Hands-On: Creating ConfigMaps Imperatively

As with most Kubernetes objects, you can create them imperatively and declaratively. We’ll look at the imperative method first.

The command to imperatively create a ConfigMap is kubectl create configmap, but you can shorten configmap to cm. The command accepts two sources of data:

• literal values on the command line (--from-literal)
• files referenced on the command line (--from-file)

Run the following command to create a, ConfigMap called testmap1, populated with two map entries from literal values passed on the command line.
