By default, image-gc-high-threshold and image-gc-low-threshold values are 90 and 80% respectively.
We want to change them to 80 and 70, How we can change the Kubernetes image garbage collection threshold values.
Thanks in advance.
Changing the garbage collection thresholds can be done using switches on the kubelet.
From the docs
--image-gc-high-threshold int32 The percent of disk usage after which image garbage collection is always run. (default 85)
--image-gc-low-threshold int32 The percent of disk usage before which image garbage collection is never run. Lowest disk usage to garbage collect to. (default 80)Essentially you can override default user values as described in the documentation below.
