I’m trying to get a docker image built for Scry. I need the image to run specs on travis and also so I can build a linux distribution.
Here’s the output when I try to run crystal spec
% docker run kofno/scry /bin/sh -c "cd /opt/scry; crystal spec" ✹ ✭

If you have any llvm or docker chops, your help would be appreciated. Here’s the link to the dockerfile → https://github.com/kofno/scry/blob/master/Dockerfile
