I'm installing gremlin-server on Plesk using his docker container but I got an error reading default settings:

WARNING: /opt/gremlin-server//opt/gremlin-server/conf/gremlin-server.yaml is unreadable Configuration file not found.

If I run it on my local docker I have no problems.

docker run --rm --name test tinkerpop/gremlin-server

How can I fix the settings on Plesk?
