Hello everyone, I have a question regarding the certs, what is the main difference between CKA and CKAD? Is it worth to pursue both certs or one is enough? thanks for your help
My humble advice will be: Aim for one initially…Once you have passed your first exam, then you re-assess to see if you still have the fire inside you to continue…
Depends what you role is and what you looking for. If you work with k8s daily I would say get all 3, otherwise just CKA & CKS.
CKA is administering a Cluster (Basic Usage, How K8s Works, etc…). Great if you go somewhere where you need to manage a KOPS/Manual Cluster.
CKAD is more focussed towards developers. More indepth focus around create pods with init containers, volume mounts, multi-container pods, probes, deployments, services etc…
CKS is more focused on Security. CKA cert is a pre-requisite. Focused on securing your Clusters (RBAC, Encrypting etcd, image scanning, auditing etc…).
I’ve done CKA and CKAD. Writing CKS early May.
