About this template

Overview

TrendRadar tracks trending topics, generates scheduled reports, and serves the latest HTML report through a built-in web server. This template deploys TrendRadar with local persistent storage by default and optional S3-compatible remote storage.

From the documentation

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.

How to deploy TrendRadar

  1. Choose Deploy now to start TrendRadar in your Sealos workspace.
  2. Review enable_s3_storage, cron_schedule in the deployment form.
  3. Launch the template, then inspect the application status and resource cards in Canvas.

Resources to plan for

Start with the resources defined by the TrendRadar template. Review CPU, memory, persistent storage, and network allocations for every service in Canvas. Capacity needs depend on your data and workload; monitor usage as they grow.

Template configuration and setup

Access after deployment

Use the application URL or connection details shown in Canvas. Follow the deployment guide for first-time account setup or client configuration, and keep generated credentials available for that step.

Hosting and billing

Sealos monthly plans include compute, memory, storage, and traffic. Size your plan for all deployed services. Software licenses and external AI or API services may have separate terms and charges. Confirm the applicable plan and optional charges in Cost Center.

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.

Deployment Dependencies

Implementation Details

Architecture Components:

  • TrendRadar: Scheduler, crawler, report generator, and web server.
  • ConfigMap: Minimal config.yaml and frequency_words.txt mounted into /app/config.
  • Persistent Storage: /app/output stores generated local reports.
  • Optional S3 Storage: Remote S3-compatible storage through STORAGE_BACKEND=remote and S3_* environment variables.

Configuration:

  • cron_schedule controls report collection timing.
  • storage_backend accepts local or remote.
  • S3 fields are ordinary optional inputs; fill them when storage_backend is remote.

License Information:

TrendRadar is licensed under GPL-3.0.

Why Deploy TrendRadar on Sealos?

Sealos provides automatic HTTPS, persistent storage, and a simple deployment form for cron and storage settings. The template gives TrendRadar a stable public report URL with minimal operational setup.

Deployment Guide

  1. Open the TrendRadar template and click Deploy Now.
  2. Configure the parameters in the popup dialog. Use local storage for the built-in persistent volume, or choose remote and fill the S3 fields.
  3. Wait for deployment to complete, typically 2-3 minutes. After deployment, you will be redirected to the Canvas.
  4. Open the generated application URL to view the latest HTML report.

Configuration

Edit the ConfigMap from the Sealos Canvas to change topic groups, filters, and report behavior. Use the resource card to adjust CPU, memory, storage, and environment variables.

From launch to everyday operations

Why deploy
on Sealos

A shorter path from an app you want to an app you can run. Sealos brings deployment and ongoing operations into one place.

  1. One-click deployment

    Start with a ready-made template. Review its configuration and launch from the Sealos console.

  2. Managed Kubernetes

    Run on managed infrastructure with built-in workload scheduling and recovery.

  3. Automatic HTTPS

    Give your application a public HTTPS endpoint with certificates managed for you.

  4. Persistent storage

    Keep application data on persistent volumes across container restarts.

  5. Room to grow

    Adjust CPU, memory, and replicas from the console as your workload changes.

One template. Connected resources.

You Get the Whole Stack

Sealos provisions the resources defined by your template and brings them together in your workspace.

  • App Service

    Container workloads with configurable CPU, memory, and replicas.

  • Public HTTPS URL

    An address for your app, with managed TLS certificates.

  • Database

    A database provisioned alongside your app when the template calls for one.

  • Persistent Volume

    Storage for the files and data your application needs to keep.

  • Environment Variables

    Application settings and secrets configured in one place.

  • Logs & Metrics

    Inspect container logs and resource usage from the console.

Resources and their configuration vary by template. Review the deployment form for this app’s exact setup.
