I need a breakdown of my usage inside a single project categorized on the basis of Pods or Services or Deployments but the billing section in console doesn't seem to provide such granular information. Is it possible to get this data somehow? I want to know what was the network + compute cost on per deployment or pods. Or maybe if it is possible to have it atleast on the cluster level? Is this breakdown available in BigQuery?
Recently it was released a new features in GKE that allows to collect metrics inside a cluster that can also be combined with the exported billing data to separate costs per project/environment, making it possible to separate costs per namespace, deployment, labels, among other criteria.
It's not possible at the moment to breakdown the billing on a pod level, services or deployment, Kubernetes Engine uses Google Compute Engine instances for nodes in the cluster. You are billed for each of those instances according to Compute Engine's pricing, until the nodes are deleted. Compute Engine resources are billed on a per-second basis with a 1 minute minimum usage cost.
You can Export Billing Data to BigQuery enables you to export your daily usage and cost estimates automatically throughout the day to a BigQuery dataset you specify. You can then access your billing data from BigQuery then you can use BigQuery queries on exported billing data to do some breakdown.
You can view your usage reports as well and estimate your kubernetes charges using the GCP Pricing Calculator. If you want to move forward you can create a PIT request as a future request
