How to list docker logs size for all containers?

If you do docker container ls --size it doesn't show the size of the logs, which might be taking all your space and you don't even know.

Size of logs for each docker container, sorted by size:

# without total:
sudo du -h  $(docker inspect --format='{{.LogPath}}' $(docker ps -qa)) | sort -h

# with total:
sudo du -ch $(docker inspect --format='{{.LogPath}}' $(docker ps -qa)) | sort -h

Total size of all docker containers logs in one line:

# human-readable:
sudo du -ch $(docker inspect --format='{{.LogPath}}' $(docker ps -qa)) | tail -n1

# in Mbytes (suitable for monitoring scripts):
sudo du -cm $(docker inspect --format='{{.LogPath}}' $(docker ps -qa)) | tail -n1

Will cause error if you don't have any docker containers (docker ps -qa output is empty).

sudo du -ch $(docker inspect --format='{{.LogPath}}' $(docker ps -qa)) | sort -h | sed 's/\/var\/lib\/docker\/containers\///' | awk '{if ($1 != "total") {split($NF, arr, "/"); id = arr[1]; print $1 " " $2 " " id} else {print $1 " " $2 " " $1}}' | while read size unit id; do if [ "$size" != "total" ]; then name=$(docker ps --format "{{.Names}}" --filter id=$id); echo "$size $unit $name"; else echo "$size $unit $id"; fi; done

for anyone wanting to know what container is filling the docker logs here is a command that will end each line with the container

Here is the command

sudo du -h $(docker inspect --format='{{.LogPath}}' $(docker ps -qa))

Also a good way to prevent logs from taking all your space is to add this to your docker-compose

logging:
  driver: "json-file"
  options:
    max-size: "100m"
    max-file: "5"
