docker-compose up -d ends up in errors

Hi,

I tried to set up mailcow:dockerized. I followed the steps in the installation documentation. Always I try docker-compose up -d I get the below errors:

I disabled the firewall but the errors still occur. I set enable_ipv6: false under networks in docker-compose.yml but it does not help. Can anybody help?

I downgraded the docker version to 17.06.2. I started my containers again with docker-compose up -d and everthing works well without problems. It seems that my OpenVZ-Server does not provide every Kernel Feature which the newest Docker-Version needs. Obviously this is a Docker issue. Issue can be closed.
