Just curious if anyone else encountered this same error from the initial "docker run" command:
docker: Error response from daemon: create ./pg-data: "./pg-data" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intended to pass a host directory, use absolute path.
