Hey folks! The iximiuz Labs community and I have been preparing hands-on problems to practice Kubernetes with realistic scenarios, but in a controlled environment. Some problems will come in handy for CKA/CKAD/CKS preparation, others will challenge your knowledge of Kubernetes internals or make you debug rather advanced cluster issues, and of course, there are beginner-friendly problems, too.

It is a shameless self-promotion, but the absolute majority of the problems are free, and the playgrounds are also free to use for up to an hour a day. Plus, solving a challenge bumps up the daily free limit by 5 minutes, so you can easily double it by solving a dozen ;)
