I met the same error. Have you figured it out? How did you solve the problem?

I met the issue, and it is related docker permission. You just need to add your username to docker, such that you don't need to do sudo docker etc. to execute

For those having the same issue, this is because the code tries to launch multiple containers which all communicate via 127.0.0.1. This might not work if you don't have access to root or if you are working on a server with namespaces. I have forked this repo and solved this issue by using a Docker Compose to create a pseudo-network for the containers to communicate on. Feel free to use it.
