OCM/ACM Compatibility
Krkn Operator supports multi-cluster chaos testing on Kubernetes and OpenShift. Cluster discovery can be manual or automated through ACM/OCM integration.
INFO
Multi-cluster works without ACM/OCM. Clusters registered manually through the web console have the exact same capabilities as clusters discovered via ACM. The integration is optional — it adds automatic discovery, not functionality.
Platform Support
| Platform | Status |
|---|---|
| Kubernetes 1.19+ | Supported |
| OpenShift 4.x | Supported |
ACM Compatibility
The following versions of Red Hat Advanced Cluster Management have been tested and validated with Krkn Operator:
| ACM Version | Status |
|---|---|
| 2.14 | Tested |
| 2.15 | Tested |
| 2.16 | Tested |
OCM Compatibility
The following versions of Open Cluster Management have been tested and validated:
| OCM Version | Status |
|---|---|
| 1.1.0 | Tested |
| 1.2.0 | Tested |
| 1.3.1 | Tested |
INFO
Older ACM versions may work but are not actively tested. We recommend running one of the validated versions above.
How ACM Integration Works
When ACM is enabled (--set acm.enabled=true at install time), Krkn Operator deploys a dedicated component that connects to the ACM hub and automatically discovers managed clusters. Discovered clusters appear in the same cluster pool as manually registered targets — users select from both without distinction.
See Provider Configuration for setup details and Installation for the Helm flag.
