Hands-On: Creating ConfigMaps Imperatively

As with most Kubernetes resources, we can create ConfigMaps imperatively and declaratively. We’ll look at the imperative method first.

Creating ConfigMaps

We create ConfigMaps imperatively with the kubectl create configmap command. However, we can shorten configmap to cm, and the command accepts two sources of data:

• Literal values on the command line (--from-literal)

• Files (--from-file)

Use the following terminal to run all the commands from this lesson.
