19 Diff configurations specified by filename or stdin between the current

21 Output is always YAML.
24 KUBECTL_EXTERNAL_DIFF environment variable can be used to select your
27 own diff command. Users can use external commands with params too, ex‐
28 ample: KUBECTL_EXTERNAL_DIFF="colordiff -N -u"
29 By default, the "diff" command available in your path will be run with
32 "-u" (unified diff) and "-N" (treat absent files as empty) options.
33 Exit status: 0 No differences were found. 1 Differences were found. >1
36 Kubectl or diff failed with an error.
37 Note: KUBECTL_EXTERNAL_DIFF, if used, is expected to follow that con‐
40 vention.
