Netflix Eureka Server on Ubuntu 24.04 LTS
Azure
Application Infrastructure
Netflix Eureka, the service discovery server that lets your microservices register themselves and find each other through one always on registry.
Overview
Netflix Eureka is an open source service registry for microservices. Each service instance registers itself with Eureka on start up, sends a regular heartbeat while it is healthy, and is removed when it goes away, so the registry always holds a current picture of what is running and where. Other services then look an instance up by its logical name rather than a hard coded address, which is what makes client side load balancing, failover and elastic scaling practical in a distributed system.
This is a standalone single node Eureka server: the registry itself, a web dashboard that lists every registered application and instance, and the REST registration API that clients talk to. It is the classic discovery backbone for a Spring Cloud or microservices platform, giving your services one well known place to find each other without wiring addresses by hand or standing up heavier infrastructure.
Why the cloudimg image
Netflix Eureka serves its dashboard and its registration API with no authentication at all, so cloudimg never exposes it unprotected: the server is bound to the loopback interface and reached only through a reverse proxy that demands a password, and both the dashboard and the registration API sit behind that wall. The admin password is generated fresh on every instance at first boot and written to a file only root can read, so nothing usable is baked into the image and no two instances share a secret, and the server is held back from serving until that per instance credential exists. Every deployment ships fully patched with unattended security upgrades left enabled, and comes with a paired step by step deploy guide backed by 24/7 cloudimg support.
Common uses
- Give your microservices a central registry so they can discover and call each other by name
- Run a standalone service registry as the discovery backbone of a Spring Cloud platform
- Enable client side load balancing and failover by resolving healthy instances from the registry
