Actually, the issue now was with using the pantsbuild/centos6 docker image from your docker hub. I can’t seem to get docker and docker-compose to work on the image. My latest error is this bad boy:

docker-compose: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /tmp/_MEIPxHDvM/libz.so.1)
