Trying a different approach for building THREDDS

# Run THREDDS until a successful startup to generate initial files

# This means that later we can run with a readonly root filesystem for security purposes

RUN catalina.sh start && \

    # Sleep for 5s to avoid connection refused errors (curl version is too old for --retry-connrefused)

    sleep 60 && \

    # Try to fetch the catalog every 5s for 5m before failing

    curl -fsSL -o /dev/null --retry 60 --retry-delay 5 --retry-max-time 300 http://127.0.0.1:8080/thredds/catalog/catalog.html && \

    catalina.sh stop && \

    # Remove any transient files that were created

    rm -f ./logs/catalina.{log,out} && \
