nn: serve Hugo over the tailscale IP when the host has one#986
Merged
Conversation
When a Hugo project is detected and the host has a tailscale IPv4, open Hugo's serve ports (1313-1316) so `hugo server --bind $TAILSCALE_IP` can bind+listen, export $TAILSCALE_IP, and append the IP to NO_PROXY so an in-sandbox client (curl, the Playwright MCP) reaches the served site directly instead of through the credential proxy. This lets the site be served to other tailnet devices and inspected from inside the sandbox. Hugo detection is factored out to the top of bin/nn so the grant follows the project even when a pre-generated .nono/profile.json or a --profile override skips the mixin auto-gen block. Gated on a tailscale IP existing so non-tailnet Hugo sandboxes keep the ports closed and NO_PROXY at loopback. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

bin/nnnow sets up the sandbox to serve the site over tailscale and inspect it:1313–1316) via--open-portsohugo server --bind $TAILSCALE_IPcan bind+listen (the default chain'sopen_portdoesn't cover 1313).$TAILSCALE_IPand prints a copy-pasteable serve command.NO_PROXYso an in-sandbox client (curl, the Playwright MCP) reaches the served site directly instead of through the credential proxy.Hugo detection is factored to the top of
bin/nnso the grant follows the project even when a pre-generated.nono/profile.jsonor a--profileoverride skips the mixin auto-gen block. Gated on a tailscale IP existing, so non-tailnet Hugo sandboxes keep the ports closed andNO_PROXYat loopback.Why
nono's network mediation is port-based, so serving on the tailscale IP just needs the serve port opened; the IP is what Hugo binds to. This lets the site be served to other tailnet devices and inspected from inside the sandbox.
