How to list docker logs size for all containers?

Question

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.

Answer 1

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"

Answer 2

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).
