How To Serve Flask Applications with uWSGI and Nginx on Ubuntu 14.04

@credit Yan Zhu (https://github.com/nina-zhu)

Introduction

Flask is a microframework for Python based on Werkzeug, Jinja 2 and good intentions, it can help you get your Python application or website off the ground. Flask includes a simplified development server for testing your code locally, but for anything even slightly production related, a more secure and powerful web server is required.

In this guide, we will demonstrate how to install and configure some components on Ubuntu 14.04 to support and serve Flask applications. We will configure the uWSGI application container server to interface with our applications. We will then set up Nginx to reverse proxy to uWSGI, giving us access to its security and performance features to serve our apps.

Prerequisites and Goals

I borrowed heavily from http://blog.shupp.org/2012/08/12/local-timezone-lookups-by-coordinates-with-postgis/ to make # this gist which is geared towards mac users like myself.

Step 1: Prepare to Install Postgresql & Postgis + dependencies using brew

$ brew update

NOTE: if it fails, try this

$ cd /usr/local/Library/Formula

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Assuming this table definition:

CREATE TABLE segments (segments_id serial PRIMARY KEY, payload jsonb);
With JSON values like this:

INSERT INTO segments (payload)
VALUES ('{
     "a": [
        {

"kind": "person",

	FROM python:3 as build-system

	RUN pip install -U pip

	COPY requirements.txt requirements.txt

	### create temporary image used to download and vendor packages using private key ###
	FROM build-system as intermediate

	# add credentials on build

	"""
	Usage example:

	from logger import get_logger
	log = get_logger()
	log.info('my_event', my_key1='val 1', my_key2=5, my_key3=[1, 2, 3], my_key4={'a': 1, 'b': 2})

	List of metadata keys in each log message:
	event
	_func

	package main

	import (
	"fmt"
	"time"
	"golang.org/x/sync/errgroup"
	"context"
	"os"
	"syscall"
	"os/signal"

	require 'pry'

	# ```
	# 1 => I
	# 10 => X
	# 7 => VII
	# ```

	# There is no need to be able to convert numbers larger than about 3000. (The Romans themselves didn't tend to go any higher)


	FILE SPACING:

	# double space a file
	sed G

	# double space a file which already has blank lines in it. Output file
	# should contain no more than one blank line between lines of text.
	sed '/^$/d;G'

	#!/bin/sh
	docker images --format '{{.Size}}\t{{.Repository}}\t{{.Tag}}\t{{.ID}}' \| sed 's/ //' \| sort -h -r \| column -t
