Detailed Theory of KUBERNETES:

• KUBERNETES Objects:

Kubernetes Objects:

• Kubernetes uses objects to represent the state of your cluster
• what containerized applications are running ( and on which node)
• The policies around how those applications behave, such as restart policies, upgrades and fault tolerance
• once you create the object, the kubernetes sytem will constantly work to ensure that object exist and maintain’s clusters desired state.
• every kubernetes object includes two nested fields that govern the object config the object spec and the object status
• The spec, which we provide, describes your desired state for the object-the characteristics that you want the object to have
• the status describes the actual state of the object and is supplied and updated by the kubernetes system
• all objects are identified by a unique name and a UID
• The basic kubernetes objects include
  1. Pod
  2. service
  3. volume
  4. namespace
  5. replicasets
  6. secrets
  7. configmaps
  8. deployments
  9. jobs
  10. daemonsets

Relationship between these objects:

• pod manages containers
• replicaset manage pods
• services expose pod processes to the outside world
