$ docker pull st0012/goby:latest
# In container, default working directory is /go/src/github.com/goby-lang/goby
$ docker run -t -v PATH_TO_TARGET_FILE_DIR:/go/src/github.com/goby-lang/goby st0012/goby:latest goby TARGET_FILE
For example if I want to run ./samples/loop.gb, I will run
$ docker run -t -v `pwd`/samples:/go/src/github.com/goby-lang/goby st0012/goby:latest goby loop.gb
