Open-source Platform for learning kubernetes and aws eks and preparation for for Certified Kubernetes exams (CKA ,CKS , CKAD)
Welcome to the SRE Learning Platform!
The SRE Learning Platform is an open-source hub designed to help IT engineers effectively prepare for the CKA (Certified Kubernetes Administrator), CKS (Certified Kubernetes Security Specialist), and CKAD (Certified Kubernetes Application Developer) exams. Additionally, this platform offers invaluable hands-on experience with AWS EKS (Elastic Kubernetes Service), equipping users with practical insights for real-world applications. Whether you're aiming to validate your skills, boost your career prospects in Kubernetes administration, security, application development, or delve into AWS EKS, this platform provides hands-on labs, practice tests, and expert guidance to ensure certification success.
- Prepare for the CKA: Certified Kubernetes Administrator Exam
- Enhance your skills for the CKS: Certified Kubernetes Security Specialist Exam
- Excel in the CKAD: Certified Kubernetes Application Developer Exam
Master Kubernetes concepts, gain practical experience, and excel in the CKA, CKS, and CKAD exams with the SRE Learning Platform.

About CKA, CKS, CKAD scenarios
- the platform uses aws to create following resources : vpc, subnets, security groups, ec2 (spot ), s3
- after you launch the scenarios the platform will create all the necessary resources and give access to k8s clusters.
- to create clusters the platform uses kubeadm
- you can easily add your own scenario using the already existing terraform module k8s_self_managment
- k8s_self_managment module supports versions:
k8s version : [ 1.21 , 1.29 ] https://kubernetes.io/releases/
Rintime :
docker [1.21 , 1.23]
cri-o [1.21 , 1.29]
containerd [1.21 , 1.29] # cks, cka default 1.29
containerd_gvizor [1.21 , 1.29]
OS for nodes :
ubuntu : 20.04 LTS , 22.04 LTS # cks default 20.04 LTS
CNI : calico
