NAME

6       kubectl create configmap - Create a configmap from a local file, direc‐
7       tory or literal value

SYNOPSIS

12       kubectl create configmap [OPTIONS]
13
14
15

DESCRIPTION

17       Create a configmap based on a file,  directory,  or  specified  literal
18       value.
19
20
21       A single configmap may package one or more key/value pairs.
22
23
24       When  creating a configmap based on a file, the key will default to the
25       basename of the file, and the value will default to the  file  content.
26       If the basename is an invalid key, you may specify an alternate key.
27
28
29       When  creating  a configmap based on a directory, each file whose base‐
30       name is a valid key in the directory will be  packaged  into  the  con‐
31       figmap.   Any  directory entries except regular files are ignored (e.g.
32       subdirectories, symlinks, devices, pipes, etc).
33
34
35

OPTIONS

37       --allow-missing-template-keys=true
38           If true, ignore any errors in templates when a field or map key  is
39       missing  in  the  template.  Only applies to golang and jsonpath output
40       formats.
41
42
43       --append-hash=false
44           Append a hash of the configmap to its name.
45
46
47       --dry-run=false
48           If true, only print the object that would be sent, without  sending
49       it.
50
51
52       --from-env-file=""
53           Specify the path to a file to read lines of key=val pairs to create
54       a configmap (i.e. a Docker .env file).
55
56
57       --from-file=[]
58           Key file can be specified using its file path, in which  case  file
59       basename  will  be  used as configmap key, or optionally with a key and
60       file path, in which case the given key  will  be  used.   Specifying  a
61       directory  will iterate each named file in the directory whose basename
62       is a valid configmap key.
63
64
65       --from-literal=[]
66           Specify a key and  literal  value  to  insert  in  configmap  (i.e.
67       mykey=somevalue)
68
69
70       --generator="configmap/v1"
71           The name of the API generator to use.
72
73
74       -o, --output=""
75           Output    format.    One   of:   json|yaml|name|go-template|go-tem‐
76       plate-file|template|templatefile|jsonpath|jsonpath-file.
77
78
79       --save-config=false
80           If true, the configuration of current object will be saved  in  its
81       annotation.  Otherwise,  the annotation will be unchanged. This flag is
82       useful when you want to perform kubectl apply on  this  object  in  the
83       future.
84
85
86       --template=""
87           Template  string  or  path  to template file to use when -o=go-tem‐
88       plate, -o=go-template-file. The template format is golang  templates  [
89http://golang.org/pkg/text/template/#pkg-overview⟩].
90
91
92       --validate=true
93           If true, use a schema to validate the input before sending it
