I’m sure a lot of us would have faced this issue of storage getting filled without doing anything. This might be majorily because our docker logs would have consumed it fully.
I was wondered to see that a log file was consuming 10GB of HDD storage.
In order to get back the storage we need to truncate the files. First find which are the large files.
du -d1 -h /var/lib/docker/containers | sort -h
And then truncate the files with following command.
cat /dev/null > /var/lib/docker/containers/container_id/container_log_name
