problem
cat /proc/sys/fs/file-nr
6304 0 97745

solution:
sysctl -w fs.file-max=1024000

Create a file named /etc/docker/daemon.json if it does not exist, and add the “userland-proxy”: false setting. The daemon.json file should be valid JSON; if this is the only configuration in that file, it should look like;

{
“userland-proxy”: false
}
After saving the file, restart the daemon using (if your host uses systemd);

sudo systemctl restart docker
Note: On Docker for Mac and Docker for Windows, the userland-proxy cannot be disabled, as it is an essential part of the networking (i.e. it allows connections to localhost to be forwarded to the containers)
