6 kubectl delete - Delete resources by filenames, stdin, resources and
7 names, or by resources and label selector
8
12 kubectl delete [OPTIONS]
13
17 Delete resources by filenames, stdin, resources and names, or by
18 resources and label selector.
19 JSON and YAML formats are accepted. Only one type of the arguments may
22 be specified: filenames, resources and names, or resources and label
23 selector.
24 Some resources, such as pods, support graceful deletion. These
27 resources define a default period before they are forcibly terminated
28 (the grace period) but you may override that value with the
29 --grace-period flag, or pass --now to set a grace-period of 1. Because
30 these resources often represent entities in the cluster, deletion may
31 not be acknowledged immediately. If the node hosting a pod is down or
32 cannot reach the API server, termination may take significantly longer
33 than the grace period. To force delete a resource, you must pass a
34 grace period of 0 and specify the --force flag.
35 IMPORTANT: Force deleting pods does not wait for confirmation that the
38 pod's processes have been terminated, which can leave those processes
39 running until the node detects the deletion and completes graceful
40 deletion. If your processes use shared storage or talk to a remote API
41 and depend on the name of the pod to identify themselves, force delet‐
42 ing those pods may result in multiple processes running on different
43 machines using the same identification which may lead to data corrup‐
44 tion or inconsistency. Only force delete pods when you are sure the pod
45 is terminated, or if your application can tolerate multiple copies of
46 the same pod running at once. Also, if you force delete pods the sched‐
47 uler may place new pods on those nodes before the node has released
48 those resources and causing those pods to be evicted immediately.
49 Note that the delete command does NOT do resource version checks, so if
52 someone submits an update to a resource right when you submit a delete,
53 their update will be lost along with the rest of the resource.
54
58 --all=false
59 Delete all resources, including uninitialized ones, in the names‐
60 pace of the specified resource types.
61 --cascade=true
64 If true, cascade the deletion of the resources managed by this
65 resource (e.g. Pods created by a ReplicationController). Default true.
66 --field-selector=""
69 Selector (field query) to filter on, supports '=', '==', and
70 '!='.(e.g. --field-selector key1=value1,key2=value2). The server only
71 supports a limited number of field queries per type.
72 -f, --filename=[]
75 containing the resource to delete.
76 --force=false
79 Only used when grace-period=0. If true, immediately remove
80 resources from API and bypass graceful deletion. Note that immediate
81 deletion of some resources may result in inconsistency or data loss and
82 requires confirmation.
83 --grace-period=-1
86 Period of time in seconds given to the resource to terminate grace‐
87 fully. Ignored if negative. Set to 1 for immediate shutdown. Can only
88 be set to 0 when --force is true (force deletion).
89 --ignore-not-found=false
92 Treat "resource not found" as a successful delete. Defaults to
93 "true" when --all is specified.
94 --include-uninitialized=false
97 If true, the kubectl command applies to uninitialized objects. If
98 explicitly set to false, this flag overrides other flags that make the
99 kubectl commands apply to uninitialized objects, e.g., "--all". Objects
100 with empty metadata.initializers are regarded as initialized.
101 --now=false
104 If true, resources are signaled for immediate shutdown (same as
105 --grace-period=1).
106 -o, --output=""
109 Output mode. Use "-o name" for shorter output (resource/name).
110 -R, --recursive=false
113 Process the directory used in -f, --filename recursively. Useful
114 when you want to manage related manifests organized within the same
115 directory.
116 -l, --selector=""
119 Selector (label query) to filter on, not including uninitialized
120 ones.
121 --timeout=0s
124 The length of time to wait before giving up on a delete, zero means
125 determine a timeout from the size of the object
126 --wait=true

130 for finalizers.
