Stackube Release Note
1.0 Beta
Prelude
This is the 1.0 Beta release of Stackube: a secure, multi-tenant and Kubernetes centric OpenStack distribution.
| New Features |
|---|
| 1. Implemented a auth controller watches on tenant/networks/namespaces |
| change and setups RBAC roles for tenant. This is how we match Kubernetes |
| authorization control with OpenStack tenant by: tenant namespace 1:1 |
mapping. Controller is implemented by using CRD of Kubernetes. |
| 2. Implemented a network controller watches on networks/namespaces change |
| and operates OpenStack network based on network namespace 1:1 mapping. This |
| is how to define Kubernetes multi-tenant network by using Neutron. |
Controller is implemented by using CRD of Kubernetes. |
| 3. Implemented a CNI plug-in which name is kubestack. This is a CNI plug-in |
| for Neutron and work with the network controller model mentioned above. When |
| network of Neutron is ready, kubestack will be responsible to configure Pods |
to use this network by following standard CNI workflow. |
| 4. Implemented stackube-proxy to replace default kube-proxy in Kubernetes so |
that proxy will be aware of multi-tenant network. |
| 5. Implemented stackube DNS add-on to replace default kube-dns in Kubernetes |
so that DNS server will be aware of multi-tenant network. |
| 6. Integrated cinder-flexvolume of kubernetes/frakti project so that hypervisor based container runtime (runV) in Stackube can mount Cinder volume (RBD) directly to VM-based Pod. This will bring better performance to |
user. |
| 7. Improved stackube-proxy so that Neutron LBaaS based service can be used |
in Stackube when LoadBalancer type service is created in Kubernetes. |
| 8. Created Docker images for all add-on and plug-in above so they can be |
deployed in Stackube by one command. |
| 9. Add deployment documentation for Stackube which will install Kubernetes + |
mixed container runtime + CNI + volume plugin + standalone OpenStack components. |
