Oasis Python UI

A web-based UI utilising Streamlit to manage exposure data and run modeling workflows on the OasisLMF platform.

The current version of the UI contains the following pages:

• /analyses - View and create portfolios and analyses.
• /dashboard - View the output of completed analyses.
• /simplified - Simplified UI which allows for the running of analyses using previously loaded portfolios & models.

Prerequisites

• git
• docker with Compose v2 (docker compose)

Quick Start

1. Choose an authentication type

Three modes are supported. Copy the matching environment template:

cp .env.simple .env # No OIDC — username/password login
cp .env.keycloak .env # Keycloak OIDC
cp .env.authentik .env # Authentik OIDC

Edit .env to adjust the hostname, passwords, or image versions if needed.

2. Configure .streamlit/secrets.toml

This file tells the UI how to authenticate against the Oasis API backend. Edit .streamlit/secrets.toml before running the installer — it is mounted read-only into the UI container.

Simple auth:

auth_type = 'simple'user = 'admin'password = 'password'

Keycloak or Authentik OIDC:

auth_type = 'oidc'client_id = 'oasis-service'client_secret = 'serviceNotSoSecret'

3. Add the hostname to /etc/hosts

The default hostname is ui.oasis.local. Add it to your hosts file so your browser can resolve it:

echo"127.0.0.1 ui.oasis.local"| sudo tee -a /etc/hosts

4. Run the installer

./install.sh

The installer clones the PiWind demo model, processes OIDC templates (if applicable), builds the UI image, and starts all services. It will prompt before redeploying if a previous installation is detected.

To tear everything down (removes containers and volumes):

./install.sh --uninstall

Access Points

All services are reachable on port 80 via Traefik after a successful install:

Service	URL
UI	http://ui.oasis.local/
API	http://ui.oasis.local/api/
Keycloak Admin	http://ui.oasis.local/auth/
Authentik Admin	http://ui.oasis.local/authentik/

Switching Between Auth Types

1. Bring down the current stack:

   ./install --uninstall

2. Copy the new .env template and edit if needed:

   cp .env.keycloak .env

3. Update .streamlit/secrets.toml to match if required (see step 2 of Quick Start).
4. Re-run the installer:

   ./install.sh

Docker Compose Architecture

The stack is assembled from multiple Compose files depending on auth type:

Always loaded:
docker-compose.yml # Core platform: server, worker, databases, broker
docker-compose.ui.yml # Streamlit UI + Traefik reverse proxy
Conditionally loaded:
docker-compose.keycloak.yml # Keycloak + its PostgreSQL DB (API_AUTH_TYPE=keycloak)
docker-compose.authentik.yml # Authentik + its PostgreSQL DB (API_AUTH_TYPE=authentik)

install.sh builds the correct docker compose -f ... up command automatically.

Key Environment Variables

Variable	Description	Example
API_AUTH_TYPE	Auth mode: simple, keycloak, or authentik	authentik
OASIS_UI_HOSTNAME	Hostname the UI and proxy listen on	ui.oasis.local
OASIS_PROTOCOL	http or https	http
VERS_API	Oasis server image tag	2.5
VERS_WORKER	Oasis worker image tag	2.5
VERS_UI	Python UI image tag	latest

See the .env.* templates for the full list with inline comments.

Adding Users

Simple auth

The default admin user (admin / password) is created automatically. Additional users must be added via the Oasis API or admin interface.

Keycloak

Edit oidc/keycloak/users.yaml and re-run ./install.sh, or add users through the Keycloak admin console at /auth/ (keycloak / password).

Authentik

Edit oidc/authentik/users.yaml and re-run ./install.sh, or add users through the Authentik admin console at /authentik/ (akadmin / password).

Troubleshooting

Usually first thing to try before anything is clearing browser cache/cookies for the hostname.

OIDC login redirects to the wrong URL

• Confirm OASIS_UI_HOSTNAME in .env matches the hostname you use in the browser.
• Confirm the same hostname resolves locally (check /etc/hosts).

UI cannot reach the API

• Verify Traefik is running: docker compose ps traefik.
• Check that the server container is healthy: docker compose ps server.
• Inspect Traefik routing logs: docker compose logs traefik.

Keycloak / Authentik container unhealthy

• Check logs: docker compose logs keycloak or docker compose logs authentik-server.
• The IdP database container must be healthy first: docker compose ps.
• First startup can take 2–3 minutes while blueprints and realms are imported.

Logs and status

docker compose ps # service health
docker compose logs -f <container_name># UI logs

Security Notes

• The .env templates and users.yaml files ship with demo credentials. Change all passwords before any non-local deployment.
