## TL;DR
|
|
|
|
<details>
|
|
<summary>Setup</summary>
|
|
|
|
Requires:
|
|
|
|
- A [Prometheus] instance to be available.
|
|
|
|
> [!caution]
|
|
> OpenCost's pods **will** error out and go in CrashLoopBackoff if it cannot connect to Prometheus.<br/>
|
|
> See the Helm chart values at `opencost.prometheus` to configure that connection.
|
|
|
|
- The above Prometheus instance to have a scrape target configured for OpenCost.<br/>
|
|
See [OpenCost extraScrapeConfigs for Prometheus].
