## Apache Druid 37 on Ubuntu 24.04 LTS by cloudimg

Apache Druid is the open-source real-time analytics database built for fast slice-and-dice queries on event and time-series data at scale. It powers sub-second OLAP queries over streaming and batch ingestion through a column-oriented store, a built-in indexing service and a rich web console. The cloudimg image installs Apache Druid 37.0.0 on OpenJDK 17 as a single-server deployment, brings up the full coordinator, overlord, broker, historical, middle-manager and router stack under systemd, fronts the no-auth web console with an nginx reverse proxy and HTTP basic auth on port 80, persists all segments and metadata on a dedicated Azure data disk, and generates a unique console login on the first boot of every VM. Backed by 24/7 expert support.

Single-Server, Batteries Included

The image runs the bundled single-server profile so a customer gets a complete Druid cluster on one VM: an embedded Apache ZooKeeper, an embedded Derby metadata store and local-disk deep storage, all started automatically. bin/start-druid auto-sizes the JVM heaps to the VM, so Druid is ready to ingest and query without manual tuning.

Dedicated Data Disk

All persistent state, the deep-storage segments, the Derby metadata store, the ZooKeeper data and the indexing task logs, lives on a dedicated, independently resizable Azure data disk mounted at /var/lib/druid, separate from the OS disk and re-provisioned with every VM. Snapshot it to back up your ingested data and cluster metadata.

Secure By Default

The Druid web console has no native authentication, so every Druid service binds to loopback and an nginx reverse proxy enforces HTTP basic auth in front of it. A unique strong password for the admin console user is generated at first boot and stored in a root-only file, and only port 80 is exposed; front it with TLS for production.
