# Azure App Service Deployment - Stap-voor-Stap Guide 🚀

Complete deployment guide voor CMDB Insight naar Azure App Service.

## 🎯 Waarom Azure App Service?

Azure App Service is de aanbevolen deployment optie voor CMDB Insight omdat:

1. **Managed Service** ⭐
   - Geen serverbeheer, SSH, Linux configuratie nodig
   - Azure beheert alles (updates, security patches, scaling)
   - Perfect voor teams die geen infrastructuur willen beheren

2. **Eenvoudig & Snel**
   - Setup in ~15 minuten
   - Automatische SSL/TLS certificaten
   - Integratie met Azure DevOps pipelines

3. **Kosten-Effectief**
   - Basic B1 plan: ~€15-25/maand
   - Voldoende voor 20 gebruikers
   - Geen verborgen kosten

4. **Flexibel**
   - Deployment slots voor testen (staging → productie)
   - Eenvoudige rollback
   - Integratie met Azure Key Vault voor secrets

5. **Monitoring & Compliance**
   - Integratie met Azure Monitor
   - Logging en audit trails (NEN 7510 compliance)
   - Health checks ingebouwd

**Geschatte kosten:** ~€20-25/maand (met PostgreSQL database)

## 📋 Prerequisites

- Azure CLI geïnstalleerd en geconfigureerd (`az login`)
- Docker images in ACR: `zdlasacr.azurecr.io/cmdb-insight/backend:latest` en `frontend:latest`
- Azure DevOps pipeline werkt (images worden automatisch gebouwd)

## 🎯 Quick Start (15 minuten)

### Stap 1: Resource Group

```bash
az group create \
  --name zdl-cmdb-insight-prd-euwe-rg \
  --location westeurope
```

### Stap 2: App Service Plan

```bash
az appservice plan create \
  --name zdl-cmdb-insight-prd-euwe-appsvc \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --sku B1 \
  --is-linux
```

### Stap 3: Web Apps

```bash
# Backend
az webapp create \
  --name zdl-cmdb-insight-prd-backend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --plan zdl-cmdb-insight-prd-euwe-appsvc \
  --container-image-name zdlasacr.azurecr.io/cmdb-insight/backend:latest

# Frontend
az webapp create \
  --name zdl-cmdb-insight-prd-frontend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --plan zdl-cmdb-insight-prd-euwe-appsvc \
  --container-image-name zdlasacr.azurecr.io/cmdb-insight/frontend:latest
```

### Stap 4: ACR Authentication

```bash
# Enable Managed Identity
az webapp identity assign --name zdl-cmdb-insight-prd-backend-webapp --resource-group zdl-cmdb-insight-prd-euwe-rg
az webapp identity assign --name zdl-cmdb-insight-prd-frontend-webapp --resource-group zdl-cmdb-insight-prd-euwe-rg

# Get Principal IDs
BACKEND_PRINCIPAL_ID=$(az webapp identity show \
  --name zdl-cmdb-insight-prd-backend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --query principalId -o tsv)
FRONTEND_PRINCIPAL_ID=$(az webapp identity show \
  --name zdl-cmdb-insight-prd-frontend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --query principalId -o tsv)

# Get ACR Resource ID
ACR_ID=$(az acr show --name zdlasacr --query id -o tsv)

# Grant AcrPull permissions
az role assignment create --assignee $BACKEND_PRINCIPAL_ID --role AcrPull --scope $ACR_ID
az role assignment create --assignee $FRONTEND_PRINCIPAL_ID --role AcrPull --scope $ACR_ID

# Configure container settings
az webapp config container set \
  --name zdl-cmdb-insight-prd-backend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --docker-registry-server-url https://zdlasacr.azurecr.io

az webapp config container set \
  --name zdl-cmdb-insight-prd-frontend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --docker-registry-server-url https://zdlasacr.azurecr.io
```

### Stap 5: PostgreSQL Database Setup (Aanbevolen voor Productie)

**Voor PostgreSQL setup, zie:** `docs/AZURE-POSTGRESQL-SETUP.md`

**Quick setup met script:**
```bash
./scripts/setup-postgresql.sh
```

**Of handmatig:**
```bash
# Maak PostgreSQL Flexible Server aan
az postgres flexible-server create \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --name zdl-cmdb-insight-prd-psql \
  --location westeurope \
  --admin-user cmdbadmin \
  --admin-password $(openssl rand -base64 32) \
  --sku-name Standard_B1ms \
  --tier Burstable \
  --storage-size 32 \
  --version 15

# Maak database aan (één database is voldoende)
az postgres flexible-server db create \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --server-name zdl-cmdb-insight-prd-psql \
  --database-name cmdb_insight
```

