-This is just a simple demonstration to get a basic understanding of how kubernetes works while working step by step. I learnt kubernetes like this and made this repo to solve some problems that I faced during my learning experience so that it might help other beginners. We won't be going into depth about docker :blush: but will see sufficient content to get you basic understanding to learn and work with kuberntes. :v: Hope you enjoy learning. If you like it please give it a :star2:.

 **Important :-** By seeing size of readme you might have second thoughts but to be honest if you work from start you won't experience any problem and learn along the way.

 ```
 But setting the *nodeSelector* to a specific node by the hostname label may lead to the pod being unschedulable if the node is offline.
 
+### Annotating pods
+
+In addition to other labels, pods and other objects can also contain annotations. They are also key value pairs, so in essence they are similar to labels, but aren't meant to hold identifying information. They can't be used to group objects the way label can.
+
+Example
+
+`kubeclt get pod -a`
