Is there a way to run kubectl diff -f . in that way so that output shows only file names that would be changed with kubectl apply -f . and not every single diff line...?

CodePudding user response：

You can use, something as below, here KUBECTL_EXTERNAL_DIFF is an env variable, to use a custom diff program with custom flags. So, basically, here we are telling kubectl to use diff -qr for displaying the difference. By default, kubectl use diff -u -N.

KUBECTL_EXTERNAL_DIFF='diff -qr' kubectl diff -f .
