What is ConfigMap in Kubernetes

Question

Hi Guys,

I am new to Kubernetes. I have launched one pod. But I am confused between secret and ConfigMap. Can anyone tell me what is ConfigMap?

Hi@akhtar,

A ConfigMap is an API object used to store non-confidential data in key-value pairs. Pods can consume ConfigMaps as environment variables, command-line arguments, or as configuration files in a volume.

A ConfigMap allows you to decouple environment-specific configuration from your container images so that your applications are easily portable.

ConfigMap does not provide secrecy or encryption. If the data you want to store are confidential, use a Secret rather than a ConfigMap, or use additional (third party) tools to keep your data private.
