The container's health-checker runs against Caddy via /etc/hosts resolution. The node:20-alpine base image has no entries for *.sami, so without explicit --add-host flags every *.sami probe resolves via the configured DNS server (100.121.150.22 Technitium or 8.8.8.8) — both of which DO resolve *.sami but return the WAN/Tailscale IP. That works for most services because Caddy on DNS2:443 handles them. BUT: a previous container run passed --add-host=git.sami:100.81.59.99 (DNS3's Tailscale IP). DNS3 does NOT serve HTTPS on 443 — Gitea listens on :3030 only. So git.sami health checks inside the container hit DNS3:443, get ECONNREFUSED, and the dashboard shows git.sami as down even though Caddy on DNS2:443 correctly routes git.sami → 100.81.59.99:3030. Fix: inject the correct --add-host flags from start.sh (the source of truth for container setup) so future recreates get consistent resolution. git.sami is intentionally left OUT — Caddy on DNS2:443 is the only correct ingress for git.sami traffic. Also documents the rationale so the next person doesn't reintroduce the git.sami override by accident. Live verified: - container /etc/hosts has all needed entries except git.sami - curl https://git.sami/ from inside container → 200 (via Caddy on :443) - curl https://sync.sami/ from inside container → 302 (upstream redirect) - curl https://router.sami/ from inside container → 302 (upstream redirect)

# --- /etc/hosts overrides for the container ---------------------------------
|
|
# The base image (node:20-alpine) has no entries for *.sami. We must inject
|
|
# them via --add-host so health checks inside the container can resolve LAN
|
|
# and Tailscale IPs to the right destinations.
|
|
#
|
|
# IMPORTANT: Do NOT add `git.sami:100.81.59.99` (DNS3). DNS3 does not serve
|
|
# HTTPS on 443 — it only serves Gitea on :3030. Setting git.sami → DNS3 in
|
|
# the container would make health checks bypass Caddy and hit a closed port.
|
|
# Let Caddy (on DNS2:443) handle git.sami and route to DNS3:3030 internally.
|
|
#
|
|
# Layout:
|
|
# dns3.sami / gitea → DNS3 (Tailscale IP, used by tools inside the container
|
|
# that need to talk to Gitea directly, e.g. backups)
|
|
# dns3-wan.sami → DNS3 Contabo WAN fallback
|
|
# dns2.sami → DNS2 (this host) — for cross-service references
|
|
# dns1.sami → DNS1 (SAMI-CLOUD-U32)
|
|
# dc-contabo-de → DashCaddy Contabo test instance
|
|
# git.dashcaddy.net → DashCaddy upstream git
|
|
# ca.sami → local CA (DN2 + DN3 both have their own)
