Learn Kubernetes & Vault
Three free platforms I build and maintain to fill the gap in French-language Cloud Native certification prep — gamified, multilingual and open access.
Pick your platform
All are 100% free, open access, multilingual, and actively maintained. No credit-card registration, no ads.
KubeDex
kubedex-app.vercel.app
Gamified platform to learn Docker & Kubernetes step by step — 5 worlds, 40+ lessons, built-in CLI/YAML editor, badges & XP.
VaultQuest
vaultquest-five.vercel.app
Learn HashiCorp Vault and prep for the Vault Associate (003) certification — theory, hands-on labs and mock exams aligned with the official curriculum.
CKA-Quest
cka-quest-app.vercel.app
Prepare the Certified Kubernetes Administrator (CKA) in French, English and several other languages — mock questions, practice environments, detailed scoring.
Why free?
Filling a real gap
Almost every Cloud Native cert prep tool is English-only. Many French-speaking learners hit the language barrier before they even hit the technical one.
Learn by doing
No passive PDFs: built-in CLI/YAML editors, interactive lab environments, detailed scoring on questions modeled on the real exams.
Open access, no card
No credit-card signup, no hidden subscription, no ads. Open the URL, start learning. Real knowledge-sharing.
Actively maintained
Regular updates aligned with new Kubernetes & Vault releases. Public GitHub issues, community feedback integrated.

Frequently asked
Will the platforms stay free?
Yes. The model is and will remain open-access. It’s a knowledge-sharing initiative, not a commercial product. Maintenance is funded by my consulting activity.
Which certifications are they aligned with?
VaultQuest targets Vault Associate (003). CKA-Quest targets the Certified Kubernetes Administrator (CKA). KubeDex is general-purpose and covers Docker + Kubernetes + OpenShift — ideal as a primer before a certification.
Can I contribute?
Yes. Feedback, ambiguous-question reports and new-lesson proposals are welcome through the public GitHub issues (linked from each platform).
How are they kept up to date?
On each major Kubernetes or Vault release I revise the impacted lessons and questions. The public roadmap above lists the next milestones.
Do you offer corporate training?
Yes, on request. I design tailored Kubernetes / OpenShift / Vault training programs for teams — from onboarding to certification prep. Reach out via the Contact page.
