Certification Discount Codes That Actually Work
Updated August 2026 · Two official partner codes, one page
Right now there's a Linux Foundation sale running that beats RUSHABH30 (35% off with AUG26F35, 40% off bundles with AUG26F40, ends August 28). Details on the Linux Foundation page.
I hold two training partnerships, and they cover completely different catalogs on completely different checkouts. That trips people up, so this page exists to answer one question: which code do you need? Once you know, the linked page has the pricing, the exam formats, and the prep advice.
Which code do you need?
| If you're buying | Use | You save | Where |
|---|---|---|---|
| Any Linux Foundation or CNCF certification, course or bundle: CKA, CKAD, CKS, KCNA, KCSA, LFCS, LFCA, PCA, OTCA, ICA, CCA, CGOA, CAPA, Kubestronaut | RUSHABH30 |
30% | training.linuxfoundation.org |
| A FinOps Foundation certification: Practitioner, Engineer, FOCUS Analyst, AI Value, Technology Value | RUSHABH_20 |
20% | learn.finops.org |
They are not interchangeable. Each checkout rejects the other's code, which is the single most common thing people email me about.
Linux Foundation & CNCF: 30% off with RUSHABH30
This is the big catalog: every Kubernetes certification, the CNCF associate exams, LFCS and LFCA, the self-paced courses, and the Kubestronaut and Golden Kubestronaut bundles. The code is evergreen with no expiry, and it works on course + exam bundles as well as bare exams, which is usually the better buy. The cheapest way in is KCNA at about $175.

FinOps Foundation: 20% off with RUSHABH_20
A separate programme covering five self-paced FinOps certifications. Worth knowing up front: this code covers those five specifically and not FinOps Certified Professional, the multi-certification bundles, exam-only purchases, or corporate subscriptions. The cheapest is the FinOps Certified FOCUS Analyst at about $320.
All five certifications, what the code excludes, and which to take first →
Not sure which certification, never mind which code?
The short version of advice I give at meetups:
- You run Kubernetes in production. CKA. It's the one hiring managers actually check for, and it's a live-terminal exam so it proves you can do the job rather than describe it.
- You ship apps onto Kubernetes but don't run the cluster. CKAD.
- You're new to cloud native. KCNA for the vocabulary, or LFCA if you're starting further back than that.
- Your job is cloud cost. FinOps Certified Practitioner, which is the one that gives you and your finance team a shared language.
- You build cost data pipelines. FinOps Certified FOCUS Analyst, the cheapest entry point of the five.
When a sale beats both codes
A few times a year the Linux Foundation runs an official sale deeper than 30%, and sale codes never stack with partner codes. The rule is simple: use the single biggest discount available right now, even when that isn't mine. Both organisations give me advance notice of these, which is what the box below is for.
