Developer Operations for Nighthawk Students and Infrastructure

• WIP Admin Server
• Terraform Automation Plan

Primary way to get started

Quick steps that can be used with MacOS or WSL; this uses Python 3.9 or later as a prerequisite.

• Open a Terminal, clone project and cd to project area

mkdir ~/vscode; cd ~/vscode

git clone https://github.com/nighthawkcoders/devOps.git devops

cd devops

• Install python dependencies for Flask, etc.

pip install -r requirements.txt

• Run from Terminal without VSCode

  • Run python from command line and check server

  python main.py

• Prepare VSCode and run

  • From Terminal run VSCode

  code .

Idea

The purpose of project is to serve APIs for managing Student and Classroom data. It is the backend piece of a Full-Stack project. There may be many frontend companions to the project, based off of year and curriculum.

History of Project, see Terraform Automation Plan

Building Student Desktop workspaces in the cloud

• Infrastructure: AWS, Kasm Workspaces
• Tooling: Python, Terraform, AWS CLI, Python BOTO module, Kasm Developer API
• SQL Database: User Database and APIs

Database Migration

In case of Schema change it is important to upgrade database as follows.

• Install flask app

export FLASK_APP=main
export PYTHONPATH=.:$PYTHONPATH  # flask need . to find files
flask db init
flask db upgrade

• It may be easiest to have a Docker file to do this on production environment. We should backup database before schema upgrade

ENV FLASK_APP=main
ENV PYTHONPATH=.:$PYTHONPATH
RUN flask db init
RUN flask db upgrade

Scripts

Creating AWS Users

• GET /create_users, it will create AWS users from the GH ids in database if they don't exist

Updating KASM servers in datbaase

• GET /update_users_kasm, it will find the KASM server for each user in the database and update their DB Entry

Migrating Database

• ./migrate.sh
