Delete resources by file names, stdin, resources and names, or by resources and label selector.
JSON and YAML formats are accepted. Only one type of argument may be specified: file names, resources and names, or resources and label selector. Some resources, such as pods, support graceful deletion. These resources define a default period before they are forcibly terminated (the grace period) but you may override that value with the --grace-period flag, or pass --now to set a grace-period of 1. Because these resources often represent entities in the cluster, deletion may not be acknowledged immediately. If the node hosting a pod is down or cannot reach the API server, termination may take significantly longer than the grace period. To force delete a resource, you must specify the --force flag. Note: only a subset of resources support graceful deletion. In absence of the support, the --grace-period flag is ignored.
IMPORTANT: Force deleting pods does not wait for confirmation that the pod’s processes have been terminated, which can leave those processes running until the node detects the deletion and completes graceful deletion. If your processes use shared storage or talk to a remote API and depend on the name of the pod to identify themselves, force deleting those pods may result in multiple processes running on different machines using the same identification which may lead to data corruption or inconsistency. Only force delete pods when you are sure the pod is terminated, or if your application can tolerate multiple copies of the same pod running at once. Also, if you force delete pods, the scheduler may place new pods on those nodes before the node has released those resources and causing those pods to be evicted immediately.
Note that the delete command does NOT do resource version checks, so if someone submits an update to a resource right when you submit a delete, their update will be lost along with the rest of the resource.
Syntax
werf kubectl delete ([-f FILENAME] | [-k DIRECTORY] | TYPE [(NAME | -l label | --all)]) [options]
Examples
# Delete a pod using the type and name specified in pod.json
kubectl delete -f ./pod.json
# Delete resources from a directory containing kustomization.yaml - e.g. dir/kustomization.yaml
kubectl delete -k dir
# Delete resources from all files that end with '.json'
kubectl delete -f '*.json'
# Delete a pod based on the type and name in the JSON passed into stdin
cat pod.json | kubectl delete -f -
# Delete pods and services with same names "baz" and "foo"
kubectl delete pod,service baz foo
# Delete pods and services with label name=myLabel
kubectl delete pods,services -l name=myLabel
# Delete a pod with minimal delay
kubectl delete pod foo --now
# Force delete a pod on a dead node
kubectl delete pod foo --force
# Delete all pods
kubectl delete pods --all
Options
--all=false
Delete all resources, in the namespace of the specified resource types.
-A, --all-namespaces=false
If present, list the requested object(s) across all namespaces. Namespace in current
context is ignored even if specified with --namespace.
--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-selector=''
Selector (field query) to filter on, supports `=`, `==`, and `!=`.(e.g.
--field-selector key1=value1,key2=value2). The server only supports a limited number of
field queries per type.
-f, --filename=[]
containing the resource to delete.
--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.
--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).
--ignore-not-found=false
Treat "resource not found" as a successful delete. Defaults to "true" when --all is
specified.
-i, --interactive=false
If true, delete resource only when user confirms. This flag is in Alpha.
-k, --kustomize=''
Process a kustomization directory. This flag can`t be used together with -f or -R.
--now=false
If true, resources are signaled for immediate shutdown (same as --grace-period=1).
-o, --output=''
Output mode. Use "-o name" for shorter output (resource/name).
--raw=''
Raw URI to DELETE to the server. Uses the transport specified by the kubeconfig file.
-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.
--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
--wait=true
If true, wait for resources to be gone before returning. This waits for finalizers.
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'
Default cache directory
--certificate-authority=''
Path to a cert file for the certificate authority
--client-certificate=''
Path to a client certificate file for TLS
--client-key=''
Path to a client key file for TLS
--cluster=''
The name of the kubeconfig cluster to use
--context=''
The name of the kubeconfig context to use (default $WERF_KUBE_CONTEXT)
--disable-compression=false
If true, opt-out of response compression for all requests to the server
--home-dir=''
Use specified dir to store werf cache files and dirs (default $WERF_HOME or ~/.werf)
--insecure-skip-tls-verify=false
If true, the server`s certificate will not be checked for validity. This will make your
HTTPS connections insecure (default $WERF_SKIP_TLS_VERIFY_REGISTRY)
--kube-config-base64=''
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
$WERF_KUBECONFIG, or $KUBECONFIG). Ignored if kubeconfig passed as base64.
--log-flush-frequency=5s
Maximum number of seconds between log flushes
--match-server-version=false
Require server version to match client version
-n, --namespace=''
If present, the namespace scope for this CLI request
--password=''
Password for basic authentication to the API server
--profile='none'
Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex)
--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
timeout requests.

--warnings-as-errors=false
