Continuous Integration and Deployment (CI/CD) for HelixML

This documentation provides an overview of the CI/CD processes used in the HelixML project, including automated testing, building, and deployment of the application.

What is CI/CD and Deployment?

CI/CD (Continuous Integration and Continuous Deployment) is a software development practice that emphasizes automating the building, testing, and deployment of code changes. This approach allows teams to frequently deliver updates to their applications, reducing the time it takes to fix bugs and add new features.

In the context of HelixML, CI/CD refers to the automated workflows that build, test, and deploy changes to the project. This includes:

  • Continuous Integration (CI): The process of automatically building and testing code changes as they are submitted to the project.
  • Continuous Deployment (CD): The process of automatically deploying tested code changes to production.

Why is CI/CD and Deployment important?

CI/CD is important for several reasons:

  1. Faster feedback: By automating the build, test, and deployment processes, teams can quickly identify and address issues with their code.
  2. Reduced risk: Automated testing and deployment help to reduce the risk of introducing bugs or other issues into the production environment.
  3. Improved collaboration: CI/CD allows multiple team members to work on the same codebase simultaneously, improving collaboration and reducing conflicts.
  4. Faster time to market: By automating the deployment process, teams can release new features and updates more quickly, reducing time to market.

HelixML’s CI/CD Setup

HelixML uses several tools to implement its CI/CD workflows. These include:

  • GitHub: The project is hosted on GitHub, which provides the source control management system and the platform for automated builds and deployments.
  • Travis CI: Travis CI is the continuous integration service used by HelixML. It automatically builds and tests code changes as they are submitted to the project.
  • CircleCI: CircleCI is the continuous deployment service used by HelixML. It automatically deploys tested code changes to production.

Continuous Integration (CI)

HelixML uses Travis CI for continuous integration. Whenever a pull request is opened or a new commit is pushed to the master branch, Travis CI automatically builds and tests the code. If the build and tests are successful, the pull request can be merged into the master branch.

# .travis.yml file in HelixML project
          language: python
          python: 3.8
          install: pip install -r requirements.txt
          script: pytest

Continuous Deployment (CD)

HelixML uses CircleCI for continuous deployment. Once the code has been built and tested on Travis CI, CircleCI automatically deploys the code to production.

# circle.yml file in HelixML project
          version: 2.1
          jobs:
            build:
              docker:
                - image: circleci/python:3.8
                  environment:
                    NODE_ENV: production
              steps:
                - checkout
                - run: pip install -r requirements.txt

                - run: gunicorn --config production.conf wsgi:application
          
            test:
              docker:

              steps:

                - run: python manage.py test

                      branches:

                    requires:
                      - build
                      - test
