# Pipeline Examples for AZ-400 Training
2+
3+
This directory contains verified YAML pipeline examples for teaching CI/CD concepts in the AZ-400 course.
4+
5+
## 📁 Pipeline Files
6+
7+
### 1. Single-Stage CI Pipeline (`single-stage-ci.yml`)
8+
**Purpose:** Basic continuous integration for Node.js applications
9+
10+
**Key Features:**
11+
- Node.js setup and dependency installation
12+
- Linting and code quality checks
13+
- Unit testing with coverage
14+
- Artifact creation and publishing
15+
- Clear commenting for learning
16+
17+
**Use Case:** Teaching CI fundamentals in Segment 2
18+
19+
### 2. Multi-Stage CI/CD Pipeline (`multi-stage-cicd.yml`)
20+
**Purpose:** Complete DevOps pipeline with multiple environments
21+
22+
**Key Features:**
23+
- 5 stages: Build → Dev → Staging → Production → Post-Deploy
24+
- Environment approvals and gates
25+
- Blue-green deployment strategy
26+
- Automated rollback on failure
27+
- Performance and integration testing
28+
- Deployment slots and swapping
29+
30+
**Use Case:** Advanced pipeline concepts in Segment 3
31+
32+
### 3. GitHub Actions Workflow (`../.github/workflows/node-azure-deploy.yml`)
33+
**Purpose:** GitHub-native CI/CD to Azure
34+
35+
**Key Features:**
36+
- Matrix strategy for multiple Node versions
37+
- GitHub environments with protection rules
38+
- Azure Web App deployment
39+
- Release tagging
40+
- Security scanning with CodeQL
41+
- Reusable workflow patterns
42+
43+
**Use Case:** Comparing Azure Pipelines vs GitHub Actions
44+
45+
## 🚀 How to Use These Examples
46+
47+
### For Azure Pipelines:
48+
1. Create a new pipeline in Azure DevOps
49+
2. Select "Existing Azure Pipelines YAML file"
50+
3. Choose the appropriate YAML file
51+
4. Update variables (service connections, resource names)
52+
5. Save and run
53+
54+
### For GitHub Actions:
55+
1. Workflow is automatically detected in `.github/workflows/`
56+
2. Configure secrets in repository settings:
57+
- `AZURE_CREDENTIALS` - Service principal JSON
58+
3. Workflow triggers on push to main/master
59+
60+
## 📝 Required Configuration
61+
62+
### Azure Resources:
63+
```bash
64+
# Create resource group
65+
az group create --name rg-az400-demo --location eastus
66+
67+
# Create App Service Plan
68+
az appservice plan create \
69+
--name plan-az400-demo \
70+
--resource-group rg-az400-demo \
71+
--sku B1 \
72+
--is-linux
73+
74+
# Create Web Apps
75+
az webapp create \
76+
--name webapp-az400-demo-dev \
77+
--resource-group rg-az400-demo \
78+
--plan plan-az400-demo \
79+
--runtime "NODE:18-lts"
80+
```
81+
82+
### Service Connection (Azure DevOps):
83+
1. Project Settings → Service connections
84+
2. New service connection → Azure Resource Manager
85+
3. Service principal (automatic)
86+
4. Name: `AZ400-ServiceConnection`
87+
88+
### GitHub Secrets:
89+
```bash
90+
# Create service principal
91+
az ad sp create-for-rbac \
92+
--name "sp-az400-github" \
93+
--role contributor \
94+
--scopes /subscriptions/{subscription-id}/resourceGroups/rg-az400-demo \
95+
--json-auth
96+
```
97+
98+
## 🎓 Teaching Points
99+
100+
### Single-Stage Pipeline:
101+
- Pipeline triggers and paths
102+
- Agent pools and VM images
103+
- Variables and expressions
104+
- Task vs script steps
105+
- Artifact publishing
106+
107+
### Multi-Stage Pipeline:
108+
- Stage dependencies
109+
- Deployment jobs vs regular jobs
110+
- Environment approvals
111+
- Deployment strategies
112+
- Failure handling
113+
114+
### GitHub Actions:
115+
- Workflow syntax differences
116+
- Actions marketplace
117+
- Environments and secrets
118+
- Reusable workflows
119+
- GitHub-specific features
120+
121+
## 🔧 Customization
122+
123+
Students can modify these pipelines to:
124+
- Add additional testing frameworks
125+
- Implement different deployment strategies
126+
- Add notifications (Teams, Slack)
127+
- Include infrastructure as code
128+
- Add security scanning tools
129+
130+
