An endpoint on podman's rootless default (pasta) has no address another
container can use, measured on 2026-10-19 from inside open-notebook:
- 192.168.0.143:7770 connection refused (pasta forwards the
published port in the host netns; no netavark
DNAT exists for traffic arriving from a
rootless bridge)
- host.containers.internal:7770 200, but the alias resolves to 169.254.1.2 —
link-local, which open-notebook's URL guard
refuses to store
- frank-dragoon-halogen:8731 name unknown: different netns
- --network pasta --network dankclaw_default
"cannot set multiple networks without bridge
network mode" — pasta cannot be added to
So reaching the NPU endpoints from an app container means moving the container
onto dankclaw_default (FRANK_DRAGOON_NETWORK; empty keeps today's shape). This
is not an exposure change: the engine's unauthenticated token port binds the
container's own loopback (/proc/net/tcp: 127.0.0.1:8730 against 0.0.0.0:8731),
so only the API port becomes name-resolvable — the same trust the published
7770 already carries on the LAN. The deployer refuses a network that does not
exist rather than starting a unit that restart-loops on it.
