Native ingress does not support log deletion endpoints in Loki Helm Chart

[ojroques]

Describe the bug
Native ingress does not support log deletion endpoints in Loki Helm Chart. This is because the endpoints are not defined in the values.yaml: https://github.com/grafana/loki/blob/main/production/helm/loki/values.yaml#L1175-L1215.

To Reproduce
Steps to reproduce the behavior:

1. Use Loki Helm Chart in any mode
2. Use the native Ingress instead of the gateway:

ingress:
  enabled: true

3. Query the log deletion endpoint/loki/api/v1/delete:

curl \
  --request "POST" \
  --get \
  --data-urlencode "start=$(date -d '1 hour ago' '+%s')" \
  "https://<hostname>/loki/api/v1/delete"

We get 404 page not found.

Expected behavior
The log deletion endoints are defined.

Environment:

• Infrastructure: Kubernetes
• Deployment tool: Helm
