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.
--allow-missing-template-keys=true If true, ignore any errors in
templates when a field or map key is missing in the template. Only applies to
golang and jsonpath output formats.
--cascade="background" Must be "background",
"orphan", or "foreground". Selects the deletion cascading
strategy for the dependents (e.g. Pods created by a ReplicationController).
Defaults to background.
--dry-run="none" Must be "none", "server",
or "client". If client strategy, only print the object that would be
sent, without sending it. If server strategy, submit server-side request
without persisting the resource.
--field-manager="kubectl-client-side-apply" Name of the
manager used to track field ownership.
-f, --filename=[] that contains the configuration to apply
--force=false If true, immediately remove resources from API and bypass
graceful deletion. Note that immediate deletion of some resources may result
in inconsistency or data loss and requires confirmation.
--force-conflicts=false If true, server-side apply will force the
changes against conflicts.
--grace-period=-1 Period of time in seconds given to the resource to
terminate gracefully. Ignored if negative. Set to 1 for immediate shutdown.
Can only be set to 0 when --force is true (force deletion).
-k, --kustomize="" Process a kustomization directory.
This flag can't be used together with -f or -R.
--openapi-patch=true If true, use openapi to calculate diff when the
openapi presents and the resource can be found in the openapi spec. Otherwise,
fall back to use baked-in types.
-o, --output="" Output format. One of:
json|yaml|name|go-template|go-template-file|template|templatefile|jsonpath|jsonpath-as-json|jsonpath-file.
--overwrite=true Automatically resolve conflicts between the modified
and live configuration by using values from the modified configuration
--prune=false Automatically delete resource objects, including the
uninitialized ones, 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=[] Overwrite the default whitelist with for --prune
--record=false 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=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)
--server-side=false If true, apply runs in the server instead of the

zero means determine a timeout from the size of the object

sending it

This waits for finalizers.

NAME
kubectl apply - Apply a configuration to a resource by filename or stdinSYNOPSIS
kubectl apply [OPTIONS]DESCRIPTION
Apply a configuration to a resource by filename or stdin. The resource name must be specified. 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'.OPTIONS
--all=false Select all resources in the namespace of the specified resource types.OPTIONS INHERITED FROM PARENT COMMANDS
--add-dir-header=false If true, adds the file directory to the header of the log messagesEXAMPLE
# Apply the configuration in pod.json to a pod. kubectl apply -f ./pod.json # Apply resources from a directory containing kustomization.yaml - e.g. dir/kustomization.yaml. kubectl apply -k dir/ # 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 that are not in the file. kubectl apply --prune -f manifest.yaml --all --prune-whitelist=core/v1/ConfigMap
