About Hosting TrendRadar

TrendRadar collects topic signals on a cron schedule, stores generated SQLite and HTML report files, and exposes the report over HTTP. The template runs the official Docker image with an application ConfigMap and a persistent /app/output volume.

Local storage is the default backend. To use S3-compatible storage, set Storage Backend to remote and fill the S3 endpoint, bucket, access key, secret key, and region fields.

Common Use Cases

Trend monitoring: Track topics such as AI, cloud, startups, and product launches.
Scheduled reports: Generate fresh HTML reports on a cron schedule.
Newsletter research: Collect high-signal items for editorial review.
Lightweight intelligence dashboard: Serve generated reports from a stable HTTPS URL.

Dependencies for TrendRadar Hosting

The Sealos template includes the TrendRadar container, configuration files, local persistent storage, public HTTPS ingress, and optional S3-compatible storage inputs.
