kubectl create configmap — Create a configmap from a local file, directory or literal value

Synopsis

kubectl create configmap [Options]

Description

Create a configmap based on a file, directory, or specified literal value.

A single configmap may package one or more key/value pairs.

When creating a configmap based on a file, the key will default to the basename of the file, and the value will default to the file content.  If the basename is an invalid key, you may specify an alternate key.

When creating a configmap based on a directory, each file whose basename is a valid key in the directory will be packaged into the configmap.  Any directory entries except regular files are ignored (e.g. subdirectories, symlinks, devices, pipes, etc).

Options

--allow-missing-template-keys=true

If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats.

--append-hash=false

Append a hash of the configmap to its name.

--dry-run=false

If true, only print the object that would be sent, without sending it.

--from-env-file=""

Specify the path to a file to read lines of key=val pairs to create a configmap (i.e. a Docker .env file).

--from-file=[]

Key file can be specified using its file path, in which case file basename will be used as configmap key, or optionally with a key and file path, in which case the given key will be used.  Specifying a directory will iterate each named file in the directory whose basename is a valid configmap key.

--from-literal=[]

Specify a key and literal value to insert in configmap (i.e. mykey=somevalue)

--generator="configmap/v1"

The name of the API generator to use.

--no-headers=false

When using the default or custom-column output format, don't print headers (default print headers).

--openapi-validation=true

If true, use openapi rather than swagger for validation.

-o, --output=""

Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [ ⟨http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns⟩], golang template [ ⟨http://golang.org/pkg/text/template/#pkg-overview⟩] and jsonpath template [ ⟨http://kubernetes.io/docs/user-guide/jsonpath⟩].

--output-version=""

DEPRECATED: To use a specific API version, fully-qualify the resource, version, and group (for example: 'jobs.v1.batch/myjob').

--save-config=false

If true, the configuration of current object will be saved in its annotation. Otherwise, the annotation will be unchanged. This flag is useful when you want to perform kubectl apply on this object in the future.

--schema-cache-dir=" /.kube/schema"

If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema'

-a, --show-all=false

When printing, show all resources (default hide terminated pods.)

--show-labels=false

When printing, show all labels as the last column (default hide labels column)

--sort-by=""

If non-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.

--template=""

Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [ ⟨http://golang.org/pkg/text/template/#pkg-overview⟩].

--validate=true

If true, use a schema to validate the input before sending it
