Diff configurations specified by file name or stdin between the current online configuration, and the configuration as it would be if applied.
The output is always YAML.
KUBECTL_EXTERNAL_DIFF environment variable can be used to select your own diff command. Users can use external commands with params too, example: KUBECTL_EXTERNAL_DIFF="colordiff -N -u"
By default, the "diff" command available in your path will be run with the "-u" (unified diff) and "-N" (treat absent files as empty) options.
Exit status: 0 No differences were found. 1 Differences were found. >1 Kubectl or diff failed with an error.
Note: KUBECTL_EXTERNAL_DIFF, if used, is expected to follow that convention.

--field-manager='kubectl-client-side-apply' Name of the manager used to track field ownership. -f, --filename= Filename, directory, or URL to files contains the configuration to diff --force-conflicts=false If true, server-side apply will force the changes against conflicts. -k, --kustomize='' Process the kustomization directory. This flag can`t be used together with -f or -R. -R, --recursive=false Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory. -l, --selector='' Selector (label query) to filter on, supports `=`, `==`, and `!=`.(e.g. -l key1=value1,key2=value2) --server-side=false If true, apply runs in the server instead of the client.
