# Cozystack v1.0.0-alpha.1 — "Package-Based Architecture"
|
||||
|
||||
This alpha release introduces a fundamental architectural shift from HelmRelease bundles to Package-based deployment managed by the cozystack-operator. It includes significant API changes that rename the core CRD, Flux sharding for improved tenant workload distribution, enhanced monitoring capabilities, and various improvements to virtual machines, tenants, and the build workflow.
|
||||
|
||||
> **⚠️ Alpha Release Warning**: This is a pre-release version intended for testing and early adoption. Breaking changes may occur before the stable v1.0.0 release.
|
||||
|
||||
## Breaking Changes
|
||||
|
||||
### API Rename: CozystackResourceDefinition → ApplicationDefinition
|
||||
|
||||
The `CozystackResourceDefinition` CRD has been renamed to `ApplicationDefinition` for better clarity and consistency. This change affects:
|
||||
- All Go types and controller files
|
||||
- CRD Helm chart renamed from `cozystack-resource-definition-crd` to `application-definition-crd`
|
||||
- All cozyrds YAML manifests updated to use `kind: ApplicationDefinition`
|
||||
|
||||
A migration (v24) is included to handle the transition automatically.
|
||||
|
||||
### Package-Based Deployment
|
||||
|
||||
The platform now uses Package resources managed by cozystack-operator instead of HelmRelease bundles. Key changes:
|
||||
- Restructured values.yaml with full configuration support (networking, publishing, authentication, scheduling, branding, resources)
|
||||
- Added values-isp-full.yaml and values-isp-hosted.yaml for bundle variants
|
||||
- Package resources replace old HelmRelease templates
|
||||
- PackageSources moved from sources/ to templates/sources/
|
||||
- Migration script `hack/migrate-to-version-1.0.sh` provided for converting ConfigMaps to Package resources

## Major Features and Improvements
|
||||
|
||||
### Platform Architecture
|
||||
|
||||
* **[platform] Migrate from HelmRelease bundles to Package-based deployment**: Replaced HelmRelease bundle system with Package resources managed by cozystack-operator. Includes restructured values.yaml with full configuration support and migration tooling ([**@kvaps**](https://github.com/kvaps) in #1816).
|
||||
* **refactor(api): rename CozystackResourceDefinition to ApplicationDefinition**: Renamed CRD and all related types for better clarity and consistency. Updated all Go types, controllers, and 25+ YAML manifests ([**@kvaps**](https://github.com/kvaps) in #1864).
|
||||
* **feat(flux): implement flux sharding for tenant HelmReleases**: Added Flux sharding support to distribute tenant HelmRelease reconciliation across multiple controllers, improving scalability in multi-tenant environments ([**@kvaps**](https://github.com/kvaps) in #1816).
|
||||
* **refactor(installer): migrate installer to cozystack-operator**: Moved installer functionality to cozystack-operator for unified management ([**@kvaps**](https://github.com/kvaps) in #1816).
|
||||
* **feat(api): add chartRef to ApplicationDefinition**: Added chartRef field to support ExternalArtifact references for flexible chart sourcing ([**@kvaps**](https://github.com/kvaps) in #1816).
|
||||
* **feat(api): show only hash in version column for applications and modules**: Simplified version display in API responses for cleaner output ([**@kvaps**](https://github.com/kvaps) in #1816).
|
||||
|
||||
### Virtual Machines
|
||||
|
||||
* **[vm] Always expose VMs with a service**: Virtual machines are now always exposed with at least a ClusterIP service, ensuring they have in-cluster DNS names and can be accessed from other pods even without public IP addresses ([**@lllamnyp**](https://github.com/lllamnyp) in #1738, #1751).
|
||||
|
||||
### Monitoring
|
||||
|
||||
* **[monitoring] Add SLACK_SEVERITY_FILTER field and VMAgent for tenant monitoring**: Introduced the SLACK_SEVERITY_FILTER environment variable in the Alerta deployment to enable filtering of alert severities for Slack notifications based on the disabledSeverity configuration. Additionally, added a VMAgent resource template for scraping metrics within tenant namespaces, improving monitoring granularity and control ([**@IvanHunters**](https://github.com/IvanHunters) in #1712).
|
||||
|
||||
### Tenants
|
||||
|
||||
* **[tenant] Allow egress to parent ingress pods**: Updated tenant network policies to allow egress traffic to parent cluster ingress pods, enabling proper communication patterns between tenant namespaces and parent cluster ingress controllers ([**@lexfrei**](https://github.com/lexfrei) in #1765, #1776).
|
||||
* **[tenant] Run cleanup job from system namespace**: Moved tenant cleanup job to run from system namespace, improving security and resource isolation for tenant cleanup operations ([**@lllamnyp**](https://github.com/lllamnyp) in #1774, #1777).
|
||||
|
||||
### System
|
||||
|
||||
* **[system] Add resource requests and limits to etcd-defrag**: Added resource requests and limits to etcd-defrag job to ensure proper resource allocation and prevent resource contention during etcd maintenance operations ([**@matthieu-robin**](https://github.com/matthieu-robin) in #1785, #1786).
|
||||
|
||||
### Development and Build
|
||||
|
||||
* **feat(cozypkg): add cross-platform build targets with version injection**: Added cross-platform build targets (linux/amd64, linux/arm64, darwin/amd64, darwin/arm64) for cozypkg/cozyhr tool with automatic version injection from git tags ([**@kvaps**](https://github.com/kvaps) in #1862).
|
||||
* **refactor: move scripts to hack directory**: Reorganized scripts to standard hack/ location following Kubernetes project conventions ([**@kvaps**](https://github.com/kvaps) in #1863).
|
||||
|
||||
## Fixes
|
||||
|
||||
* **fix(talos): skip rebuilding assets if files already exist**: Improved Talos package build process to avoid redundant asset rebuilds when files are already present, reducing build time ([**@kvaps**](https://github.com/kvaps)).
|
||||
* **[kubevirt-operator] Fix typo in VMNotRunningFor10Minutes alert**: Fixed typo in VM alert name, ensuring proper alert triggering and monitoring for virtual machines that are not running for extended periods ([**@lexfrei**](https://github.com/lexfrei) in #1770, #1775).
|
||||

||||
* **[website] docs(storage): simplify NFS driver setup instructions**: Simplified NFS driver setup documentation with clearer instructions ([**@kvaps**](https://github.com/kvaps) in [cozystack/website#399](https://github.com/cozystack/website/pull/399)).
|
||||
* **[website] Add Hidora organization support details**: Added Hidora to the support page with organization details ([**@matthieu-robin**](https://github.com/matthieu-robin) in [cozystack/website#397](https://github.com/cozystack/website/pull/397)).
