General Summary

I am experiencing an issue where I am unable to set specific environment variables necessary for Prometheus integration within the MinIO management panel despite following the configuration guidelines.

Expected Behavior

I expect to set MINIO_PROMETHEUS_URL and MINIO_PROMETHEUS_JOB_ID environment variables to display Prometheus metrics on the MinIO control panel.

Current Behavior

Despite setting the environment variables in a Kubernetes Secret and through Helm chart values as described in the documentation, they are not being recognized or applied within the MinIO deployment. When checking the environment variables using kubectl exec and viewing the /tmp/minio/config.env, the specified variables are not present or contain incorrect values.

Possible Solution

Not obligatory, but suggest a fix/reason for the bug, or ideas how to implement the addition or change.

Steps to Reproduce (for bugs)

1. Set up the Kubernetes Secret with the following values:

   apiVersion: v1
   kind: Secret
   type: Opaque
   metadata:
     name: minio-config-secret
   stringData:
     config.env: |
       export MINIO_PROMETHEUS_URL='http://prometheus-kube-prometheus-prometheus.prometheus.svc.cluster.local:9090'
       export MINIO_PROMETHEUS_JOB_ID="minio-job"
   

2. Deploy MinIO using Helm with the following value set for existingSecret: true.
3. Check the environment variables using kubectl exec <pod-name> -- env
4. Check the file /tmp/minio/config.env.

Context

I am trying to integrate Prometheus with MinIO to monitor performance metrics directly from the MinIO console but am unable to do so due to this issue.

Regression

No
