Config Script

Use idempotent scripts to enforce configuration state.

Intent

Turn configuration tasks into repeatable scripts that can run safely.

When to use

  • You need recurring compliance checks or setup tasks.
  • Manual configuration causes inconsistency.
  • You want a self-healing baseline.

Core mechanics

  • Check current state before changes.
  • Apply only missing settings.
  • Log every change and result.

Implementation checklist

  1. Define desired state and prerequisites.
  2. Implement checks for current state.
  3. Apply minimal changes with safe defaults.
  4. Log actions and outcomes.
  5. Add dry-run support or verbose mode.

Failure modes and mitigations

  • Scripts assume wrong state -> add checks and guards.
  • Partial updates -> make steps idempotent.
  • Permissions issues -> validate required privileges.

Observability and validation

  • Step-level status logs and change counts.
  • Compliance pass summary.

Artifacts

  • Configuration script and README.
  • Sample output logs.
  • Checklist of enforced settings.
