## Prefect on Ubuntu 24.04 LTS by cloudimg

Prefect is the modern Python workflow orchestration platform. Turn any Python function into an observable, schedulable workflow with retries, caching, concurrency limits and event-driven automation, and monitor every flow run, deployment and work pool from a rich web UI. It is the go-to tool for data engineers building and operating resilient data pipelines. The cloudimg image installs Prefect 3.7.5 in a dedicated Python virtualenv, runs the Prefect server as a systemd service bound to loopback behind an nginx reverse proxy on port 80 with HTTP Basic auth, persists orchestration state on a dedicated Azure data disk, and generates a unique login password on the first boot of every VM. Backed by 24/7 expert support.

Dedicated Data Disk

The Prefect home (PREFECT_HOME) and its SQLite database - flow runs, deployments and configuration - live on a dedicated, independently resizable Azure data disk mounted at /var/lib/prefect, separate from the OS disk and re-provisioned with every VM. Snapshot it to back up your orchestration history.

Secure By Default

Prefect Server has no built-in authentication, so the server is bound to loopback and nginx fronts it on port 80 with HTTP Basic auth. The per-VM admin password is unique to each VM, generated on first boot and stored in a root-only file. Front the proxy with TLS for production.
