kevinveenbirkenbachandClaude Opus 5 7bc12e55f3 fix(docs): drop the generated sections the designer merge put back
aceb5295ef moved Cosmos, Quick Setup and Credits out of the committed role
READMEs and into the documentation build's own scratch checkout, so a
committed copy can no longer go stale when the metadata moves. Merging
feature/designer (ebad39422c) took origin/main's side of those files, which
still carries them, and reinstated all 290 along with the cosmos make target
and its i8cos alias. tests/lint/ansible/roles/test_readme.py hard-fails on a
committed copy, and the reinstated Credits block credited one person with two
URLs, which tripped the credits-attribution lint as well.

Stripped with the repository's own fence-aware parser against
MANAGED_SECTIONS, not with a line filter: the Cosmos block holds a mermaid
fence a naive filter would cut through. The result is byte-identical to
aceb5295ef for every README that carries no prose change since.

The cosmos target wrote the forbidden section straight back into the
checkout, so it goes with them.

Docker Container Health Check

Description

This role monitors the health status of Docker containers on the system. It detects containers that are either unhealthy or have exited with a non-zero code, and triggers alerts if issues are found.

Overview

The role installs a health check script along with a systemd service and timer to run these checks at scheduled intervals.
If unhealthy or failed containers are detected, the configured failure notifier (via sys-ctl-alm-compose) is triggered.

Purpose

The primary purpose of this role is to ensure that Docker-based services remain operational. By automatically monitoring container health, it enables administrators to react quickly to failures, reducing downtime and preventing unnoticed service degradation.

Features

  • Automated Health Checks: Detects containers in unhealthy state or exited with non-zero exit codes.
  • Systemd Integration: Installs a one-shot service and timer to run health checks on a schedule.
  • Alerting Support: Works with the sys-ctl-alm-compose role for failure notifications.
  • Configurable Script Location: Controlled via the PATH_ADMINISTRATOR_SCRIPTS variable.
