Neo4j.conf file is missing when creating a cluster

I have created a neo4j cluster using YAML file, when run the file using docker-compose up --detach everything runs fine but the neo4j.conf file is missing.

version: "3"

This line right here says that you will provide the conf file by writing one and placing it in your local reap-cluster/core1/conf directory. Since that directory appears to be empty, neo4j probably can't start because you haven't configured it. :slight_smile:

The solution is to either write your own config file and place it in that directory, or else don't mount the /conf volume in the docker container and let Neo4j generate its own default config.
