Spring-AI ignores the showcase-wide OPENAI_BASE_URL because its split
base-url + completions-path model would produce a double-/v1 against
aimock. Introduce SPRING_AI_OPENAI_BASE_URL carrying the host without
/v1 (e.g. http://aimock:4010), default to https://api.openai.com.
Additionally, pin WebClient's JDK HttpClient to HTTP/1.1 and disable
connection pooling:
- Without reactor-netty, Spring-AI's auto-configured WebClient sent
`Upgrade: h2c` on every cleartext request, which some fixtures (aimock)
reject with 404.
- Default JDK HttpClient pooling reused half-closed sockets between
fixture responses, tripping `Connection reset` on tool-result follow-ups.
L3 chat now passes locally against the stack. L4 tool-rendering still
needs additional work (tool-execution loop cap WIP in BoundedToolCallingManagerConfig).
Wires up a single-command path to run the full integration smoke suite
against a local Docker stack instead of Railway. Useful when Railway is
degraded (OOM, rate limits) or when testing changes that haven't been
deployed yet.
Additions:
- showcase/docker-compose.local.yml: add `aimock` as 18th service so
integration containers can reach http://aimock:4010 on the compose
network, mirroring the Railway setup where they call showcase-aimock.
- showcase/tests/e2e/integration-smoke.spec.ts: `LOCAL_PORTS=1` env
rewrites each integration's Railway URL to http://localhost:<port>
via showcase/shared/local-ports.json. Starters are skipped under this
flag because they aren't in local-ports.json.
- showcase/scripts/smoke-local.sh: orchestrates build → up → wait → run
Playwright → tear down. Supports --level=L1/L2/L3/L4, --keep, --no-build.
- showcase/tests/package.json: `pnpm smoke:local[:L1|:keep|:nobuild]`
scripts delegate to the helper.
- showcase/.env.example: document optional OPENAI_BASE_URL +
ANTHROPIC_BASE_URL (route through local aimock) and package-specific
GitHubToken + GOOGLE_API_KEY (ms-agent-dotnet, google-adk).
Verified locally: `pnpm smoke:local:L1` → 17/17 L1 green against the
local stack.
Adds a single command to spin up the exact image Railway deploys,
for any of the 17 showcase packages, with a single shared .env:
./showcase/scripts/dev-local.sh up [<slug> ...] # all if empty
./showcase/scripts/dev-local.sh down|build|logs|ps|ports
Pieces:
- `docker-compose.local.yml` with a service per package. Ports come
from `shared/local-ports.json` (langgraph-python -> 3100, ...).
- `.env.example` as a commit-safe template. Real `.env` is gitignored
and fed to every container via `env_file`, so keys (OPENAI_API_KEY,
etc.) live in one place.
- `dev-local.sh` wraps `docker compose` and handles the
`shared_python/` / `shared_typescript/` staging step that CI does
before `docker build` (see showcase_deploy.yml).
- Staged `shared_*` dirs added to .gitignore.
Shell wiring:
- `shell/next.config.ts` reads `shared/local-ports.json` when
`SHOWCASE_LOCAL=1` is set and injects it as a public env.
- `/integrations/[slug]/[demo]/preview` uses that map to iframe
`http://localhost:<port>` instead of `integration.backend_url`.
Per-slug; any slug not running locally falls back to Railway.
Unset SHOWCASE_LOCAL -> prod behavior, unchanged.
Full workflow + prerequisites (Colima / Docker Desktop) documented in
showcase/README.md.
