Prometheus Agent

This chart deploys Prometheus in agent mode to scrape Kubernetes metrics and write them to a central Prometheus endpoint.

Secrets

To securely provide the remote write credentials, create a Kubernetes Secret named prometheus-remote-write-credentials in the target namespace.

REMOTE_WRITE_USERNAME="your-username"
REMOTE_WRITE_PASSWORD="your-secret-password-here"
kubectl create secret generic prometheus-remote-write-credentials \
    --from-literal=username="$REMOTE_WRITE_USERNAME" \
    --from-literal=password="$REMOTE_WRITE_PASSWORD" \
    -n <namespace>
