docker-entrypoint.sh:

VAR_DEF_VERSION="11.0.3"

VAR_DEF_ZIP_DOWNLOAD_URL="http://ci.una.io/builds/UNA-v.${UNA_VERSION:-$VAR_DEF_VERSION}.zip"

VAR_DEF_ZIP_FOLDER="UNA-v.${UNA_VERSION:-$VAR_DEF_VERSION}"

There is a bootleg Docker Compose yml available on my Github (https://github.com/rnwilson/una-camp) it would have taken a lot longer without the Official image and I left out some of the functionality the Official offers. It by far is a better solution that what I made available but you don't have to be an experienced DevOps professional to figure out if you'd like another version installed one would change the VAR_DEF_VERSION variable.
