RH134 — Declarative management and system convergence
Introduction to declarative administration, runtime management, and convergence tools (ch04s04).
Goal
Capture RH134 v10.0 — section 4.4 (course page on ROL) while working through it: understand converging the system to a desired state instead of only running ad‑hoc commands.
What this exercise introduces
- System automation — reliable, repeatable, auditable tasks.
- Declarative administration — describe how the system should look, not only which command to run next.
- Runtime management — what is running now, how it is monitored and recovered.
- Persistent system configuration — changes that survive reboots and redeployments.
- Convergence tools — the system moves toward the target until configuration and services align.

| Area | Example |
|---|---|
| Culture and delivery | DevOps, CI/CD |
| Infrastructure | Infrastructure as Code |
| Orchestration | Kubernetes, OpenShift |
| Initial provisioning | cloud-init |
| Host automation | Ansible |
For RHCSA the focus stays on Linux on the host; this chapter bridges daily sysadmin work with the wider ecosystem.
