+## Docker Deployment
+
+The root `Dockerfile` builds the SvelteKit Node server with pnpm and runs it with `node build`.
+
+Build locally:
+
+```sh
+docker build \
+  --build-arg PUBLIC_CONVEX_URL=https://your-production-deployment.convex.cloud \
+  --build-arg PUBLIC_CONVEX_SITE_URL=https://your-production-deployment.convex.site \
+  -t journaley .
+```
+
+Run locally:
+
+```sh
+docker run --rm -p 3000:3000 \
+  -e PUBLIC_CONVEX_URL=https://your-production-deployment.convex.cloud \
+  -e PUBLIC_CONVEX_SITE_URL=https://your-production-deployment.convex.site \
+  -e HOST=0.0.0.0 \
+  -e PORT=3000 \
+  journaley
+```
+
+For Dokploy, choose a Dockerfile deployment, keep the Dockerfile path as `Dockerfile`, expose container port `3000`, and set the same environment variables in the Dokploy app settings. The public Convex URLs are also defined as Docker build args because SvelteKit's public static env values are compiled into the app during the image build.

 ## Auth
 
 This project uses Convex Auth with email/password for local development. The initializer created `convex/auth.config.ts`, `convex/auth.ts`, and `convex/http.ts`; the frontend uses `@mmailaender/convex-auth-svelte` for SvelteKit auth state and auth routes.
