In April 2023, Node.js released its latest major version with Node.js 20. This major version release, which has been code-named Iron, recently become a Long Term Support (LTS) release in October 2023.
Recently Red Hat released a fully supported Node 20 container image. Every Red Hat build of Node.js release is tested and supported on supported Red Hat OpenShift, Red Hat Enterprise Linux and are based on Universal Base Image.
Red Hat Runtimes are tested and certified against a variety of popular development frameworks and technologies while running on Red Hat OpenShift Container Platform, Red Hat Enterprise Linux. Since we are unable to test every possible framework and version, Red Hat build of Node.js supported components/modules/framework can be found on component details page as per the Module and Framework Support Policies .
You can use the Openshift Client(oc) to create a new application like so:
oc new-app registry.access.redhat.com/ubi8/nodejs-20:latest~https://github.com/nodeshift-starters/nodejs-rest-http
oc expose svc/nodejs-rest-http
Alternatively, you can use the Nodeshift module to deploy a Node.js application from a local directory:
npx nodeshift --dockerImage=registry.access.redhat.com/ubi8/nodejs-20 --expose
