Where can I find the config.yaml?
The config.yaml is created in your storage location when you did theStorage Node step.
For example, if your --mount option in your docker run command looks like --mount type=bind,source=/mnt/storj/storagenode,destination=/app/config, then the config.yaml will be in the /mnt/storj/storagenode location.
Options and parameters specified in the docker run command have a precedence over options in the config.yaml - Only options not also specified in the docker run command will be taken from the config.yamlfile.
