NAME¶
oc diff - Diff the live version against a would-be applied version
SYNOPSIS¶
oc diff [OPTIONS]
DESCRIPTION¶
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.
OPTIONS¶
--concurrency=1
Number of objects to process in parallel when diffing against the live
version. Larger number = faster, but more memory, I/O and CPU over that
shorter period of time.
--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.
--prune=false
Include resources that would be deleted by pruning. Can be used with -l and
default shows all resources would be pruned
--prune-allowlist=[]
Overwrite the default allowlist with <group/version/kind> for
--prune
-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). Matching objects must satisfy all of the specified
label constraints.
--server-side=false
If true, apply runs in the server instead of the client.
--show-managed-fields=false
If true, include managed fields in the diff.
OPTIONS INHERITED FROM PARENT COMMANDS¶

--match-server-version=false
Require server version to match client version
-n, --namespace=""
If present, the namespace scope for this CLI request
--profile="none"
Name of profile to capture. One of
(none|cpu|heap|goroutine|threadcreate|block|mutex)
--profile-output="profile.pprof"
Name of the file to write the profile to
--request-timeout="0"
The length of time to wait before giving up on a single server request.
