prometheus_gpu_metrics_chart_version

Description

The prometheus_gpu_metrics_chart_version parameter pins the Helm chart version for the free-plan Prometheus chart deployed via the Convox Console (prometheus-community/prometheus). Applies on next Disable→Enable cycle from the Convox Console. Change this value to roll forward to a CVE hotfix release without waiting for a Convox rack version that bumps the default.

The chart is prometheus-community/prometheus from the upstream https://prometheus-community.github.io/helm-charts repo. The release is named prometheus-gpu-metrics and lives in the kube-system namespace.

Default Value

The default value is the chart version that ships with this rack release — currently 27.9.0.

Use Cases

CVE response: When the upstream chart publishes a security fix patch (e.g., 27.9.0 → 27.9.1), pin to the patched version immediately rather than waiting for the next Convox rack release.
Rollback after an issue: If a chart patch introduces an issue on your workload, pin back to the prior known-good version while you investigate.

Setting Parameters

To pin to a specific chart version:

$ convox rack params set prometheus_gpu_metrics_chart_version=27.9.1 -r rackName
Setting parameters... OK

To revert to the rack default:

$ convox rack params set prometheus_gpu_metrics_chart_version=27.9.0 -r rackName
Setting parameters... OK

You must enable monitoring (free plan) in the Convox Console for the free-plan Prometheus chart to be deployed at all — pinning the version is otherwise a no-op until you enable monitoring. The new chart version takes effect on the next Disable→Enable cycle from the Console.

Additional Information

Stay on the same chart major version (e.g., within 27.x) when pinning. Chart majors may introduce subchart name changes or values-schema breakage that the Convox provider does not yet handle.
The chart audited for 27.9.0 (the default at this rack release) installs zero CRDs and zero admission webhooks, so helm uninstall cleanly removes all resources. A future chart major requires a re-audit and possibly a Convox rack release before adoption is safe.
Always verify the chart you pin to is published at the prometheus-community upstream Helm repo: https://prometheus-community.github.io/helm-charts. Convox does not vendor the chart.

gpu_observability_enable: Enables the DCGM exporter on this rack. The Console-deployed Prometheus chart scrapes DCGM when monitoring is enabled in the Console.
prometheus_gpu_metrics_retention: Retention window for the free-plan Prometheus chart deployed via the Convox Console.

Version Requirements

This parameter requires at least Convox rack version 3.24.6.
