FRONTEND_PRINCIPAL_ID=$(az webapp identity show --name cmdb-frontend-prod --resource-group rg-cmdb-gui-prod --query principalId -o tsv)

# Get ACR Resource ID (vervang <acr-resource-group> met jouw ACR resource group)
ACR_ID=$(az acr show --name zdlas --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 cmdb-backend-prod \
  --resource-group rg-cmdb-gui-prod \
  --docker-custom-image-name zdlas.azurecr.io/cmdb-insight/backend:latest \
  --docker-registry-server-url https://zdlas.azurecr.io

az webapp config container set \
  --name cmdb-frontend-prod \
  --resource-group rg-cmdb-gui-prod \
  --docker-custom-image-name zdlas.azurecr.io/cmdb-insight/frontend:latest \
  --docker-registry-server-url https://zdlas.azurecr.io
```

### Stap 5: Environment Variabelen

```bash
# Backend (vervang met jouw waarden)
az webapp config appsettings set \
  --name cmdb-backend-prod \
  --resource-group rg-cmdb-gui-prod \
  --settings \
    NODE_ENV=production \
    PORT=3001 \
    JIRA_BASE_URL=https://jira.zuyderland.nl \
    JIRA_SCHEMA_ID=your-schema-id \
    JIRA_PAT=your-pat-token \
    SESSION_SECRET=$(openssl rand -hex 32) \
    FRONTEND_URL=https://cmdb-frontend-prod.azurewebsites.net

# Frontend
az webapp config appsettings set \
  --name cmdb-frontend-prod \
  --resource-group rg-cmdb-gui-prod \
  --settings \
    VITE_API_URL=https://cmdb-backend-prod.azurewebsites.net/api
```

### Stap 6: Start Apps

```bash
az webapp start --name cmdb-backend-prod --resource-group rg-cmdb-gui-prod
az webapp start --name cmdb-frontend-prod --resource-group rg-cmdb-gui-prod
```

### Stap 7: Test

```bash
# Health check
curl https://cmdb-backend-prod.azurewebsites.net/api/health

# Frontend
curl https://cmdb-frontend-prod.azurewebsites.net
```

## 🔐 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-gui-prod \
  --resource-group rg-cmdb-gui-prod \
  --location westeurope \
  --sku standard
```

### Stap 2: Secrets Toevoegen

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

### Stap 3: Grant Access

```bash
az keyvault set-policy \
  --name kv-cmdb-gui-prod \
  --object-id $BACKEND_PRINCIPAL_ID \
  --secret-permissions get list
```

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

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

## 📊 Monitoring Setup

### Application Insights

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

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

# Configure App Settings
az webapp config appsettings set \
  --name cmdb-backend-prod \
  --resource-group rg-cmdb-gui-prod \
  --settings \
    APPINSIGHTS_INSTRUMENTATIONKEY=$INSTRUMENTATION_KEY
```

## 🔄 Updates Deployen

### Optie 1: Manual (Eenvoudig)

```bash
# Restart Web Apps (pull nieuwe latest image)
az webapp restart --name cmdb-backend-prod --resource-group rg-cmdb-gui-prod
az webapp restart --name cmdb-frontend-prod --resource-group rg-cmdb-gui-prod
```

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

```bash
# Create staging slot
az webapp deployment slot create \
  --name cmdb-backend-prod \
  --resource-group rg-cmdb-gui-prod \
  --slot staging

# Deploy to staging
az webapp deployment slot swap \
  --name cmdb-backend-prod \
  --resource-group rg-cmdb-gui-prod \
  --slot staging \
  --target-slot production
```
