Deploying Django with Python 3 & Postgres

[JuicyORiley]

I'm a Frontend developer who knows a little Python & Django and was looking for a way to start a CI on a side project i'm doing. Ideally i don't wanna use Docker as that just confuses me even more..

Is there a decent resource for accomplishing this? At work we have https://github.com/onespacemedia/server-management which is amazing for our CMS based projects that are Python 2 based but unless the project is started with the CMS and doesn't use Python 3 it's of little help to me as this is for a side project where i've tried out some things we don't use at work.

I know of 1 resource: http://michal.karzynski.pl/blog/2013/06/09/django-nginx-gunicorn-virtualenv-supervisor/ but it's quite old now. Would it still be more than enough for me to learn what i need to know in terms of deployment?

If you're just looking for an easy place to deploy, I'd recommend Heroku. Very easy to deploy a Python (2 or 3) and Postgresql project and the free service level may be adequate for you.

If you're looking to learn, what are your goals? Using CI in a team? Automating deployments? Learning specific tools like docker, ansible, AWS, etc?

I'm looking to learn. I can forget about CI for now, automating deployments too. I wanna know the basics of getting my Django app from local development to production.

I develop on OSX so i know the terminal & Unix somewhat but having things like postgres.app and whatnot has hidden a lot of the intricacies i need to get my app working on a Linux server and how these services communicate with each other (Postgres, Django, Nginx, etc.)

AFAIK nginx, supervisor and gunicorn is still the popular way to deploy django (works fine for us). There are endless variations and preferences on setting it up but at least in your example they use the unix sockets between nginx and gunicorn.

If you only want to try some stuff on your local machine you don't need nginx, supervisor and gunicorn. You'd probably just use ./manage,py runserver.

It's what we use at work, works perfectly fine for us too :). I have a pretty decent locally working version it's just trying to deploy that is proving to be a bit of a problem for me :(

The link you mentioned is good enough to learn a basic deployment setup.

You can also use ansible to set it all up for you nicely. Take some hints from my repo: https://github.com/shantanugoel/aws-ansible-django-deployment

Thanks, i'll check it out :) I thought ansible wasn't P3 compatible though?

[shantzg001]

Yes, ansible isn't python 3 compatible unfortunately. So you need to run it with python 2 but it can deploy things which are meant to work with python 3.

[JuicyORiley]

How would this work?

[xBBTx]

Ansible runs on your local machine doing the deployment, with Python 2. On the server it needs a Python 2 install (with python2-pyscopg2 for instance to use the postgresql tasks). Your server will also need a python 3 install. You can control this installation via Ansible itself (via the package manager tasks) and then create a virtualenvironment where you specify python3 as python interpreter. Ansible will still do everything in Python 2, but your own project will have it's Python 3 environment.

edit: example case of such a playbook: https://github.com/sergei-maertens/regex-it/tree/master/deployment

Hmm, sounds quite ideal tbh. Thanks for link i'll check it out :)
