Apache StreamPark on Ubuntu 24.04 by cloudimg

Apache StreamPark is a streaming application development framework and a one stop management console for Apache Flink. This cloudimg image bundles StreamPark 2.1.7 together with a co located Apache Flink 1.20.5 standalone session cluster on the same host, so it is a complete, self contained StreamPark workbench that manages a real, running Flink cluster the moment the instance boots. It is purpose built for Microsoft Azure, hardened, security patched, and validated before publication, and backed by 24/7 expert support.

StreamPark runs as a Spring Boot service behind an nginx reverse proxy on port 80. StreamPark ships a well known default administrator, so this image is secure by default: the console binds to loopback, the public port stays shut, and on the first boot of every instance a one shot service rotates the admin password to a value unique to that instance, proves the default is rejected, and stores the new password in a root only file before opening the port. The Flink cluster binds to loopback only and is never exposed to the network, so only ports 22 and 80 need to be opened.

From the browser you can author, configure, deploy and monitor streaming applications, register and manage Flink runtimes and clusters, and track application state. The co located Flink cluster is registered in the console and shown running on first boot, so StreamPark is wired to a real cluster straight away. The base is Ubuntu 24.04 LTS with the latest security patches and unattended security upgrades enabled.
