I am trying to install extensions on demand, starting from the light docker image with the follwoing Dockerfile
# The development environment
FROM lucee/lucee:6.2.4.24-light-nginx-tomcat11.0-jre21-temurin-noble AS dev
# Start Tomcat, to install extensions and exit
ARG LUCEE_LOGGING_FORCE_APPENDER=console
ARG LUCEE_ENABLE_WARMUP=true
ARG LUCEE_ADMIN="CED6227E-0F49-6367-A68D21AACA6B07E8;name=Lucee Administrator;label=1.0.0.6"
ARG MS_SQL="99A4EF8D-F2FD-40C8-8FB8C2E67A4EEEB6;name=Microsoft SQL Server (Vendor Microsoft);label=12.6.3.jre11"
ARG LUCEE_EXTENSIONS="${LUCEE_ADMIN},${MS_SQL}"
RUN /usr/local/tomcat/bin/catalina.sh run
# Environment variables embedded into the image
ENV LUCEE_EXTENSIONS="${LUCEE_EXTENSIONS}"
ENV LUCEE_LOGGING_FORCE_APPENDER=console
ENV LUCEE_ADMIN_ENABLED=true
ENV LUCEE_ADMIN_PASSWORD=password
# Engage
CMD ["/usr/local/tomcat/bin/catalina.sh", "run"]
It appears during container build Lucee dows not resolve the correct version of the MS SQL Server driver:

Since I exported LUCEE_EXTENSIONS to the environment as well, during container startup it checks the version of the extension and finds:

In the Lucee Administrator it tells me I currently have version 6.2.1-jre8 installed. Upgrade gives the error Given version [6.2.1-jre8] is invalid, a valid version is following this pattern ..[.], uninstall and then install works.
