If your docker disk usage is too large, try this:
1. Find the cointainer which has a large size:
docker system df -v
2. Use that container in the command below:
docker exec <container> /bin/bash -c 'rm -rf /tmp/.*'
That saved me >37GB.

Docker Forum.)
P.S. to exclude
. and
.. and avoid warning messages, you can use:
docker exec <container> /bin/bash -c 'rm -rf tmp/.[!.]* tmp/..?* tmp/*'
