Spring Boot Admin on Ubuntu 24.04 by cloudimg

Spring Boot Admin is an open source console for monitoring and managing Spring Boot applications through their Spring Boot Actuator endpoints. This cloudimg image builds a ready to run Spring Boot Admin 4.1 server, runs it on OpenJDK 21, and registers it against itself, so a live monitored application appears on the dashboard 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.

The console runs as a Spring Boot service behind an nginx reverse proxy on port 80, with Spring Security form login enabled by default. There is no shipped default login: a per VM administrator password is generated on the first boot of every instance and stored in a root only file, so no known or blank credential authenticates. The application and all actuator endpoints bind to the loopback interface, so only ports 22 and 80 need to be opened.

From the browser you can watch application and instance health, read metrics and JVM internals, inspect the environment, and change log levels on a running application without a restart. Connect your own services by adding the Spring Boot Admin client to them and pointing it at this server. The base is Ubuntu 24.04 LTS with unattended security upgrades enabled.
