Nectus

Flask Boilerplate to quickly get started with production grade flask application with some additional packages and configuration prebuilt.

Getting Started

Prerequisites

• Python 3.9.2 or higher
• PostgreSQL
• Docker

Project setup

# clone the repo
$ git clone https://github.com/yezz123/Nectus.git

# move to the project folder
$ cd Nectus

Creating virtual environment

• Install pipenv a global python project pip install pipenv

• Create a virtual environment for this project

  creating pipenv environment for python 3

  $ pipenv --three

  activating the pipenv environment

  $ pipenv shell

  if you have multiple python 3 versions installed then

  $ pipenv install -d --python 3.8

  install all dependencies (include -d for installing dev dependencies)

  $ pipenv install -d

Configuration

• Create a .env file from .env.sample and set appropriate environment variables before running the project

  APP_NAME=Nectus

  DB_HOST= # Host ex. localhost
  DB_DATABASE= # Database
  DB_USERNAME= # Username ex. Root
  DB_PASSWORD= # Password

  JWT_SECRET= # generate a JWT Secret
  UPLOAD_FOLDER = public

  FLASK_APP=main.py
  FLASK_ENV=development

Database Migration

• Make sure the database name username, password and host have been set in the env

• Migrate and upgrade database into your database management (for this case postgreeSQL)

  flask db init

  flask db migrate -m "create new table"

  flask db upgrade

Running app

• If you feel that everything can be run, then run the Flash API

  flask run

Running the Docker Container

• We have the Dockerfile created in above section. Now, we will use the Dockerfile to create the image of the flask app and then start the flask app container.

  docker build

• list all the docker images and you can also see the image nectus:latest in the list.

  docker images

• run the application at port 5000. The various options used are:

• -p: publish the container's port to the host port.
• -d: run the container in the background.
• -i: run the container in interactive mode.
• -t: to allocate pseudo-TTY.
• --name: name of the container

docker container run -p 5000:5000 -dit --name Nectus nectus:latest

• Check the status of the docker container

  docker container ps
