Build Caddy with the caddy-dns/njalla plugin to enable DNS-01 ACME
challenges. This issues a single wildcard certificate for
*.sigkill.computer instead of per-subdomain certificates, reducing
Let's Encrypt API calls and certificate management overhead.
Add ddns-updater service (nixpkgs services.ddns-updater) configured
with Njalla provider to automatically update DNS records when the
server's public IP changes.
Generate and encrypt a Bearer token for llama-cpp's built-in auth.
Remove caddy_auth from the vhost since basic auth blocks Bearer-only
clients. Internal sidecars (xmrig-pause, annotations) connect
directly to localhost and are unaffected (/slots is public).
- coturn: switch static-auth-secret to static-auth-secret-file
- matrix: switch registration_token and turn_secret to file-based
- murmur: switch password to environmentFile with agenix
- p2pool: move public wallet address to service-configs.nix
