alpine:edge-based dockerization of UPX - the "Ultimate Packer for eXecutables"
As the site says:
UPX is an advanced executable file compressor. UPX will typically reduce the file size of programs and DLLs by around 50%-70%, thus reducing disk space, network load times, download times and other distribution and storage costs.
The source code for this image is hosted on GitHub in the backplane/conex repo.
At the moment, this container is simply an Alpine Linux container with the latest release of the UPX binary installed in the /bin directory
