Docker Root Dir: /var/lib/docker
container logs:
/var/lib/docker/containers/container_id/xxxx.json.log
#list logs size
find /var/lib/docker/containers/ -name *-json.log |xargs du -sh
#reset log
cat /dev/null >/var/lib/docker/containers/xxxx/xxxx.log-json.log
docker log-driver
/etc/docker/daemon.json
{
"registry-mirrors": [

],
"log-driver": "json-file",
"log-opts": {
"max-size": "100m",

}
systemctl daemon-reload && systemctl restart docker
