Description of problem:

There has been a customer request to upgrade to Node 18 in the downstream UDI: https://issues.redhat.com/browse/CRW-4532

There is an official UBI8/NodeJS-18 image which we could base our Node 18 installation off of: https://catalog.redhat.com/software/containers/ubi8/nodejs-18/6278e5c078709f5277f26998

Workaround:

The downstream UDI can be extended via another Dockerfile to install Node 18 on it:

FROM registry.redhat.io/devspaces/udi-rhel8:3.7-18.1692027007
ENV NODEJS_VERSION="18"
RUN dnf -y -q module reset nodejs && \
    dnf -y -q module install nodejs:$NODEJS_VERSION && \
    dnf -y -q install --setopt=tsflags=nodocs \
        nodejs
