Kubernetes Gym: Jobs and CronJobs
Fast, repeatable kubectl exercises for the Job and CronJob lifecycle.
Small, fast kubectl exercises with one aim: building muscle memory for the Job and CronJob lifecycle.
Practice in a real terminal
Work in an ordinary shell on a real Linux VM. Shell Gym watches what you do and completes each rep automatically as soon as you reach the goal.
Small reps, focused gyms
Each module groups a handful of short reps around one command or concept, so you can focus on one thing at a time and build the skill step by step.
Spaced repetition, built in
The gym comes back after 1, 3, 7, 14, 30 days, so you revisit the commands before they fade and gradually turn deliberate practice into muscle memory.
Built into Daily Practice
When a gym is due, it appears in your Daily Practice. Pause it when you need a break, or complete it once the skill has become second nature.
Every session on record
Each session records how long you practiced and how many reps you completed, so you can see your training history and progress right here.
Help when you get stuck
Open a hint or follow the live feedback Shell Gym gives you based on what it sees on the VM — just enough to get unstuck without giving away the answer.
