Chore CI Deploy Major Tag

ParmaAI mining module for the Reddit.

Getting Started

The following steps will get you started with the project.

  1. Pre-requisites: to be able to contribute to JST in this repository, make sure to comply with the following prerequisites.

    • Configure GitHub via an ssh key. Key based authenticated is highly encouraged. See GitHub Docs for more information.
    • Please make sure to have an GPG key configured for GitHub. See GitHub Docs for more information.
    • Install micromamba, a conda environment management package manager, as described here. Alternatively conda or mamba installations should also work, but are highly discouraged because of their slow performance.

  2. Clone the repository

    git@github.com:la-famiglia-jst2324/parma-mining-reddit.git

  3. Precommit & environment setup:

    make install  # execute the last 2 steps manually!

  4. Start the api server:

    make dev

    Open http://localhost:8000 with your browser to see the result.

    FastApi will provide you with an interactive documentation of the api. You can also use the swagger ui at http://localhost:8000/docs or the redoc ui at http://localhost:8000/redoc.

  5. Optional: Running the pre-commit pipeline manually

    pre-commit run --all

  6. Test your code:

    make test

PR workflow

  1. Create a new branch linear.app offers a button to copy branch names from tickets. In case there is no ticket, please use feel free to use an arbitrary name or create a ticket. GitHub CI doesn't care about the branch name, only the PR title matters.

    # format: e.g. robinholzingr/meta-1-create-archtecture-drafts-diagrams-list-of-key-priorities
git checkout -b <branch-name>

  2. Open a PR and use a conventional commit PR title.

  3. Wait for CI pipeline to pass and if you are happy with your changes request a review.

  4. Merge the PR (using the "Squash and merge" option) and delete the branch. Pay attention to include co-authors if anyone else contributed to the PR.

  5. If you want to release a new version to production, create a new release on GitHub. The release version will be automatically derived from the PR titles (breaking changes yield new major versions, new features yield new minor versions).

Tech Stack and Dependencies

Core libraries that this project uses:

  • FastAPI: FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints.
  • Pydantic: Data validation and settings management using python type annotations.
  • Typer: Typer is a library for building CLI applications that users will love using and developers will love creating.
  • Polars: Polars is a blazingly fast data processing library written in Rust. It has a DataFrame API that is similar to Pandas and a Series API that is similar to NumPy.
  • Pytest: The pytest framework makes it easy to write small tests, yet scales to support complex functional testing for applications and libraries.
  • Python-Jose: The JavaScript Object Signing and Encryption (JOSE) technologies collectively can be used to encrypt and/or sign content using a variety of algorithms.
  • HTTPX: HTTPX is a fully featured HTTP client for Python 3, which provides sync and async APIs, and support for both HTTP/1.1 and HTTP/2.
  • PRAW: PRAW, an acronym for "Python Reddit API Wrapper", is a Python package that allows for simple access to Reddit's API. PRAW aims to be easy to use and internally follows all of Reddit's API rules.

Deployment

The deployment of Parma Mining Modules are managed through a combination of Terraform for infrastructure management and GitHub Actions for continuous integration and delivery. Our deployment strategy ensures that our application is consistently deployed across different environments with high reliability and minimal manual intervention.

Infrastructure as Code with Terraform

We use Terraform for defining, provisioning, and managing the cloud infrastructure required for Parma Mining Modules. Our Terraform configuration files are organized under the terraform directory, divided into different environments like staging (staging), and production (prod). Each environment has its own set of configurations and variables, ensuring isolation and control over different deployment stages.

A pivotal aspect of our Terraform strategy is the use of a common module, which is housed in the module directory. This module encompasses the core infrastructure components that are shared across all environments. The utilization of a shared module ensures consistency and streamlines our infrastructure management.

Each environment, staging and production, references this common module but with its own set of environment-specific configurations and variables. This structure ensures that each environment, while based on a common foundation, is independently configurable and isolated, thus providing precise control over the deployment in various stages.

The application is containerized and deployed to Google Cloud Run, providing a scalable and serverless environment for running our APIs. This is defined in service.tf.

Continuous Deployment with GitHub Actions

Our GitHub Actions workflow, defined in .github/workflows/deploy.yml, automates the deployment process. The workflow is triggered on pushes to the main branch and on published releases. It encompasses steps for:

  • Setting up the Google Cloud CLI and authenticating with Google Cloud services.
  • Building and pushing Docker images to Google Container Registry.
  • Executing Terraform commands (init, plan, apply) to deploy the infrastructure and services as per the Terraform configurations.
  • Environment-specific variables and secrets (like database passwords, API keys, etc.) are securely managed through GitHub Secrets and are injected into the deployment process as needed.

Deployment Environments

We maintain two primary environments for our application:

  • Staging (staging): A pre-production environment that closely resembles the production setup, used for final testing before a release.
  • Production (prod): The live environment where our application is available to end-users.

Module Interface

Endpoint 1: Initialize

Path: /initialize

Method: GET

Description: This endpoint initializes the module, that will be done during the handshake with Parma Analytics. It introduces data format to analytics. This process includes registering the measurements which are defined in the normalization map.

Input:

  • Type: integer
  • Content: Source id of the module

Output:

  • Type: JSON response
  • Content: Frequency of module and the normalization map of the data format.

Endpoint 2: Discovery

Path: /discover

Method: POST

Description: This endpoint allows clients to search for identifiers based on a query string. It is designed to facilitate the discovery of organizations, domains, channels etc. by keyword. For this module, this endpoint takes name of the company as parameter and returns subreddits that related with this name.

Input:

  • Type: JSON body
  • Content: A dict containing company ids and names.

Output:

  • Type: JSON response
  • Content: An object that contains information about an subreddits that matches the search query.

Endpoint 3: Get Company Details

Path: /companies

Method: POST

Description: This endpoint retrieves detailed information about a list of companies using their unique IDs and feed the collected raw data to analytics backend.

Input:

  • Type: JSON body
  • Content: A dictionary of companies and relative handles for these companies.

Output: HTTP status OK
