Knowage - Open Source Business Intelligence and Analytics

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

Overview

Knowage is a full open source business intelligence and analytics suite. It delivers interactive dashboards (cockpits), pixel-perfect reports, self-service data exploration, charts and data federation across multiple data sources, all from a single self-hosted Java web application. Model your data once and let business users explore it through the Knowage workspace, publish cockpits and share analytical documents across your organisation. This image delivers Knowage fully installed and configured as a production application, so you have a complete analytics platform running within minutes of launch, with full ownership of your data.

Why This Image Over DIY or Other Images

Unlike a manual install or a generic community image, this image ships production-hardened from the start. The application server and metadata database bind to loopback behind nginx with a per-instance self-signed TLS certificate, so the web interface is never exposed over plain HTTP or with a default login. Systemd manages Tomcat, PostgreSQL and nginx, restarting them on failure. A secure first-boot process generates a unique administrator password and a unique metadata-database password per instance and removes every well-known default account that Knowage ships, so there are no shared or default passwords to rotate. And 24/7 cloudimg support means you have engineers available for deployment, tuning and troubleshooting, something unsupported community images cannot offer.

Application Stack

• Knowage Server deployed on Apache Tomcat with the OpenJDK 17 runtime behind nginx on port 443 with TLS
• PostgreSQL as the metadata database on loopback only, on a dedicated data volume
• Systemd service management with automatic restart on failure
• Secure first-boot credential generation unique to each instance

Business Intelligence and Analytics

Knowage gives your teams interactive cockpits, self-service data exploration, charts, pixel-perfect reports and KPI monitoring over your own data. Connect multiple databases and datasets, blend and federate them, and let analysts build and share analytical documents through the Knowage workspace. Model data once and publish dashboards across the organisation, all from a self-hosted server in your own VPC.

Secure First Boot

On the first boot a one-shot service generates fresh per-instance encryption secrets, a fresh metadata-database password and a fresh administrator password, before the public web interface is started. Every well-known default account that Knowage ships is rotated or removed so none of them work. The administrator password is written to a file only the root user can read. No shared or default credentials ship in the image.

Ready To Use

The Knowage web interface is served on port 443 through nginx with a per-instance TLS certificate. Sign in with the generated administrator credentials to build datasets, cockpits and reports, connect your data sources and invite your team.
