Note: RHSI is not supported for standalone use as a messaging router.
RHSI Operator
The operator is supported with OpenShift 4.x only.
OpenShift versions
- OpenShift 3.11
- OpenShift 4.10, 4.11 and 4.12
- ROSA and ARO

Installing RHSI in a disconnected network by mirroring the required components to the cluster is supported.

- OpenShift Routes
CPU architecture
- x86-64
Podman sites:
Podman-based sites are a Technical Preview feature.
You can create Podman sites only on OS versions where the Skupper CLI and router are supported.
Kubernetes distributions
Red Hat provides assistance running Red Hat Service Interconnect on any CNCF-certified distribution of Kubernetes.
Note, however, that Red Hat Service Interconnect is tested only on OpenShift.
Ingress types
- Contour
- Nginx - This requires configuration for TLS passthrough
- NodePort
Upgrades
Red Hat supports upgrades from one downstream minor version to the next, with no jumps. While Red Hat aims to have compatibility across minor versions, we recommend upgrading all sites to latest version.
If you have applications that require long lived connections, for example Kafka clients, consider using a load balancer as ingress instead of a proxy ingress such as OpenShift route. If you use an OpenShift route as ingress, expect interruptions whenever routes are configured.
For information about the latest release, see Red Hat Service Interconnect Supported Configurations.
