What Changed # Pinned Graylog’s JVM heap to 1GB by adding explicit GRAYLOG_SERVER_JAVA_OPTS to docker-compose.yml:
1 GRAYLOG_SERVER_JAVA_OPTS: "-Xms1g -Xmx1g -XX:NewRatio=1 -server -XX:+UseG1GC" Why # Noticed high memory usage on the Graylog VM. JVM ergonomics was auto-allocating ~2GB for Graylog, leaving insufficient RAM for OS filesystem cache. OpenSearch query performance suffers without cache headroom.
What Changed # Upgraded Watchtower notifications from plain text to Discord embeds using Shoutrrr URL parameters:
Added colored sidebar (green for updates) Suppressed noisy startup messages Cleaner, more readable notifications Why # Plain text Watchtower notifications were hard to scan in busy Discord channels. Embeds provide visual structure and color-coding.
What Changed # Added Ansible playbooks to Semaphore for automated Proxmox cluster power management:
Night Sleep: Gracefully shuts down non-essential VMs/LXCs at night Day On: Wakes up the cluster in the morning Scheduled via Semaphore cron Why # Running all VMs 24/7 wastes power when they’re not needed. Automated scheduling reduces energy costs and wear on hardware.
What Changed # Renamed the main infrastructure repository from homelab-infrastructure to homelab-infra for brevity.
Why # Shorter name is easier to type and fits better in paths, prompts, and documentation. The word “infrastructure” was unnecessarily long.
Details # Renamed on GitHub Updated local clone Updated all cross-references in: CLAUDE.md files n8n-workflows documentation claude-config skill references Portainer Git stack URLs Result # All references updated. Portainer stacks continue to deploy correctly from new repo URL.
What Changed # Added three Ansible playbooks to Semaphore for managing Caddy reverse proxy domains:
Add Domain: Creates new reverse proxy entry on both HA nodes Remove Domain: Removes domain from both nodes List Domains: Shows all configured domains across the cluster Why # Manual Caddy config edits were error-prone and required SSH to both nodes. Semaphore templates provide a UI for common operations with built-in validation.
