v1.0.0

This is the first stable release of CAPCS. 🎉

See docs/getting-started.md for a quick start guide.

What CAPCS provisions on cloudscale.ch

• Servers for control plane and worker Machines, placed in server groups for anti-affinity.
• Networks — either managed by CAPCS or an existing network you supply.
• Load balancers for the control plane endpoint (public or private), with pool members reconciled as machines come and go.
• Floating IPs as an alternative control plane endpoint, either CAPCS-managed or pre-existing.
• Dual-stack (IPv4 + IPv6) where the flavor supports it.

Cluster API features supported

In addition to the standard features required, CAPCS supports:

• ClusterClass / topology: the shipped quick-start ClusterClass (templates/cluster-class.yaml) plus the topology flavor. See getting-started → topology flavor.
• Scale-from-zero: CloudscaleMachineTemplate publishes status.capacity (cpu, memory) so the cluster autoscaler can size MachineDeployments from zero replicas.
• Per-cluster credentials via CloudscaleCluster.spec.credentialsRef.

Cluster templates

Five flavors ship as release assets, covering managed and pre-existing networks, public LB and floating-IP endpoints, and private-only nodes behind a NAT gateway. Matrix: getting-started → flavors.

Operations

• Webhooks own all defaulting and validation, including immutability of region/zone/network config.
• Observability: controller-runtime metrics on :8443, opt-in OpenTelemetry tracing and pprof. Details: docs/observability.md.
• Tested against Kubernetes v1.34.x-v1.36.x.

What's Changed since v0.1.0-beta.3

v1.0.0-rc.1

What's Changed

• chore: prep stable release by @mweibel in #43

Full Changelog: v0.1.0-beta.3...v1.0.0-rc.1

v0.1.0-beta.3

What's Changed

• Kubebuilder upgrade v4.14.0 by @mweibel in #37
• fix AI-quality findings: BeZero endpoint, FloatingIP test coverage, sed/cancel cleanup by @mweibel in #38
• Improve documentation by @mweibel in #33

• feat: Observability by @mweibel in #36

Full Changelog: v0.1.0-beta.2...v0.1.0-beta.3

v0.1.0-beta.2

What's Changed

• Configuration for the number of concurrent cluster and machine reconciliations is now possible via controller flags.
• ClusterClass support
• Overall controller resiliency has been improved, ensuring that edge cases do not result in logic failure. This includes timeout handling for all reconciles and API calls.
• A bug concerning node upgrades and LoadBalancer has been resolved (reported by @mdnix - thanks!).
• The build now utilizes Go 1.26, along with upgraded dependencies.

⚠️ Breaking Changes

As part of this beta release, the following minor changes have been implemented in CRDs:

• Removal of CloudscaleCluster.spec.controlPlaneLoadBalancer.ipFamily: This field has been removed because the LoadBalancer’s IP Family is determined dynamically by the network it is provisioned into.
• Tightened Validation for ipFamily: Input validation has been restricted, ensuring that only semantically appropriate values are permitted in certain contexts.

⚠️ Action Required: The CRDs must be re-applied to the cluster if an existing management cluster is running.

Changelog

• Improve resiliency by @mweibel in #31
• consolidate test helpers and reduce duplication by @mweibel in #35
• feat: add ClusterClass support by @mweibel in #32
• chore(deps): bump the all-minor-patch group across 1 directory with 11 updates by @dependabot[bot] in #34

Full Changelog: v0.1.0-beta.1...v0.1.0-beta.2

v0.1.0-beta.1

⚠️ This is a pre-release. CAPCS v0.1.0-beta.1 is the first public beta and is not recommended for production use.
APIs and behavior may change before the stable v0.1.0 release.

What's New

This is the first release of the Cluster API InfraProvider for cloudscale.ch (CAPCS).

Features

• Cluster Lifecycle — CloudscaleCluster supports managed networks, pre-existing networks, load balancers, and
  floating IPs.
• Machine Provisioning — CloudscaleMachine provisions cloudscale.ch servers with cloud-init and configurable
  network interfaces.
• Private Networking — Multiple cluster templates for public-LB/private-nodes and floating-IP topologies.
• Autoscaling from Zero — Machine capacity reporting enables cluster-autoscaler scale-from-zero.
• E2E Test Suite — Lifecycle, HA, upgrade, self-hosted, MD-remediation, and Kubernetes conformance tests.
