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.
Syntax
werf kubectl diff -f FILENAME [options]
Examples
# Diff resources included in pod.json
kubectl diff -f pod.json
# Diff file read from stdin
cat service.yaml | kubectl diff -f -
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 whitelist 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
--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='~/.kube/cache'

--home-dir=''

HTTPS connections insecure (default $WERF_SKIP_TLS_VERIFY_REGISTRY)

Kubernetes config data as base64 string (default $WERF_KUBE_CONFIG_BASE64 or
$WERF_KUBECONFIG_BASE64 or $KUBECONFIG_BASE64)
--kubeconfig=''
Path to the kubeconfig file to use for CLI requests (default $WERF_KUBE_CONFIG, or

--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
