Docker image build fails on AWS EC2

[Raydrian]

Hi, I'm currently trying to build the docker image on AWS EC2 and this error keeps popping up:

Error processing tar file(exit status 1): write /usr/local/lib/python3.6/dist-packages/spacy/training/example.cpython-36m-x86_64-linux-gnu.so: no space left on device

Now, I'm using an xlarge EC2 instance with 16GB and Docker info shows that I have 15.36GB. It's therefore unlikely that this is actually a memory issue, does anyone know what's going on?
