Blazer on Ubuntu 24.04 LTS
Azure
Analytics
Blazer, the self hosted SQL business intelligence tool, bundled with a sample database and example dashboards so you can explore data and build charts the moment it boots.
Overview
Blazer is an open source business intelligence tool that lets you explore your data with SQL, turn queries into charts and dashboards, and set up data checks that alert you when something looks wrong. Analysts and engineers use it to answer questions directly against a database, share saved queries with the team, and assemble lightweight dashboards without a heavy BI platform.
This image bundles Blazer together with its own local PostgreSQL database, seeded with a sample dataset and a set of example queries, a dashboard and a data check, so it is a complete, self contained analytics workbench on first boot rather than an empty console that still needs a database wired up. It suits data exploration, internal reporting, evaluation and demos, and teams that want fast SQL charts behind a single secure login.
Why the cloudimg image
cloudimg delivers Blazer and its bundled PostgreSQL fully installed behind an nginx reverse proxy, so a populated console answers the moment the instance boots. The image is secure by default and carries no usable login: Blazer has no built in authentication, so cloudimg puts it behind an HTTP login and, on the first boot of every instance, a one shot service generates a random admin password, a fresh application secret and a fresh database password unique to that instance and writes the login to a file only the root user can read. The database listens only on loopback so it is never exposed to the network, the base is fully patched with unattended security upgrades enabled, and every deployment is paired with a step by step deploy guide and backed by 24/7 cloudimg support.
