6 oc label - Update the labels on a resource
7
11 oc label [OPTIONS]
12
16 Update the labels on one or more resources
17 A valid label value is consisted of letters and/or numbers with a max
20 length of 63 characters. If --overwrite is true, then existing labels
21 can be overwritten, otherwise attempting to overwrite a label will
22 result in an error. If --resource-version is specified, then updates
23 will use this resource version, otherwise the existing resource-version
24 will be used.
25
29 --all=false
30 Select all resources, including uninitialized ones, in the names‐
31 pace of the specified resource types
32 --allow-missing-template-keys=true
35 If true, ignore any errors in templates when a field or map key is
36 missing in the template. Only applies to golang and jsonpath output
37 formats.
38 --dry-run=false
41 If true, only print the object that would be sent, without sending
42 it.
43 --field-selector=""
46 Selector (field query) to filter on, supports '=', '==', and
47 '!='.(e.g. --field-selector key1=value1,key2=value2). The server only
48 supports a limited number of field queries per type.
49 -f, --filename=[]
52 Filename, directory, or URL to files identifying the resource to
53 update the labels
54 --include-uninitialized=false
57 If true, the kubectl command applies to uninitialized objects. If
58 explicitly set to false, this flag overrides other flags that make the
59 kubectl commands apply to uninitialized objects, e.g., "--all". Objects
60 with empty metadata.initializers are regarded as initialized.
61 --list=false
64 If true, display the labels for a given resource.
65 --local=false
68 If true, label will NOT contact api-server but run locally.
69 -o, --output=""
72 Output format. One of: json|yaml|name|template|go-template|go-tem‐
73 plate-file|templatefile|jsonpath|jsonpath-file.
74 --overwrite=false
77 If true, allow labels to be overwritten, otherwise reject label
78 updates that overwrite existing labels.
79 --record=false
82 Record current kubectl command in the resource annotation. If set
83 to false, do not record the command. If set to true, record the com‐
84 mand. If not set, default to updating the existing annotation value
85 only if one already exists.
86 -R, --recursive=false
89 Process the directory used in -f, --filename recursively. Useful
90 when you want to manage related manifests organized within the same
91 directory.
92 --resource-version=""
95 If non-empty, the labels update will only succeed if this is the
96 current resource-version for the object. Only valid when specifying a
97 single resource.
98 -l, --selector=""
101 Selector (label query) to filter on, not including uninitialized
102 ones, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2).
