORD="supersecret" \ TAG_YOUR_STUFF -d * Don't forget to provide your own SECRET_KEY, e.g. docker run \ -e SECRET_KEY="$(openssl rand 14 | base64)" \ TAG_YOUR_STUFF -d * To persist staticfiles and upfiles use mounts, e.g. docker run \ --mount type=bind,source=/p/a/th,destination=/askbot-site/static \ --mount type=bind,source=/p/a/th,destination=/askbot-site/upfiles \ TAG_YOUR_STUFF -d

This is essentially how I have been building and running dockerized Askbot for the past year.
Askbot has a few dependencies which require a compiler, so I moved to a two-staged build, where the first stage builds all required packages, so that the second stage merely installs whl-files and does not need a build environment.
The main image is built in three steps:
askbot/deployment.For a first glimpse, one should be able to simply
For best results, #864 is applied first. I moved to Python 3.8 a few months ago, but I know 3.7 works just as well. For options see commit message of 8a3f5f3
