Summary
AI summaryConfigurable upstream timeout raises default to 120s and clarifies write‑timeout ambiguity.
Full changelog
2.43.3 — Targets Portainer 2.43.x
Added
- Configurable upstream timeout (
PORTAINER_TIMEOUT, seconds) — #80. The
upstream Portainer HTTP timeout was hardcoded at 30s, routinely too short for
stack creation (Portainer deploys synchronously — the request holds open
through image pull and compose up). The default rises to 120s, the
connect phase stays capped at 10s so an unreachable Portainer still
fails fast, and the knob applies to both transports. Non-numeric or
non-positive values refuse to boot; the resolved posture is logged at
startup.
Changed
- Post-send timeouts now say the write may have succeeded (#80). A
request that times out after reaching Portainer is ambiguous, not failed
— Portainer keeps processing, which is how two timed-out stack creates
left two stack records behind in #80. FastMCP's stock error ("please
retry") invites exactly the duplicate-creating reflex, so
ReadTimeout/WriteTimeouterrors are rewritten to name the ambiguity,
instruct the model to verify current state (e.g.StackList) before
retrying, and point atPORTAINER_TIMEOUT. Connect-phase timeouts are
left untouched — the request never reached Portainer.
