3.3. New features in Fuse 7.2
The main new features of Fuse on OpenShift in version 7.2 are:
- Define APIs using the Apicurito API designer
- Fuse 7.2 on OpenShift now ships with a lightweight version of the Apicurio Studio API designer, enabling you to create API definitions in OpenAPI (Swagger) format.
- New API project generator with Apicurito generator
- Apicurito provides the option to generate starting point code for an API implementation, based on a given API definition. The starting point code includes a skeleton implementation of the specified API and all of the configuration necessary to build and deploy the Fuse application to OpenShift.
- Integration with 3scale service discovery
- A project generated by Apicurito also includes the metadata required to enable service discovery in the Red Hat 3scale API Management administrative console.
- Updated Fuse Console (Hawtio) on OpenShift
The Fuse Console on OpenShift has been updated with the following features. The Fuse Console:
- Has an app launcher widget in the navigation bar, to ease switching between consoles.
- Has a context switcher widget in the navigation bar of the JVM console, to ease switching between containers.
- Groups pods by deployment or deployment configuration in the list view.
- Displays Camel route counts in the Pods view.
- Displays the user ID and username in the navigation bar menu.
- OpenShift resources are displayed with clickable links that open the corresponding resources in the OpenShift Web console.
- Prometheus fully supported on OCP 3.11
- Prometheus is out of technology preview and is now fully supported for Fuse 7.2 on OpenShift Container Platform (OCP) 3.11.
3.4. Important notes
Important notes for the Fuse 7.2 release of the Fuse on OpenShift distribution:
- Fuse on OpenShift images are now distributed through a secure registry
-
From Fuse 7.2.0, Fuse on OpenShift images are distributed through the secure Red Hat registry,
registry.redhat.io. In order to install the images for Fuse 7.2 on OpenShift, you need to configure your credentials in OCP to gain access to the secure registry. For instructions on how to configure the credentials, see Get Started for Administrators in the "Fuse on OpenShift Guide" guide. - Builds can get stuck on some early micro versions of OCP 3.10
- If you are using Fuse on OpenShift with OCP 3.10, we recommend that you install OCP 3.10.34 or later to avoid encountering this known issue, ENTESB-9420. For this reason, it is also recommended that you do not use Fuse 7.2 with Red Hat Container Development Kit (CDK) 3.5, which is based on an affected OCP 3.10 version. Use CDK 3.8 instead.
- Redeploying an application using the Fabric8 Maven plugin
When deploying a Fuse on OpenShift application to OpenShift Container Platform using the Fabric8 Maven plugin, you cannot redeploy the application using just the command
mvn fabric8:deploy. Use the following sequence of commands instead:mvn fabric8:undeploy mvn fabric8:deploy
mvn fabric8:undeploy mvn fabric8:deployCopy to Clipboard Copied! Toggle word wrap Toggle overflow
