CI/CD Deployment

Current Status of CI/CD

As of now, the project does not have a CI/CD setup. Below are the recommended next steps to implement CI/CD for the project using Docker and related technologies.

Next Steps for CI/CD Setup

1. Choose a CI/CD Platform: Select a CI/CD tool (e.g., GitHub Actions, GitLab CI, CircleCI, Travis CI, etc.).

2. Create Configuration File for CI/CD: Depending on the chosen platform, create a configuration file to define the CI/CD pipeline. Below is an example for a hypothetical GitHub Actions setup:

   # .github/workflows/ci.yml
   name: CI
   
   on:
     push:
       branches:
         - main
     pull_request:
     workflow_dispatch:
   
   jobs:
     build:
       runs-on: ubuntu-latest
     
       steps:
       - name: Check out code
         uses: actions/checkout@v2
   
       - name: Set up Python
         uses: actions/setup-python@v2
         with:
           python-version: '3.12'
   
       - name: Install dependencies
         run: |
           python -m pip install --upgrade pip
           pip install .[ssh]
   
       - name: Run tests
         run: |
           make test
   

3. Use Docker for Isolation: Integrate Docker within the CI/CD pipeline to provide consistent and isolated environments. Modify the CI/CD configuration to build and run tests within Docker.

   jobs:
     build:
       runs-on: ubuntu-latest
     
       steps:
       - name: Check out code
         uses: actions/checkout@v2
   
       - name: Build Docker Image
         run: |
           docker build -t my-app .
   
       - name: Run Tests
         run: |
           docker run --rm my-app make test
   

4. Create Docker Image: The Dockerfile facilitates image creation. Ensure that the Dockerfile is set up as follows:

   # syntax=docker/dockerfile:1
   
   ARG PYTHON_VERSION=3.12
   FROM python:${PYTHON_VERSION}
   
   WORKDIR /src
   COPY . .
   
   ARG VERSION=0.0.0.dev0
   RUN --mount=type=cache,target=/cache/pip \
       PIP_CACHE_DIR=/cache/pip \
       SETUPTOOLS_SCM_PRETEND_VERSION=${VERSION} \
       pip install .[ssh]
   

5. Define Testing Commands in Makefile: Implement commands in the Makefile for unit and integration tests as part of the CI/CD process.

   .PHONY: test unit-test integration-test
   
   test: unit-test integration-test
   
   unit-test:
       # Command for unit tests
       pytest tests/unit
   
   integration-test:
       # Command for integration tests
       pytest tests/integration
   

6. Deploy After Successful Tests: After successful tests, configure the pipeline to deploy the application. This might include pushing the Docker image to a container registry and deploying to the desired environment.

   deploy:
     runs-on: ubuntu-latest
     needs: build
     
     steps:
     - name: Deploy to Docker Hub
       run: |
         echo "${{ secrets.DOCKER_HUB_PASSWORD }}" | docker login -u "${{ secrets.DOCKER_HUB_USERNAME }}" --password-stdin
         docker tag my-app my-docker-user/my-app:latest
         docker push my-docker-user/my-app:latest
   

Conclusion

Following these steps will guide you in setting up CI/CD for your project using Docker and integrate testing and deployment processes effectively. As the CI/CD process evolves, make adjustments based on project requirements and team workflows.
