Details

• ConfigMap

    A ConfigMap is an API object used to store non-confidential data in key-value pairs, can be consumed as a as environment variables in pods.
  

• Secret

  A Secret is an object that contains a small amount of confidential data such as a password, a token, or a key. Such information might otherwise be put in a Pod specification or in a container image.
  

• Deployment

  A Deployment provides declarative updates for Pods and ReplicaSets.
  
  You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. You can define Deployments to create new ReplicaSets,
  or to remove existing Deployments and adopt all their resources with new Deployments.      
  

• Service

  An abstract way to expose an application running on a set of Pods as a network service.
