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 '=', '==', '!=', 'in', 'notin'.(e.g. -l key1=value1,key2=value2,key3 in (value3)). 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

EXAMPLE

     # Diff resources included in pod.json
     kubectl diff -f pod.json

     # Diff file read from stdin
     cat service.yaml | kubectl diff -f -
