Overview

The sourcegraph/zoekt project currently does not have a CI/CD workflow established. Below are suggested next steps to set up an effective CI/CD pipeline for this project. This guidance aims to provide a structured approach for expert developers looking to implement continuous integration and delivery processes.

Next Steps for Setting Up CI/CD

  1. Define CI/CD Requirements: Determine the goals of the CI/CD pipeline including build goals, testing requirements, and deployment strategies.

  2. Choose a CI/CD System: Select a CI/CD tool that fits the project’s needs, such as GitHub Actions, GitLab CI, CircleCI, or Jenkins.

  3. Create Configuration Files: Based on the chosen CI/CD tool, create the necessary configuration files to define the build and deployment processes.

Example CI Configuration

Below is an example of a configuration file using GitHub Actions that could be used in the .github/workflows/ci.yml file:

name: CI

on:
  push:
    branches:
      - main
  pull_request:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout Code
      uses: actions/checkout@v2
      
    - name: Set up Go
      uses: actions/setup-go@v2
      with:
        go-version: '1.22.2'
    
    - name: Install Dependencies
      run: |
        go mod download

    - name: Build Binary
      run: |
        go install -ldflags "-X github.com/sourcegraph/zoekt.Version=${{ github.sha }}" ./cmd/...

    - name: Run Tests
      run: |
        go test ./...

Explanation of Steps

  • Checkout Code: This step checks out the code from the repository to the runner.

  • Set up Go: This installs the specific version of Go required for the project.

  • Install Dependencies: The go mod download command downloads the dependencies specified in go.mod.

  • Build Binary: This step compiles the Go project while embedding the current commit SHA in the binary using -ldflags.

  • Run Tests: Executes the test suite to ensure the code functions as expected.

Continuous Delivery

Once a CI pipeline is established, consider extending the workflow to include steps for continuous delivery:

Example Continuous Delivery Configuration

The following snippet could be added to the same GitHub Actions file to deploy on successful builds.

  deploy:
    runs-on: ubuntu-latest
    needs: build
    steps:
    - name: Deploy to Production
      env:
        DEPLOY_TOKEN: ${{ secrets.DEPLOY_TOKEN }}
      run: |
        # Add your deployment commands here, for example, using Docker
        docker build -t your-docker-image:latest .
        echo "${DEPLOY_TOKEN}" | docker login -u your-username --password-stdin
        docker push your-docker-image:latest

Explanation of Deployment Steps

  • Needs: Specifies that this job depends on the successful completion of the build job.

  • Deploy Token: Securely retrieves a deployment token from secrets.

  • Deployment Commands: Builds the Docker image and pushes it to a Docker registry.

Conclusion

Setting up a CI/CD workflow for the sourcegraph/zoekt project involves defining requirements, selecting a CI/CD tool, and creating configurations tailored to the project’s needs. The examples provided aim to guide expert developers through the initial stages of CI/CD implementation. Further enhancements can include automated deployments, monitoring, and scaling strategies tailored to the project’s evolution.
