How to reconcile Kubernetes and cloud billing with your AI

Connect OpenCost to your AI client to bridge the gap between cluster resource usage and your cloud provider's bill.

Ask AI about this page

Short answer

How can I match my K8s usage to my cloud bill?

Your AI pulls resource allocation data from OpenCost and compares it to the actual costs reported by your cloud provider. This identifies where your cluster usage and invoices diverge. You'll see exactly where the money is going.

The outcomes.

Where the data lands.

The AI processes the raw numbers into these specific outcomes.

ANALYSIS

Discrepancy reports

The AI compares cluster metrics against provider invoices. You get a clear view of any missing or unexpected costs.

USAGE

Resource mapping

The AI maps specific Kubernetes workloads to their actual dollar cost. This shows which pods or namespaces are driving your bill.

AUDIT

Billing verification

The AI validates that your cloud provider is charging you correctly for the resources your cluster actually used.

HUMAN

Manual adjustments

The AI flags anomalies that require you to manually investigate or adjust your cloud provider's billing settings.

The workflow

What your AI does when the data arrives.

The AI handles the heavy lifting of data comparison so you don't have to manually export CSVs.

  1. Fetch cluster usage

    The AI pulls the current resource allocation data from your Kubernetes cluster.

    get_allocation

  2. Fetch cloud costs

    The AI retrieves the actual billing data from your cloud provider to see what you were charged.

    get_cloud_cost

  3. Identify gaps

    The AI compares the two datasets to find mismatches between what the cluster used and what the provider billed.

    get_allocationget_cloud_cost

  4. Summarize findings

    The AI presents the delta between usage and billing in a format you can act on immediately.

    get_cloud_cost

FAQ

How this task behaves.

  • 01

    Can the AI change my cloud billing settings?

    No. The AI can only read usage and cost data. It cannot modify your cloud provider's billing configurations or your Kubernetes settings.

  • 02

    Does the AI delete any cluster data?

    No. The AI only performs read operations to fetch data for comparison. It has no capability to delete or modify your cluster resources.

  • 03

    How does it handle different cloud providers?

    The AI uses the cloud cost tool to pull data from the specific provider you specify in your prompt.

  • 04

    Can I use this to automate my monthly billing reports?

    Yes. You can ask your AI to generate a summary of the differences between usage and billing for any given period.

  • 05

    What happens if the cloud bill and cluster usage don't match?

    The AI will highlight the specific delta and identify which resources or namespaces are causing the mismatch.
