WebUI Connection Info
Dev Server Address
The WebUI dev server runs under Portless on a *.localhost:1355 URL.
scripts/dev.mjs picks the subdomain from the current git branch:
- Branch contains an
FR-XXXX token → http://fr-XXXX.localhost:1355 (e.g. 04-24-feat_fr-2701_... → fr-2701.localhost).
- Otherwise →
<branch>.<project>.localhost:1355 (Portless's default run form).
To find the actual URL for a running instance, run portless list or check the pnpm run dev terminal output.
If no dev server is running, tell the user to start it with pnpm run dev (requires Portless: npm install -g portless).
API Endpoint & Credentials
Read e2e/envs/.env.playwright to get the current server endpoint and login credentials.
Key variables:
E2E_WEBSERVER_ENDPOINT — Backend.AI API server URLE2E_ADMIN_EMAIL / E2E_ADMIN_PASSWORD — admin accountE2E_USER_EMAIL / E2E_USER_PASSWORD — regular user account- Additional:
E2E_USER2_*, E2E_MONITOR_*, E2E_DOMAIN_ADMIN_*
Always read the file fresh — credentials and endpoints change. Do not hardcode or cache them.
Login Flow
The WebUI login page requires:
- Email/Username
- Password
- Endpoint (may be hidden under "Advanced" toggle)
The app uses config.toml with connectionMode = "SESSION". If apiEndpoint is empty, the user must enter the endpoint manually on the login page.
Gotchas
- The
.env.playwright file may have multiple endpoints commented out (e.g., LTS vs main). Use the uncommented E2E_WEBSERVER_ENDPOINT.
- Passwords may contain special characters — handle quoting carefully.
- The webpack-dev-server overlay can intercept clicks. Remove it via:
document.getElementById('webpack-dev-server-client-overlay')?.remove()
- If the "Endpoint" input field is not visible on the login page, click "Advanced" to expand it.
