Chapter 1. Before You Begin
1.1. Release Notes
See the Release Notes for important information about this release.
1.2. Version Compatibility and Support
See the Red Hat JBoss Fuse Supported Configurations page for details of version compatibility and support.
1.3. Support for Windows O/S
The developer tooling (oc client and Container Development Kit) for Fuse on OpenShift is fully supported on the Windows O/S. The examples shown in Linux command-line syntax can also work on the Windows O/S, provided they are modified appropriately to obey Windows command-line syntax.
1.4. Comparison: Fuse Standalone and Fuse on OpenShift
There are several major functionality differences:
- An application deployment with Fuse on OpenShift consists of an application and all required runtime components packaged inside a Docker image. Applications are not deployed to a runtime as with Fuse Standalone, the application image itself is a complete runtime environment deployed and managed through OpenShift.
- Patching in an OpenShift environment is different from Fuse Standalone, as each application image is a complete runtime environment. To apply a patch, the application image is rebuilt and redeployed within OpenShift. Core OpenShift management capabilities allow for rolling upgrades and side-by-side deployment to maintain availability of your application during upgrade.
- Provisioning and clustering capabilities provided by Fabric in Fuse have been replaced with equivalent functionality in Kubernetes and OpenShift. There is no need to create or configure individual child containers as OpenShift automatically does this for you as part of deploying and scaling your application.
- Fabric endpoints are not used within an OpenShift environment. Kubernetes services must be used instead.
- Messaging services are created and managed using the A-MQ for OpenShift image and not included directly within a Karaf container. Fuse on OpenShift provides an enhanced version of the camel-amq component to allow for seamless connectivity to messaging services in OpenShift through Kubernetes.
- Live updates to running Karaf instances using the Karaf shell is strongly discouraged as updates will not be preserved if an application container is restarted or scaled up. This is a fundamental tenet of immutable architecture and essential to achieving scalability and flexibility within OpenShift.
- Maven dependencies directly linked to Red Hat Fuse components are supported by Red Hat. Third-party Maven dependencies introduced by users are not supported.
- The SSH Agent is not included in the Apache Karaf micro-container, so you cannot connect to it using the bin/client console client.
- Protocol compatibility and Camel components within a Fuse on OpenShift application: non-HTTP based communications must use TLS and SNI to be routable from outside OpenShift into a Fuse service (Camel consumer endpoint).
