When some nodes of k8s run for a period of time, an error is reported: sys/FS/CGroup/memory/docker: no space left on device \ “: unknown

The docker’s memory is full, probably because SELinux = is on

Permanent closure solution:

VI/etc/SELinux/config, change SELinux = enforcing to SELinux = disabled, then save and exit

Then restart the computer

The node can be used after re running

Of course, this is: basic entrance examination of intelligent gtalent operation engineer

If it is only used temporarily, then directly: setenforce 0