**Voor SQLite (alternatief, eenvoudiger maar minder geschikt voor productie):**
- Geen extra setup nodig
- Database wordt automatisch aangemaakt in container
- Zie Stap 5b hieronder

### Stap 5a: Environment Variabelen met PostgreSQL

```bash
# Backend met PostgreSQL (vervang met jouw waarden)
az webapp config appsettings set \
  --name zdl-cmdb-insight-prd-backend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --settings \
    NODE_ENV=production \

## 🔐 Azure Key Vault Setup (Aanbevolen)

Voor productie: gebruik Azure Key Vault voor secrets.

### Stap 1: Key Vault Aanmaken

```bash
az keyvault create \
  --name kv-cmdb-insight-prod \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --location westeurope \
  --sku standard
```

### Stap 2: Secrets Toevoegen

```bash
az keyvault secret set --vault-name kv-cmdb-insight-prod --name JiraPat --value "your-token"
az keyvault secret set --vault-name kv-cmdb-insight-prod --name SessionSecret --value "$(openssl rand -hex 32)"
az keyvault secret set --vault-name kv-cmdb-insight-prod --name JiraSchemaId --value "your-schema-id"
```

### Stap 3: Grant Access

**Voor Key Vault met RBAC authorization (aanbevolen):**

```bash
# Get Key Vault Resource ID
KV_ID=$(az keyvault show --name zdl-cmdb-insight-prd-kv --query id -o tsv)

# Grant Key Vault Secrets User role to backend
az role assignment create \
  --assignee $BACKEND_PRINCIPAL_ID \
  --role "Key Vault Secrets User" \
  --scope $KV_ID

# Grant to frontend (if needed)
az role assignment create \
  --assignee $FRONTEND_PRINCIPAL_ID \
  --role "Key Vault Secrets User" \
  --scope $KV_ID
```

**Voor Key Vault met Access Policies (oude methode):**

```bash
az keyvault set-policy \
  --name zdl-cmdb-insight-prd-kv \
  --object-id $BACKEND_PRINCIPAL_ID \
  --secret-permissions get list
```

**Let op:** Als je de fout krijgt "Cannot set policies to a vault with '--enable-rbac-authorization'", gebruik dan de RBAC methode hierboven.

### Stap 4: Configure App Settings met Key Vault References

```bash
az webapp config appsettings set \
  --name zdl-cmdb-insight-prd-backend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --settings \
    JIRA_PAT="@Microsoft.KeyVault(SecretUri=https://kv-cmdb-insight-prod.vault.azure.net/secrets/JiraPat/)" \
    SESSION_SECRET="@Microsoft.KeyVault(SecretUri=https://kv-cmdb-insight-prod.vault.azure.net/secrets/SessionSecret/)" \
    JIRA_SCHEMA_ID="@Microsoft.KeyVault(SecretUri=https://kv-cmdb-insight-prod.vault.azure.net/secrets/JiraSchemaId/)"
```

## 📊 Monitoring Setup

### Application Insights

```bash
# Create Application Insights
az monitor app-insights component create \
  --app cmdb-insight-prod \
  --location westeurope \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --application-type web

# Get Instrumentation Key
INSTRUMENTATION_KEY=$(az monitor app-insights component show \
  --app cmdb-insight-prod \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --query instrumentationKey -o tsv)

# Configure App Settings
az webapp config appsettings set \
  --name zdl-cmdb-insight-prd-backend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --settings \
    APPINSIGHTS_INSTRUMENTATIONKEY=$INSTRUMENTATION_KEY
```

## 🔄 Updates Deployen

### Optie 1: Manual (Eenvoudig)

```bash
# Restart Web Apps (pull nieuwe latest image)
az webapp restart --name zdl-cmdb-insight-prd-backend-webapp --resource-group zdl-cmdb-insight-prd-euwe-rg
az webapp restart --name zdl-cmdb-insight-prd-frontend-webapp --resource-group zdl-cmdb-insight-prd-euwe-rg
```

### Optie 2: Deployment Slots (Zero-Downtime)

```bash
# Create staging slot
az webapp deployment slot create \
  --name zdl-cmdb-insight-prd-backend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --slot staging

# Deploy to staging
az webapp deployment slot swap \
  --name zdl-cmdb-insight-prd-backend-webapp \
  --resource-group zdl-cmdb-insight-prd-euwe-rg \
  --slot staging \
  --target-slot production
```
