DESCRIPTION

16       Diff configurations specified by filename or stdin between the current
17       online configuration, and the configuration as it would be if applied.
18

21
22
23       KUBECTL_EXTERNAL_DIFF environment variable can be used to select your
24       own diff command. By default, the "diff" command available in your path
25       will be run with "-u" (unified diff) and "-N" (treat absent files as
26       empty) options.
27
28
29       Exit status: 0 No differences were found. 1 Differences were found. >1
30       Kubectl or diff failed with an error.
31
