Unless you set it in the config it wont have any logs on the system only able to run docker commands to get the logs.
Not really sure what you mean by this just the OS installed probably uses 9gigs after updates and installing docker.
If you are running Swap it will use more of the drive space, You can disable swap though.
just for your information, regarding my question about the disk usage: there was a docker container used 10+ GB of storage. I’ve deleted it and restarted everything. disk usage is now around 5 GB instead of almost 15 GB.
@Alexey I’ve also added the memory option. what is it for? the bash output shows, when starting the node:
WARNING: Your kernel does not support memory limit capabilities or the cgroup is not mounted. Limitation discarded.
thank you all! it will take a while, going through all your feedbacks.
