Getting Started

Prerequisites

• .NET 9 SDK
• Node.js 20+
• Docker Desktop

1. Start infrastructure

cp .env.example .env
# Edit .env and set a strong POSTGRES_PASSWORD
docker compose up -d

2. Configure backend

cp backend/SentinelOps.API/appsettings.json backend/SentinelOps.API/appsettings.Development.json
# Edit appsettings.Development.json — set DB password, JWT key, and OpenAI API key

Run migrations:

cd backend
dotnet ef database update --project SentinelOps.Infrastructure --startup-project SentinelOps.API

Start the API:

dotnet run --project SentinelOps.API
# Runs on http://localhost:5076

3. Start frontend

cd frontend/sentinelops-ui
npm install
npm start
# Runs on http://localhost:4200
