CI/CD Automation Setup Guide

CI/CD Automation Setup Guide

Summary

A complete GitHub Actions CI/CD pipeline has been created for the bankole.org Jekyll blog. The pipeline automatically validates code quality, builds the site, and performs performance audits on every commit.

Files Created

1. Workflow Configuration

Location: .github/workflows/ci.yml Size: 2.8 KB Purpose: Main GitHub Actions workflow definition Status: Ready to use

2. Markdown Linting Configuration

Location: .markdownlint.json Size: 480 bytes Purpose: Enforces markdown formatting standards Settings:

3. Lighthouse Configuration

Location: lighthouserc.json Size: 610 bytes Purpose: Defines performance audit targets Settings:

What the Pipeline Does

Automatically Runs On:

Validation Steps (Sequential)

1. Tests Job (~2 minutes)

Status: Blocking (must pass)

Validates:

Requirements: All tests must pass

2. Build Job (~3 minutes)

Status: Blocking (must pass) Depends On: Tests passing

Builds:

Output: Site artifacts stored for 5 days

3. Lighthouse Audit (~2 minutes)

Status: Non-blocking (informational) Depends On: Build succeeding

Measures:

Output: Performance report with scores

4. SEO & Accessibility (~1 minute)

Status: Non-blocking (informational) Depends On: Build succeeding

Checks:

Output: Detailed violation reports

How to Use

Customization

Change Line Length

Edit .markdownlint.json:

"MD013": {
  "line_length": 120
}

Adjust Performance Targets

Edit lighthouserc.json:

"categories:performance": ["error", { "minScore": 0.80 }]

Add New Test Steps

Edit .github/workflows/ci.yml:

- name: New test

Troubleshooting

Tests Fail

Solution: Run locally to debug

node tests/performance-tests.js
bash tests/validate-assets.sh

Build Fails

Causes: Jekyll config error, front matter syntax Solution:

Markdown Lint Fails

Cause: Line too long or formatting issue Solution:

Cause: Broken markdown references Solution:

Lighthouse Low Score

Cause: Large images, blocking resources Solution:
