Operaton, an open source BPMN workflow and DMN decision automation engine, ready on first boot.
Operaton is an open source, community driven workflow and decision automation engine (the continuation of Camunda 7). It executes BPMN 2.0 processes and DMN decision tables through a persistent process engine and ships the Cockpit, Tasklist and Admin web apps plus a full REST API. Teams use it to model, run and monitor business processes and automated decisions across their applications.
cloudimg ships Operaton hardened and fully patched on Ubuntu 24.04, with a bundled PostgreSQL for durable state and a unique admin password generated on first boot. The web apps and the REST API are locked down from the start (no default demo account, authentication required everywhere), and the image is supported 24/7.
