Diff the live version against a would-be applied version
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.
ergo kubectl diff -f FILENAME
# Diff resources included in pod.json
kubectl diff -f pod.json
# Diff file read from stdin
cat service.yaml | kubectl diff -f -
--field-manager string Name of the manager used to track field ownership. (default "kubectl-client-side-apply")
-f, --filename strings Filename, directory, or URL to files contains the configuration to diff
--force-conflicts If true, server-side apply will force the changes against conflicts.
-h, --help help for diff
-k, --kustomize string Process the kustomization directory. This flag can't be used together with -f or -R.
--prune Include resources that would be deleted by pruning. Can be used with -l and default shows all resources would be pruned
--prune-allowlist stringArray Overwrite the default whitelist with <group/version/kind> for --prune
-R, --recursive Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
-l, --selector string 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 If true, apply runs in the server instead of the client.
--show-managed-fields If true, include managed fields in the diff.
--as string Username to impersonate for the operation. User could be a regular user or a service account in a namespace.
--as-group stringArray Group to impersonate for the operation, this flag can be repeated to specify multiple groups.
--as-uid string UID to impersonate for the operation.
--cache-dir string Default cache directory (default "/Users/ysicing/.kube/cache")
--certificate-authority string Path to a cert file for the certificate authority
--client-certificate string Path to a client certificate file for TLS
--client-key string Path to a client key file for TLS
--cluster string The name of the kubeconfig cluster to use
--config string The ergo config file to use (default "/Users/ysicing/.ergo/config/ergo.yml")
--context string The name of the kubeconfig context to use
--debug Prints the stack trace if an error occurs
--disable-compression If true, opt-out of response compression for all requests to the server
--insecure-skip-tls-verify If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
--kubeconfig string Path to the kubeconfig file to use for CLI requests.
--match-server-version Require server version to match client version
-n, --namespace string If present, the namespace scope for this CLI request
--password string Password for basic authentication to the API server
--profile string Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex) (default "none")
--profile-output string Name of the file to write the profile to (default "profile.pprof")
--request-timeout string 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. (default "0")
-s, --server string The address and port of the Kubernetes API server
--silent Run in silent mode and prevents any ergo log output except panics & fatals
--tls-server-name string Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used
--token string Bearer token for authentication to the API server
--user string The name of the kubeconfig user to use
--username string Username for basic authentication to the API server
--warnings-as-errors Treat warnings received from the server as errors and exit with a non-zero exit code
- ergo kubectl - Kubectl controls the Kubernetes cluster manager
