Chapter 4. Known Issues for CodeReady Workspaces on IBM Z and IBM Power Systems

4.1. IBM Z [Technology Preview]

Support for deploying CodeReady Workspaces on OpenShift Container Platform on IBM Z is currently only available as a Technology Preview feature. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For details about the level of support for Technology Preview features, see Technology Preview Features Support Scope.

4.1.1. Installations in restricted environments are not supported on IBM Z

Advanced features like, for example, restricted environment installation, while possible, are unsupported.

4.1.2. Unsupported devfiles on IBM Z

  • EAP for OpenJDK 8
  • .Net

4.1.3. Debugging cannot be activated in Go workspaces

Debugging feature cannot be activated in Go workspace in CodeReady Workspaces 2.5. An attempt to activate this feature results in the Failed to continue error message.

4.1.4. Deployment of Red Hat Fuse sample project to an OpenShift 4.5 cluster running on IBM Z (s390x) fails
