New site config key: CADDY_REMOTE_HOST (set via 'sudo ./setup.sh configure'). When set, configure_caddy_for_service operates in "remote" mode instead of writing to a local Caddyfile: - Upstream uses CADDY_REMOTE_HOST:PORT (host IP, not container name) - Snippet saved to ~/docker/caddy-snippets/<subdomain>.caddy - User is shown scp/rsync commands to copy it to the Caddy machine Three modes in configure_caddy_for_service (lib/common.sh and inline stubs): local: ~/docker/caddy/ exists → write Caddyfile + reload (existing behavior) remote: CADDY_REMOTE_HOST set → save snippet, print copy instructions none: neither configured → silent return (unchanged) All 31 service standalone bootstrap stubs updated with the new logic. CADDY_REMOTE_HOST global added to all 42 standalone bootstrap sections. setup.sh configure now prompts for CADDY_REMOTE_HOST with a clear explanation. wolf.sh: add missing stubs (configure_caddy_for_service, write_readme, prompt_yn, ensure_docker_dir_ownership) and the Authelia/Caddy/start calls that were missing from the install function. https://claude.ai/code/session_014CCYqVwW6d6f5dw1qRokYt

# services/backup.sh — Full Docker-service backup via Kopia.
|
|
# Part of the modular post-install system (sourced by setup.sh).
|
|
#
|
|
# Can also be run standalone on any machine:
|
|
# sudo bash backup.sh
|
|
# (Docker must already be installed when run standalone)
|
|
#
|
|
# Backs up each entire ~/docker/<service>/ directory (compose file, config, data,
|
|
# databases — everything needed to restore from nothing). Per-service behaviour:
|
|
# Minecraft instances — flush world to disk (save-all), snapshot, no downtime
|
|
# All other services — stop, snapshot, restart (seconds of downtime each)
|
|
#
|
|
# Different services can be routed to different Kopia repos / drives.
|
|
# New services are auto-discovered on every run — no reconfiguration needed.
|
|
#
|
|
# Creates: ~/docker/backup/
|
|
# backup.conf settings + per-service destination map (chmod 600)
|

# backup_kopia.sh worker (run directly or via systemd timer)
|

# restore_kopia.sh interactive restore helper
