3x Certified Kubernetes in one month
As you know, Kubernetes is the most popular containers orchestrator and it’s used by all Cloud Provider. Therefore the job market demands even more certified engineers.
Today, I’m writing this story to share with you my journey to be 3x Certified Kubernetes (#CKA, #CKAD, #CKS) in only one month.
Choose your platform to learn
I don’t really believe that one platform is the best place to learn all subjects, There is a bunch of good and bad courses in any learning platform
Stop watching course like series
When we start learning for Kubernetes certifications, there is only one key to succeed “practice, practice and practice”, because this is not a QCM exam like other certifications, we’re talking about real problems, bugs and errors that you have to resolve in live during your exam.
Start by the HARD one
My strategy to get 3x Certificate in one month.
CKA: To get this one, you’ll need to understand the architecture, setup and backup the cluster, storage, network, security (RBAC, network policies) and resource deployment’s life cycle.
CKS: in any case, you can’t get this certificate without validating the previous one, then the next step would to be learn all about securing kernel (Apparmor, Seccomp…), Docker images (CSIBench, Trivy…) , mTLS, and Kubernetes security plugins like (PodSecurityPolicy, OPA, ImagePolicyWebhook, Audit Policy…).
CKAD: If you’ve got already the previous couple ones, you don’t have to learn more things to get the third, just get more familiar with life cycle, resource, and application deployment.
Learn planning
CKA: 20 days
CKS: 10 days
CKAD: 2 practice days
