Kubernetes Configmap for Beginners
-------------------------------------------------------------
*ConfigMap*

A ConfigMap is an API object used to store *non-confidential* data in key-value pairs.

Pods](https://kubernetes.io/docs/concepts/w... consume ConfigMaps as environment variables.

A ConfigMap allows you to decouple environment-specific configuration from your [container images](https://kubernetes.io/docs/reference/..., so that your applications are easily portable

```jsx
kubectl create configmap configmap-name --from-literal=key=value --from-literal=key=value
kubectl get configmap configmap-name -o yaml

kubectl edit configmap configmap-name

kubectl create configmap configmap-name --from-file=file-path
kubectl delete configmap configmap-name
```

```jsx
kubectl create configmap my-config --from-literal=DATABASE_HOST=localhost --from-literal=DATABASE_PORT=5432

containers:
name: mycontainer
image: myimage
env:
name: DATABASE_HOST
