19 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
26
27
29 --all=false
30 Select all resources, including uninitialized ones, in the names‐
31 pace of the specified resource types
32
33
34 --allow-missing-template-keys=true

52 Filename, directory, or URL to files identifying the resource to
53 update the labels
54

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
62
63 --list=false

78 updates that overwrite existing labels.

85 only if one already exists.
86

99
100 -l, --selector=""
101 Selector (label query) to filter on, not including uninitialized
