kubectl apply
kubectl apply
Apply a configuration to a resource by filename or stdin
Synopsis
Apply a configuration to a resource by filename or stdin. This resource will be created if it doesn’t exist yet. To use ‘apply’, always create the resource initially with either ‘apply’ or ‘create –save-config’.
JSON and YAML formats are accepted.
Alpha Disclaimer: the –prune functionality is not yet complete. Do not use unless you are aware of what the current state is. See https://issues.k8s.io/34274.
kubectl apply -f FILENAME
Examples
# Apply the configuration in pod.json to a pod.
kubectl apply -f ./pod.json
# Apply the JSON passed into stdin to a pod.
cat pod.json | kubectl apply -f -
# Note: --prune is still in Alpha
# Apply the configuration in manifest.yaml that matches label app=nginx and delete all the other resources that are not in the file and match label app=nginx.
kubectl apply --prune -f manifest.yaml -l app=nginx
# Apply the configuration in manifest.yaml and delete all the other configmaps with the same label key that are not in the file.
kubectl apply --prune -f manifest.yaml --all --prune-whitelist=core/v1/ConfigMap
Options
--all [-all] to select all the specified resources.
--cascade Only relevant during a prune or a force apply. If true, cascade the deletion of the resources managed by pruned or deleted resources (e.g. Pods created by a ReplicationController). (default true)
--dry-run If true, only print the object that would be sent, without sending it.
-f, --filename stringSlice Filename, directory, or URL to files that contains the configuration to apply
--force Delete and re-create the specified resource, when PATCH encounters conflict and has retried for 5 times.
--grace-period int Only relevant during a prune or a force apply. Period of time in seconds given to pruned or deleted resources to terminate gracefully. Ignored if negative. (default -1)
--no-headers When using the default or custom-column output format, don't print headers.
-o, --output string Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
--output-version string Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
--overwrite Automatically resolve conflicts between the modified and live configuration by using values from the modified configuration (default true)
--prune Automatically delete resource objects that do not appear in the configs and are created by either apply or create --save-config. Should be used with either -l or --all.
--prune-whitelist stringArray Overwrite the default whitelist with <group/version/kind> for --prune
--record Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists.
-R, --recursive Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
--schema-cache-dir string If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema' (default "~/.kube/schema")
-l, --selector string Selector (label query) to filter on
-a, --show-all When printing, show all resources (default hide terminated pods.)
--show-labels When printing, show all labels as the last column (default hide labels column)
--sort-by string If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
--template string Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].
--timeout duration Only relevant during a force apply. The length of time to wait before giving up on a delete of the old resource, zero means determine a timeout from the size of the object. Any other values should contain a corresponding time unit (e.g. 1s, 2m, 3h).
--validate If true, use a schema to validate the input before sending it (default true)
Options inherited from parent commands
--alsologtostderr log to standard error as well as files
--as string Username to impersonate for the operation
--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
--context string The name of the kubeconfig context to use
--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.
--log-backtrace-at traceLocation when logging hits line file:N, emit a stack trace (default :0)
--log-dir string If non-empty, write log files in this directory
--logtostderr log to standard error instead of files
--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
--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
--stderrthreshold severity logs at or above this threshold go to stderr (default 2)
--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
-v, --v Level log level for V logs
--vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging
