Foundation

Cloud + Linux baseline before Kubernetes

3–4 weeks

CLF-C02AWS Cloud Practitioner

Kubernetes usually runs on cloud infrastructure. A cloud foundation prevents you from being blocked by unfamiliar IAM, VPC, or networking concepts when studying CKA.

FoundationLinux FoundationOptional
6–10 weeks

LFCSLinux Foundation Certified SysAdmin

Kubernetes runs on Linux. LFCS proves hands-on Linux administration skills (processes, networking, storage, systemd) that Kubernetes operators need daily.

CKSCertified Kubernetes Security Specialist

Cluster hardening, pod security, supply chain security, and runtime threat detection. Requires CKA as prerequisite. Increasingly required for security-sensitive Kubernetes roles.

Frequently asked questions

Do I need Docker experience before CKA?

Yes — you need to understand container images, layers, and basic Docker commands. Kubernetes abstracts away Docker at the runtime level but the mental model of containers (images, registries, resource limits) is assumed knowledge in the CKA exam.
