Collabora Online Controller 1.1.4
Released on 29 August 2025.
Features
- Remote dynamic configuration via
/controller/remoteconfighttps://sdk.collaboraonline.com/docs/installation/Configuration.html?#remote-dynamic-configuration - Health/readiness split: /healthz and /readyz; only the elected leader becomes Ready.
Bug Fixes/Improvements
- Leader‑only serving; followers remain Healthy but never Ready.
- Lease cleanup on uninstall to prevent orphaned leader‑election locks.
- Runs as unprivileged user by default.
- Monitor Origin mismatch resolved (COOL adds “Origin”; accepted correctly).
- No traffic forwarded to followers.
Action Required
- Pre‑upgrade cleanup to avoid stale leadership: kubectl delete -n collabora leases.coordination.k8s.io collabora-online Expected: lease.coordination.k8s.io “collabora-online” deleted
- Use helm charts: umbrella 1.1.6; controller 1.1.7.
