9 kubectl create configmap - Create a configmap from a local file, direc‐
10 tory or literal value
11
15 kubectl create configmap [OPTIONS]
16
20 Create a configmap based on a file, directory, or specified literal
21 value.
22 A single configmap may package one or more key/value pairs.
25 When creating a configmap based on a file, the key will default to the
28 basename of the file, and the value will default to the file content.
29 If the basename is an invalid key, you may specify an alternate key.
30 When creating a configmap based on a directory, each file whose base‐
33 name is a valid key in the directory will be packaged into the con‐
34 figmap. Any directory entries except regular files are ignored (e.g.
35 subdirectories, symlinks, devices, pipes, etc).
36
40 --allow-missing-template-keys=true If true, ignore any errors in
41 templates when a field or map key is missing in the template. Only ap‐
42 plies to golang and jsonpath output formats.
43 --append-hash=false Append a hash of the configmap to its name.
46 --dry-run="none" Must be "none", "server", or "client". If client
49 strategy, only print the object that would be sent, without sending it.
50 If server strategy, submit server-side request without persisting the
51 resource.
52 --field-manager="kubectl-create" Name of the manager used to track
55 field ownership.
56 --from-env-file="" Specify the path to a file to read lines of
59 key=val pairs to create a configmap (i.e. a Docker .env file).
60 --from-file=[] Key file can be specified using its file path, in
63 which case file basename will be used as configmap key, or optionally
64 with a key and file path, in which case the given key will be used.
65 Specifying a directory will iterate each named file in the directory
66 whose basename is a valid configmap key.
67 --from-literal=[] Specify a key and literal value to insert in
70 configmap (i.e. mykey=somevalue)
71 --generator="configmap/v1" The name of the API generator to use.
74 -o, --output="" Output format. One of: json|yaml|name|go-tem‐
77 plate|go-template-file|template|templatefile|jsonpath|json‐
78 path-as-json|jsonpath-file.
79 --save-config=false If true, the configuration of current object
82 will be saved in its annotation. Otherwise, the annotation will be un‐
83 changed. This flag is useful when you want to perform kubectl apply on
84 this object in the future.
85 --template="" Template string or path to template file to use when
88 -o=go-template, -o=go-template-file. The template format is golang tem‐
89 plates [http://golang.org/pkg/text/template/#pkg-overview].

93 sending it
