Apache DolphinScheduler on Ubuntu 24.04 LTS by cloudimg

## Apache DolphinScheduler on Ubuntu 24.04 LTS by cloudimg

Apache DolphinScheduler is a distributed, easy-to-extend visual workflow scheduler for big data and ETL pipelines. You design DAGs of tasks (shell, SQL, Spark, Flink, Python, HTTP and more) in a drag-and-drop editor, schedule them with cron expressions, and monitor every run with retries, alerts and lineage. This cloudimg image installs DolphinScheduler 3.4.2 as the all-in-one standalone server (master, worker, API, alert server and the web UI in a single Java 17 JVM) behind an nginx reverse proxy on port 80, with all state on a dedicated Azure data disk and a unique admin password rotated on the first boot of every VM. Backed by 24/7 expert support.

Visual Workflow Scheduling

Design DAGs of shell, SQL, Spark, Flink, Python and HTTP tasks in a drag-and-drop editor, schedule them with cron, and monitor every run with retries, alerts and lineage.

All-in-One Standalone

The master, worker, API server, alert server and the React web UI run in a single Java 17 JVM, bound to loopback and fronted by nginx on port 80.

Dedicated Data Disk

All state - the bundled database, the workflow repository and run history - lives on a dedicated, independently resizable Azure data disk mounted at /var/lib/dolphinscheduler, separate from the OS disk and re-provisioned with every VM.

Secure First Boot

DolphinScheduler enforces its own username/password authentication; the shipped default admin password is rotated to a unique per-VM value on the first boot of every VM and written to a root-only file.

Getting Started

Deploy from the Azure Marketplace or the Azure CLI, open port 80, then read the admin password from /root/apache-dolphinscheduler-credentials.txt and sign in at http://your-vm-ip/. The web UI serves plain HTTP on port 80 - front it with TLS and your own domain before production.

Use Cases

Big-data and ETL workflow orchestration, scheduled DAG pipelines, data engineering job scheduling, and a self-hosted visual alternative to hosted schedulers.
