Ops Reverse Proxy

Operator stack today: HTTP-only on the reverse proxy

Treat the edge (Traefik / Nginx / frp) as plain HTTP (port 80 or frp equivalent). Do not add TLS, websecure, tls=true, certresolver, or require Let’s Encrypt until existing projects on the same VPS clearly terminate HTTPS or the user explicitly asks for HTTPS.

Post-deploy check: curl -sS -I http:/// (and Host: if needed), not https:// by default.

Inspect first, then copy the pattern

Before writing a new docker-compose.yml, Traefik labels, or an Nginx server {}, understand what already runs on the target server and how other projects are wired. Otherwise you get a second incompatible stack (wrong Docker network, wrong entrypoint).

Remote VPS work uses vpshostssh:

ssh -F /data/.ssh/config vps 'COMMAND'

(If the bot runs without Docker but with HOST SHELL, the same SSH from the configured host is fine.)

Step 1 — what serves traffic (HTTP first)

1. Containers: docker ps --format 'table {{.Names}}\t{{.Image}}\t{{.Ports}}'
2. Traefik: names like traefik, proxy, image traefik:*. If present, sample labels from a routed service:

• docker inspect SERVICE_NAME --format '{{json .Config.Labels}}' | head -c 12000
• Check entrypoints: if everything is web / :80, new services stay HTTP-only. If you see websecure + tls.certresolver, copy TLS like the neighbors.

1. Host Nginx: test -d /etc/nginx/sites-enabled && ls -1 /etc/nginx/sites-enabled || true and optionally grep -R listen /etc/nginx/sites-enabled/ 2>/dev/null | head -30 — if only listen 80, do not add listen 443 ssl without a user request and certs.
2. frp: pgrep -a frpc || true; common paths ~/frp/frpc.toml, /etc/frp/frpc.toml, /opt/frp/frpc.toml — read-only. For HTTP prefer type = http and customDomains; do not switch to https without a clear need.

Step 2 — where other compose projects live

Avoid aggressive find /:

ssh -F /data/.ssh/config vps 'for d in /opt /srv /var/www /root /home/*/apps; do test -d "$d" && ls -la "$d" 2>/dev/null; done'
ssh -F /data/.ssh/config vps 'ls -d /opt/*/docker-compose.yml /srv/*/docker-compose.yml 2>/dev/null | head -20'

Open one closest neighbor and note:

• External Docker network name (traefik_public, web, proxy, …);
• Traefik: label prefix, entrypoints (HTTP vs HTTPS), certresolver if any;
• Nginx: server_name, listen, proxy_pass / upstream.

Step 3 — new service “like theirs”

• Traefik HTTP (default): same network as neighbors. Labels: enable=true, rule=Host(\sub.example.ru\), entrypoints=web (or whatever neighbors use on :80). No tls=true if neighbors on that entrypoint have no TLS.
• Traefik + TLS: only if neighbors already use websecure and the same tls.certresolver — copy those names.
• Nginx HTTP: new server { listen 80; server_name ...; location / { proxy_pass ... } } like the neighbor. Certbot / listen 443 only on explicit user request or if the whole host is already HTTPS.
• frp: same type and domain pattern as existing proxies; DNS (A) to frps if that is how neighbors work.

Step 4 — DNS alignment

REG.RU subdomain — skill opsdnsregru. A record points at the machine that actually receives HTTP (VPS or frps).

Do not

• Remove neighbor sites or shared Traefik without explicit user approval.
• Paste secret file contents or full neighbor configs in chat — only facts (network names, entrypoints, paths).
