Temporal on Ubuntu 24.04 | cloudimg

Temporal is an open source durable execution engine. Your application defines Workflows and Activities and runs them against the Temporal server, which persists every execution's full event history so work survives process and host failures and resumes exactly where it left off, with no bespoke retry, queue or state machine code.

This cloudimg image ships the MIT licensed Temporal server and its MIT licensed Web UI, backed by a bundled PostgreSQL 16 database, run the officially supported way as upstream containers orchestrated by Docker Compose under systemd on Ubuntu 24.04 LTS. All images are pinned by digest and captured into the VM, so your instance starts in seconds. The Temporal frontend and the bundled PostgreSQL are bound to the loopback interface only; PostgreSQL is never exposed on a host port.

Temporal's open source Web UI has no built in authentication, so cloudimg fronts it with nginx HTTP Basic Auth using a unique bcrypt password generated automatically the first time your VM boots, before the port is reachable, and recorded in a root only file. No default or shared credential ever ships. A unique database password is generated the same way, and the database starts freshly initialised with a pre registered default namespace and no prior data.

The cloudimg charge covers packaging, security patching, image maintenance and 24/7 expert support. Temporal is licensed under the permissive MIT license and is free to use. Use the Web UI to browse namespaces, workflows, event history and schedules, and point your own Temporal SDK workers at the server. See the deployment guide for the full setup walkthrough.
