How to prepare for the CKA: labs, domains and voucher redemption

2026-08-12

Study path

1. Review the official exam domains (cluster architecture, workloads, networking, storage, troubleshooting).
2. Practise in a local cluster (kind / minikube) under time pressure.
3. Purchase the voucher on lfossa.org — the code appears in My Portal → Voucher library after payment.
4. Redeem at training.linuxfoundation.org.
