BAC-L2-OPS-102
Configuration management
Provisioning a machine is not enough: it must be configured idempotently, so that ten nodes are genuinely identical.
- Level
- L2 — Appchain developer
- Duration
- 3 h
- Maintainer
- DevOps / Blockchain Infrastructure Engineer
Learning objectives
- 01Write an idempotent, replayable configuration
- 02Apply the same configuration across a fleet
- 03Verify a machine's conformance to its configuration
Guided lab
Configure three identical nodes and check conformance after deliberate drift.
Independent lab
Add configuration for a node of a different protocol without duplicating the shared base.
Security angle
Hardening applied through configuration — verifiable and replayable — rather than by hand.
Assessment
Automated conformance check passing across the whole fleet.
