OIDC is pansy's primary login path (Authentik the target IdP); local auth (#4) remains the fallback and both issue the same session cookie. - deps: github.com/coreos/go-oidc/v3 + golang.org/x/oauth2 (both pure Go; CGO stays off). - api/oidc.go: lazy issuer discovery (retried per-request, never crashes a server that also serves local auth), GET /auth/oidc/login builds an authorization-code URL with PKCE S256 + random state + nonce stashed in a short-lived HttpOnly cookie, GET /auth/oidc/callback verifies state (constant-time), exchanges the code with the PKCE verifier, verifies the ID token + nonce, and starts a pansy session. Failures redirect to /login?error=... ; success to /gardens. - service.LoginOIDC: (issuer,subject) match -> login; else *verified* email match -> link onto the existing account; else JIT-create (the IdP gates access, so PANSY_REGISTRATION doesn't apply). Unverified email colliding with an existing account is refused (takeover guard); no email is refused (email is the account key). Reuses the atomic CreateUser. - store: GetUserByOIDC + LinkOIDC (unique-pair backstop). - config: OIDCReady() (needs issuer+client+BaseURL for the redirect URI); /auth/providers now reports oidc from it and defaults the button label to "Sign in with Authentik". OIDC routes are only registered when ready, so an unconfigured instance 404s them. - PANSY_LOCAL_AUTH=false rejects/hides local auth but not OIDC. Tests: service provisioning (JIT, repeat login, link, unverified-collision refusal, no-email, name fallback, works with local auth off); api (routes-absent-when-unconfigured, providers reporting, login redirect with PKCE params + tx cookie via a fake discovery server, callback state/error paths). Smoke-tested: unreachable issuer degrades to error=oidc_unavailable with the server still up and local auth working.

pansy
Self-hostable garden planner: drag beds, bags, and containers onto a real-scale field, click into them to place freeform plops of plants, and zoom out to see what's planted where. Go backend + React frontend, one static binary.
See DESIGN.md for the architecture. Work is tracked in this repo's issues — start from the tracking epic.
Quickstart
Prerequisites: Go 1.26+, Node 20+.
Develop
Run the Go API and the Vite dev server together (Vite proxies /api → the API):
make dev
Then open http://localhost:5173. Or run the two halves in separate terminals for independent restarts:
make dev-api # Go API on :8080
make dev-web # Vite dev server on :5173
Build & run
Produce the single static binary with the web build embedded, then run it:
make build
./pansy
Open http://localhost:8080 — one process serves both the JSON API and the app.
Test
make test
Configuration
All configuration is via environment variables; every value has a default, so ./pansy runs with none set.
| Variable | Default | Description |
|---|---|---|
PANSY_PORT |
8080 |
TCP port the HTTP server listens on. |
PANSY_DB |
./pansy.db |
SQLite database file path (created if absent). |
PANSY_BASE_URL |
(empty) | Externally-visible base URL; used to derive the OIDC redirect URI. |
PANSY_REGISTRATION |
open |
open or closed — gates local self-service signup. |
PANSY_LOCAL_AUTH |
true |
Enable local password auth. Set false for pure-OIDC. |
PANSY_OIDC_ISSUER |
(empty) | OIDC issuer/discovery URL (Authentik). Enables SSO when set. |
PANSY_OIDC_CLIENT_ID |
(empty) | OIDC client ID. |
PANSY_OIDC_CLIENT_SECRET |
(empty) | OIDC client secret. |
PANSY_OIDC_BUTTON_LABEL |
Sign in with Authentik |
Label for the OIDC button on the login page. |
PANSY_TRUSTED_PROXIES |
(none) | Comma-separated proxy CIDRs/IPs to trust for client-IP resolution. |
Local email/password auth is live (POST /api/v1/auth/register, /auth/login, /auth/logout, GET /auth/me, GET /auth/providers); the session is an HttpOnly cookie (Secure when PANSY_BASE_URL is https). The first account registered becomes admin, and it may register even when PANSY_REGISTRATION=closed to bootstrap the instance.
OIDC (Authentik-first) is live too: set PANSY_OIDC_ISSUER, PANSY_OIDC_CLIENT_ID, PANSY_OIDC_CLIENT_SECRET, and PANSY_BASE_URL (needed for the redirect URI). Register PANSY_BASE_URL + /api/v1/auth/oidc/callback as the redirect URI in your IdP. GET /auth/oidc/login starts an authorization-code + PKCE flow; first login provisions a user just-in-time (a matching verified email links to an existing local account instead of duplicating it). Provider discovery is lazy, so a briefly-unreachable IdP never blocks startup or local auth. Set PANSY_LOCAL_AUTH=false for pure-Authentik deployments (local register/login are then rejected and hidden from /auth/providers).
Docker & deployment
CI (.gitea/workflows/build-image.yml) builds the single-binary image and pushes it to the Gitea registry on every branch push:
| Ref | Tag |
|---|---|
main |
gitea.stevedudenhoeffer.com/steve/pansy:latest |
| any other branch | gitea.stevedudenhoeffer.com/steve/pansy:<branch-name> |
| every build | gitea.stevedudenhoeffer.com/steve/pansy:sha-<short> (immutable; use to pin) |
The image runs as a non-root user, serves on :8080, and stores the SQLite database on the /data volume. Run it directly:
docker run -d --name pansy \
-p 8080:8080 \
-v pansy-data:/data \
gitea.stevedudenhoeffer.com/steve/pansy:latest
Or as a Komodo/Compose stack:
services:
pansy:
image: gitea.stevedudenhoeffer.com/steve/pansy:${PANSY_TAG:-latest}
ports:
- "8080:8080"
volumes:
- pansy-data:/data
environment:
PANSY_BASE_URL: https://pansy.example.com
# PANSY_OIDC_ISSUER: ... # once auth (#5) lands
restart: unless-stopped
volumes:
pansy-data:
Pin PANSY_TAG to a sha-<short> tag for reproducible deploys, or leave it at latest to track main.
