How to update Sysctl settings with
fs.inotify.max_user_watches=1048576
You can check the current inotify user instance limit, with the following:
cat /proc/sys/fs/inotify/max_user_instances
Similarly, the current inotify user watch limit can be checked as follows:
cat /proc/sys/fs/inotify/max_user_watches
Update the limits You can update the limits temporarily, with the following commands (setting the values to 8192 and 524288 respectively in this example):
sudo sysctl fs.inotify.max_user_instances=8192
sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl -p
In order to make the changes permanent, i.e. to persist a reboot, you can set fs.inotify.max_user_instances=8192 and fs.inotify.max_user_watches=524288 in the file /etc/sysctl.conf.
After updating the limits, you can validate these on the host again, as above, with cat /proc/sys/fs/inotify/max_user_instances and cat /proc/sys/fs/inotify/max_user_watches.
