Kubernetes is a powerful tool. It can help you manage complex applications and provide you with the ability to easily automate tasks involved in managing them. In this course, we will start exploring Kubernetes from a beginner's standpoint. We will discuss what Kubernetes is and what it does, and we will work with some of the basic functionality of Kubernetes hands-on. We will build a simple Kubernetes cluster. We will also deploy a sample microservice application to the cluster in order to explore how Kubernetes can help easily manage such applications.

A Practical Guide to Kubernetes

# Creating ConfigMap Using Literals

Hopefully, even when our applications need different configs to work in distinct clusters, the differences are limited. Often, they should be limited to only a few key/value entries. In such cases, it might be easier to create ConfigMaps using `--from-literal`.

Let's take a look at an example.

kubectl create cm my-config \
    --from-literal=something=else \
    --from-literal=weather=sunny

kubectl get cm my-config -o yaml

The **output** of the latter command is as follows (`metadata` is removed for brevity).

In this lesson, we will go through injecting configurations from key/value literals.
