Jeff Smith 2021-05-09 : Below is an online demo using CloudTk. This demo runs "frogger" in an Alpine Linux Docker Container. It is a 27.4MB image which is made up of Alpine Linux + tclkit + frogger.kit + libx11 + libxft + fontconfig + ttf-linux-libertine. It is run under a user account in the Container. The Container is restrictive with permissions for "Other" removed for "execute" and "read" for certain directories.
