Namespace, InfluxDB 2.7.12 StatefulSet with PVC and a NetworkPolicy that admits only the server, the server Deployment (non-root, read-only root filesystem), a cert-manager Certificate from letsencrypt-prod and a Traefik IngressRoute. Secrets are a template only. Nothing is applied; k8s/README.md has the steps. Server version bumped to 1.1.0. Validated offline with kustomize and kubeconform (including the cert-manager and Traefik CRD schemas). The InfluxDB container was tested locally as UID 1000 with no capabilities.

# creates the org, the bucket and the admin token from the influxdb-auth Secret; on later
|
|
# starts those variables are ignored and the data on the volume wins.
