[docker-compose] ERROR: for postgresd expected string or buffer

[VRspace4]

Hi, I'm getting the following error when executing the command docker-compose up --build from the latest git clone on a CentOS 7 machine. I tried switching from postgres to mysql and had similar "expected string or buffer" error. Please advise.

[root@rm hydra]# docker-compose up --build

Looks like a docker compose issue, either retry, reinstall docker, or ask in docker github :)
