The primary reason that the image is so large is that it contains all the data needed for scanning. IMHO, this is a good thing. Otherwise, it would take significantly longer to spin up a new container as all the data needed for scanning would have to be downloaded. Personally, I prefer for the image to contain the scanning data and be as up to date as possible so that I can launch a container and update definitions in a reasonable amount of time.

Fyi this still uses openvas 9 while 11 is available.

It might be possible to reduce the image size by using a smaller base image than Ubuntu.
