🔧 Configuration

Customize Exchange Rate

To use a different exchange rate or currency, modify the API endpoint:

$response = Invoke-RestMethod -Uri "https://open.er-api.com/v6/latest/USD" $usdToInr = [math]::Round($response.rates.INR, 2)

Replace INR with your desired currency code (e.g., EUR, GBP, JPY).

Adjust Cost Estimates

Cost calculations are based on standard GCP pricing. Update these variables in the script:

$computeCostPerNode = 24.50 # e2-medium cost $diskCostPerGB = 0.040 # Standard persistent disk $lbMonthlyCost = 18.00 # Per forwarding rule
