Log files, if not moved, are created by default in these locations:
Linux/Docker :
# Path to log files:
docker ps -a #get instance-id, the beggining of container-id
ls -l #get dirs and files details
# Ubuntu:
sudo su
cd /var/lib/docker/containers/
cd <containerID>
# full path - assuming use json-file as log driver:
/var/lib/docker/containers/<containerID>/<containerID>-json.log
# Synology:
sudo su
cd /volume1/@docker/containers/
cd <containerID>
# full path - assuming use json-file as log driver and Docker installs on volume1:
/volume1/@docker/containers/<containerID>/<containerID>-json.log
Windows - as service:
C:/Program Files/Storj/Storage Node/storagenode.log
