Apply a configuration to a resource by file name 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'.
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.
Examples:
# 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 -
# Apply the configuration from all files that end with '.json' - i.e. expand wildcard characters
in file names
kubectl apply -f '*.json'
# Note: --prune is still in Alpha
# Apply the configuration in manifest.yaml that matches label app=nginx and delete all 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 config maps that are not in
the file
kubectl apply --prune -f manifest.yaml --all --prune-whitelist=core/v1/ConfigMap
Available Commands:
edit-last-applied Edit latest last-applied-configuration annotations of a resource/object
set-last-applied Set the last-applied-configuration annotation on a live object to match the
contents of a file
view-last-applied View the latest last-applied-configuration annotations of a resource/object
Options:
--all=false:
Select all resources in the namespace of the specified resource types.
--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, 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 <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, keep the managedFields when printing objects in JSON or YAML format.
--template='':
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=0s:
The length of time to wait before giving up on a delete, zero means determine a timeout
from the size of the object
--validate='strict':
Must be one of: strict (or true), warn, ignore (or false). "true" or "strict" will use a
schema to validate the input and fail the request if invalid. It will perform server side
validation if ServerSideFieldValidation is enabled on the api-server, but will fall back
to less reliable client-side validation if not. "warn" will warn about unknown or
duplicate fields without blocking the request if server-side field validation is enabled
on the API server, and behave as "ignore" otherwise. "false" or "ignore" will not
perform any schema validation, silently dropping any unknown or duplicate fields.
--wait=false:
If true, wait for resources to be gone before returning. This waits for finalizers.
Usage:
kubectl apply (-f FILENAME | -k DIRECTORY) [options]
Use "kubectl <command> --help" for more information about a given command.
Use "kubectl options" for a list of global command-line options (applies to all commands).
