Next-generation OpenStack dashboard — Horizon’s feature completeness + Skyline’s modern UX

Afterglow is an open-source web dashboard for OpenStack cloud environments. It preserves Horizon’s stability and feature coverage while adopting Skyline’s modern UI/UX. It also ships a k3s-based Kubernetes provisioning stack that replaces Magnum.

Highlights

k3s Cluster Provisioning

Installs k3s directly onto OpenStack VMs to deliver a Kubernetes environment on demand. No complex Magnum setup — master and worker nodes are configured automatically through cloud-init.

OverlayFS Library Layer

Mounts Manila NFS/CephFS shares as OverlayFS lower layers so that AI/ML libraries (Python, PyTorch, vLLM) can be shared across many VMs. Storage efficiency and boot speed improve at the same time.

Monitoring Integration

Issues Grafana embed JWTs (POST /api/grafana/token) and exposes VM targets for Prometheus via http_sd (GET /api/sd/prometheus/targets). Monitoring ingress security groups are attached automatically on project and instance creation.

kolla-ansible Integration

Deploys Afterglow inside an existing OpenStack cluster using a single kolla-ansible playbook (deploy/kolla/).

Complete OpenStack Service Coverage

Nova, Glance, Cinder, Neutron, Manila, Octavia — every core service managed from a single dashboard.
