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.

RUSHABH30 RUSHABH_20

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 buyingUseYou saveWhere
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.

Frequently asked questions

Which discount code do I need?
RUSHABH30 for anything on training.linuxfoundation.org, RUSHABH_20 for the five FinOps certifications on learn.finops.org. Each checkout rejects the other's code.
Are these real partner codes, or scraped coupons?
Both were issued to me directly by the organisations running the certifications, as an affiliate or promotional partner. Neither is recycled from an aggregator, and both are honoured at the official checkout.
Do they expire?
Neither has an end date. These pages rebuild daily, so if a code stops being honoured it gets corrected here rather than left up as a dead coupon.
What if a bigger sale is running?
Take the sale. The codes never stack with official sales, so always use the single biggest discount available at that moment. When one is live it's shown at the top of the relevant page here.
Why should I trust this over a coupon aggregator?
You don't have to take my word for it. I'm a named person with a checkable track record (Docker Captain, Grafana Champion, a public GitHub history), every price here is checkable against the official catalog, and I tell you when a sale beats my own code rather than hiding it.
