Unikorn Releases

Unikorn is a relatively large collection of independent microservices that combine to provide IaaS/PaaS functionality. Maintaining a matrix of compatible versions is complex due to a lot of inter-dependencies. This repository aims to simplify the task by bundling together versions that are know to work together and notify of any breaking changes before the project becomes GA.

Releases

v0.1.2

28 November 2024

Component	Version
Core	v0.1.86 🆕
Identity	v0.2.46 🆕
Region	v0.1.46 🆕
Kubernetes	v0.2.53 🆕
UI	v0.2.41 🆕

Relase Notes

• Makes networks generic to lay a foundation for the compute service.
• Adds in server provisioning to the region controller.
• Streamlines region resource deletion.
• Adds Kubernetes control plane node selection resource limits.
• RBAC has been tigtened significantly.

Upgrade Instructions

• PhysicalNetwork resources are now Network resources, so all infrastructure in regions with physical network suport will need to be torn down and rebuilt. Further to that, the APIs have been modified in the same way.
• HelmApplications now make use of the new generic tags type, so you must delete all existing applications first in order to perform a clean upgrade: kubectl delete helmapplications -A --all.

Breaking Changes

• Any clients that relied on metadata tags on resources will need to be modified to read this from the generic metadata header, and not the spec.
• Images and flavors should be read from the relevant service from now on as those can provide context specific filtering.

v0.1.1

5 November 2024

Component	Version
Core	v0.1.79
Identity	v0.2.44 🆕
Region	v0.1.45 🆕
Kubernetes	v0.2.46 🆕
UI	v0.2.39 🆕

Release Notes

• Improves RBAC so users who use one service no longer need direct access to requisite services.
• Remove flavor/image filtering from the region service, these need to be proxied through the top level service e.g. kubernetes, as those contain the domain specific knowledge to filter correctly.

Breaking Changes

• 3rd party UX components will be affected by a number of API changes:
  • Any ACL reliant code needs to be aware endpoints have changed e.g. projects becomes identity:projects.
    • In general the form is <service>:<resource> meaning we can do things like region:* in the future as a terse way of granting access to everything.
    • A full list of officially supported endpoints is available here.
  • Users can no longer access flavors and images directly through the region service.
    • This is a fairly trivial thing to fix as the APIs remain the same, they now belong to the service that consumes those resources.
    • This allows the Kubernetes service for example to filter out flavors that kubeadm cannot use, independently of the compute service.
