This document describes how to manage edge proxy and related services on the VPS.

Caddy (public reverse proxy)

Status

systemctl status caddy

Validate configuration

caddy validate --config /etc/caddy/Caddyfile

Apply changes

systemctl reload caddy

Logs

journalctl -u caddy -f
journalctl -u caddy -n 100 --no-pager

Backup Caddyfile

cp -a /etc/caddy/Caddyfile /root/backups/caddy/Caddyfile.$(date +%F)

MediaWiki stack

cd /var/www/wiki.jb
docker compose ps
docker compose logs -f wiki
docker compose restart wiki werbs-wiki

See Documentation:Wiki Deployment.

WebApp stack

See Webapp:Deployment.

OpenVPN

systemctl status openvpn-server@server
ip addr show tun0

Maintenance checklist

Confirm Caddy is active and config validates after hostname changes

Review journalctl -u caddy after incidents

Keep Docker images updated for wiki and WebApp stacks

Verify Let's Encrypt renewal (handled by Caddy; check logs if certificates near expiry)
