piku-django-scale

The repository to support my presentation at Scale 21x for Piku

Installation

• Build a VM

• Install PIKU onto the VM using Piku-Bootstrap

curl https://piku.github.io/get | sh
sudo ./piku-bootstrap install piku.yml

• Back on the client, Grab the repo, setup PIPENV and add piku user to remote GIT repo

git clone https://github.com/jfmatth/piku-django-scale.git
cd piku-django-scale
pipenv shell
pipenv update
git remote add piku piku@server:appname

Test local version

Django app

python manage.py migrate
python manage.py runserver

browse to http://127.0.0.1:8000 to test

Push code to piku and GIT hooks

git push piku

You'll need to use a git feature called hooks that rebuilds the requirements.txt file on a commit, since Pipenv doesn't create one automatically.

In the file .git/pre-commit, add the following code

#!/bin/bash

# Generate requirements.txt from Pipfile
pipenv sync
pipenv requirements > requirements.txt

# Add requirements.txt to the commit
git add requirements.txt

Configure environment

piku run -- python manage.py migrate --no-input
piku config:set NGINX_SERVER_NAME=<your FQDN of site and server>
