## 🎯 What is DevOps? (Simple Explanation)

**DevOps = Development + Operations**

Instead of:
1. Write code → 2. Manually test → 3. Manually deploy → 4. Hope it works

**DevOps automates:**
1. Write code → 2. **Auto-test** → 3. **Auto-deploy** → 4. **Auto-monitor**

**Key Concept:** If you do something more than once, automate it!

## 🚀 DevOps Best Practices (2025) - Beginner Edition

### Practice 1: **Commit Code Frequently** ✅ (You already do this!)

**What:** Small, frequent commits instead of large, infrequent ones

**Why:** Easier to find bugs, easier to collaborate, less scary to deploy

**You already have:** `commit-commands` plugin for smart commits

**Keep doing:**
```bash
# Your current workflow (excellent!)
git add .
git commit -m "descriptive message"
git push
```

### Practice 2: **Automate Testing** ⭐ (HIGH PRIORITY)

**What:** Tests run automatically on every commit/PR

**Why:** Catch bugs before they reach production

**Your current state:** Tests exist (pytest, R CMD check) but manual

**Action needed:**
1. Set up GitHub Actions to run tests automatically
2. Use `devops-automation` plugin to create workflows
3. Tests run on: every commit, every PR, before release

**Example GitHub Action** (we'll create this):
```yaml
name: Run Tests
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
      - run: pytest
```

### Practice 3: **Build Once, Deploy Many** ⭐

**What:** Build your package/docs once, deploy to multiple places

**Why:** Consistency, speed, reliability

**Your use cases:**
- R packages: Build → Test → Deploy to CRAN
- Documentation: Build → Deploy to GitHub Pages
- Python tools: Build → Deploy to PyPI

**We'll set this up!**

### Practice 4: **Integrate Security Early (DevSecOps)** ⭐

**What:** Check for security issues automatically

**Why:** Prevent vulnerabilities from reaching production

**Tools for you:**
- GitHub CodeQL (free for public repos)
- Dependabot (auto-update dependencies)
- `code-review` plugin (you have it!)

**Action:** Enable CodeQL in GitHub Actions

### Practice 5: **Monitor Everything**

**What:** Know when things break, before users complain

**Why:** Faster fixes, happier users

**Your use case:**
- Monitor aiterm installation success rate
- Monitor documentation site uptime
- Monitor CRAN package status

**Tool:** `infrastructure-maintainer` plugin (you have it!)

### Practice 6: **Automate Documentation Deployment** ✅

**What:** Docs auto-deploy when you update code

**Why:** Docs always up-to-date, zero manual work

**Your current setup:**
- MkDocs for Python projects ✅
- Pkgdown for R packages ✅
- Quarto for research/teaching ✅

**Need:** GitHub Actions to auto-deploy (we'll set up!)

   The project uses uv for dependency management."
   ```

2. **Save the workflow:**
   - Plugin will generate `.github/workflows/test.yml`
   - Review it (I'll explain what each part does!)
   - Commit it

3. **Push and watch:**
   - Push to GitHub
   - Go to Actions tab
   - Watch your first automated test run! 🎉

4. **Celebrate!**
   - Green checkmark = dopamine
   - You just automated something!
   - You're doing DevOps!

## 💡 DevOps Mindset for ADHD Brains

### Principle 1: **Automate the Boring Stuff** ⭐⭐⭐

If you've done it twice, automate it the third time.

**Examples:**
- Running tests before commit → Automate with pre-commit hooks
- Deploying docs → Automate with GitHub Actions
- Checking code style → Automate with linters

### Principle 2: **Quick Wins Build Momentum**

Start with easiest automation, build confidence, tackle harder ones.

**Your progression:**
1. ✅ Week 1: Automated tests (easy, high value)
2. ✅ Week 2: Automated docs (easy, visible)
3. ✅ Week 3: Security (easy, important)
4. ✅ Week 4: R packages (harder, huge value)

### Principle 3: **Dopamine from Green Checkmarks**

Every passing CI build is a dopamine hit!

**Optimization:**
- Keep tests fast (< 5 min)
- See results immediately
- Green = good, red = fix and get green!

### Principle 4: **Fail Fast, Fix Fast**

Catch problems early = easier fixes

**Your safety net:**
- Tests catch bugs before deployment
- Security scans catch vulnerabilities
- Automated checks catch style issues
