Kubectl: Get ConfigMap – Kubernetes
In programming, we use .env or separate config files to store settings, configurations or variables separately from the application code.
This permits to run the application in different environments.
A ConfigMap in a Kubernetes is used to achieve the same functionality – it allows to make applications portable by decoupling environment-specific configurations from the containers.
The ConfigMap is a dictionary of configuration settings that consists of key-value pairs.
This note shows how to get the ConfigMap using the kubectl command.
