6 kubectl create configmap - Create a configmap from a local file,
7 directory or literal value
8
12 kubectl create configmap [OPTIONS]
13
17 Create a configmap based on a file, directory, or specified literal
18 value.
19 A single configmap may package one or more key/value pairs.
22 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 When creating a configmap based on a directory, each file whose
30 basename is a valid key in the directory will be packaged into the
31 configmap. Any directory entries except regular files are ignored
32 (e.g. subdirectories, symlinks, devices, pipes, etc).
33
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 --append-hash=false
44 Append a hash of the configmap to its name.
45 --dry-run="none"
48 Must be "none", "server", or "client". If client strategy, only
49 print the object that would be sent, without sending it. If server
50 strategy, submit server-side request without persisting the resource.
51 --from-env-file=""
54 Specify the path to a file to read lines of key=val pairs to create
55 a configmap (i.e. a Docker .env file).
56 --from-file=[]
59 Key file can be specified using its file path, in which case file
60 basename will be used as configmap key, or optionally with a key and
61 file path, in which case the given key will be used. Specifying a
62 directory will iterate each named file in the directory whose basename
63 is a valid configmap key.
64 --from-literal=[]
67 Specify a key and literal value to insert in configmap (i.e.
68 mykey=somevalue)
69 --generator="configmap/v1"
72 The name of the API generator to use.

78 --save-config=false
81 If true, the configuration of current object will be saved in its
82 annotation. Otherwise, the annotation will be unchanged. This flag is
83 useful when you want to perform kubectl apply on this object in the
84 future.
85 --template=""
88 Template string or path to template file to use when
89 -o=go-template, -o=go-template-file. The template format is golang
