NAME
kubectl diff - Diff the live version against a would-be applied version
SYNOPSIS
kubectl 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 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
--as="" Username to impersonate for the operation. User could be a regular user or a service account in a namespace.
--as-group=[] Group to impersonate for the operation, this flag can be repeated to specify multiple groups.
--as-uid="" UID to impersonate for the operation.
--cache-dir="/home/username/.kube/cache" Default cache directory
--certificate-authority="" Path to a cert file for the certificate authority
--client-certificate="" Path to a client certificate file for TLS
--client-key="" Path to a client key file for TLS
--cluster="" The name of the kubeconfig cluster to use
--context="" The name of the kubeconfig context to use
--disable-compression=false If true, opt-out of response compression for all requests to the server
--insecure-skip-tls-verify=false If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
--kubeconfig="" Path to the kubeconfig file to use for CLI requests.
--match-server-version=false Require server version to match client version
-n, --namespace="" If present, the namespace scope for this CLI request
--password="" Password for basic authentication to the API server
--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. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.
-s, --server="" The address and port of the Kubernetes API server
--tls-server-name="" Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used
--token="" Bearer token for authentication to the API server
--user="" The name of the kubeconfig user to use
--username="" Username for basic authentication to the API server
--version=false --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version
--warnings-as-errors=false Treat warnings received from the server as errors and exit with a non-zero exit code
