Why it's worth it

Kubestronaut is CNCF's recognition for engineers who hold all five Kubernetes certifications — KCNA, KCSA, CKA, CKAD, and CKS — at the same time. Buying the bundle is the practical way to work toward it: on a five-exam purchase, RUSHABH30 produces the single biggest dollar saving it can generate, and this page runs the actual math instead of just quoting a percentage.

Prep tips

Sequence matters: CKS needs an active CKA, so plan CKA before CKS even if you buy all five exams in one bundle purchase.
KCNA and KCSA (both multiple choice) are the fastest wins — knock those out first for early momentum before the three performance-based exams.
Because each cert has its own validity window, think about scheduling cadence up front so you're not racing to renew an early cert before you've sat the later ones.

Frequently asked questions

What is Kubestronaut?

Kubestronaut is CNCF's official recognition for engineers who hold all five Kubernetes certifications — KCNA, KCSA, CKA, CKAD, and CKS — simultaneously.

How much does the Kubestronaut bundle cost with a discount code?

List price is $1645 for all five exams. With RUSHABH30 it drops to about $1151, a saving of roughly $494 — the largest single saving RUSHABH30 produces on any purchase.

Do I have to pass all five exams at once?

No — buying the bundle just locks in the discounted price for all five; you can schedule and sit each exam on your own timeline within your eligibility window.

Which exam should I take first in the bundle?

KCNA is the common starting point since it's multiple choice and builds vocabulary the other four assume you already know. Save CKS for last since it requires an active CKA.

Is there an even bigger bundle than Kubestronaut?

Yes — the Golden Kubestronaut bundle adds every other CNCF associate exam plus LFCS on top of the five Kubestronaut certs, for engineers going for the full catalog.
