Helm Drills

15 drills for Helm chart management muscle memory. Each takes 1-3 minutes.

Difficulty: [E] Easy (recall) | [I] Intermediate (combine flags/tools) | [H] Hard (multi-step debugging)

Remember: The Helm debugging workflow: helm list (what is deployed), helm status <release> (current state), helm history <release> (revision history), helm get values <release> (active config), helm rollback <release> <rev> (undo). Mnemonic: "LSHGR" — List, Status, History, Get, Rollback.

Gotcha: helm get values shows only user-supplied overrides by default. To see ALL effective values (defaults + overrides merged), use helm get values <release> -a. This is critical for debugging: the value you think is set might be overridden by a chart default.
