Apache Ignite on Ubuntu 24.04 LTS by cloudimg

## Apache Ignite on Ubuntu 24.04 LTS

Apache Ignite is a distributed database and compute platform that combines in-memory performance with durable native persistence, exposing ANSI SQL, key-value, and compute APIs. This image is built and maintained by cloudimg on a hardened, fully patched Ubuntu 24.04 LTS base.

### What's included

• Apache Ignite 2.16 on OpenJDK 11, managed by systemd
• Native persistence enabled, with storage on a dedicated managed data disk
• Thin-client / JDBC SQL on port 10800, bound to loopback for security
• Ignite authentication enabled with a unique password generated on first boot (no shared default)
• Automatic security updates enabled

### Getting started

Retrieve the generated password with `sudo cat /root/ignite-credentials.txt`, then connect with the bundled SQL client: `bin/sqlline.sh -u 'jdbc:ignite:thin://127.0.0.1/' -n ignite -p `. Create tables, run SQL, or use the thin-client APIs from your application. The deployment guide on cloudimg.co.uk covers cluster activation, persistence, and day-2 operations.
