Python DevOps

This repo will contain any references to deploy APIs with Python (FastAPI/Django/Flask) using the following: Vagrant, Docker containers, or AWS (Lambda, Gateway, Serverless, torchserve via PyTorch).

Contents:

1. Setup Environment Commands	2. Profile API (Django)
3. Hello world (FastAPI)	4. PyTorch Image model (Flask)

Vagrant Setup

Make sure you have the following commands setup on ur API project
(1) Create a configuration file Vagrantfile with server support (ubuntu/bionic64). Somtimes you will need to edit the Vagrantfile in order to setup step (2) properly.

vagrant init ubuntu/bionic64

(2) Download the base image specified inside VagrantFile configuration then start a virtual machine setup with ubuntu server.

vagrant up 

(3) Connect to vagrant server as a 'guest' which is why we use the ssh flag on our command. Ubuntu commands are not the same as windows or mac.

vagrant ssh

(4) exit --> If you ever wish to exit the development server and back to you're local machine.

Vagrant Tips

(0) Make sure you change directories to the path '/vagrant' inside of the virtua ubuntu.
(1) Development repo is under the folder /vagrant using the command 'cd /vagrant'
(2) Create python environment onto server.

python -m venv ~/env

(3) Activate virtual env

source ~/env/bin/activate

(4) Deactivate virtual environment.

deactivate

Dependency (install inside vagrant env activated)

pip install -r requirements.txt </br>

Django Admin Setip

(1) the script (django-admin.py) is passed in and the argument "startproject" is a flag to start a new project (profiles_project). the "." is an optional argument to place the folder on the root of invoked command.

django-admin.py startproject profiles_project .  

is passed in and the argument "startproject" is
a flag to start a new project (profiles_project).
the "." is an optional argument to place the folder on the root of invoked command.
(2) Start a new django api project using manage.py

python manage.py startapp [name]

(3) Inside of settings.py, repo inside of django api project from step (2), add in the following apps
(4) On the browser type in 'http://127.0.0.1:8000/' to view ur code on the server. Django place holder (img of a rocket) is set to default.

python manage.py runserver 0.0.0.0:8000

(4a) If running the local host ends up in an infinite loop.

python manage.py runserver --noreload 0.0.0.0:8000 

Django Migration setup

These two can create an init file (0001_initial.py)

python manage.py migrate
python manage.py makemigrations [name: profiles_api] 

Django Create superuser

python manage.py createsuperuser
