| Tips to pass Certified Kubernetes Application Developer (CKAD) exam | |
| Getting started Kubernetes :- | |
| a) Book : Kubernetes: Up & Running | |
| b) Practice practice & practice with CKAD Exercises | |
| the Best Kubernetes CKAD sample exercises which cover all parts of the exam https://github.com/dgkanatsios/CKAD-exercises. | |

| e) Whether or not you use Kubernetes at work, you should still provision your own cluster somewhere and play with it. |
