A microservice used for discovery of services with gRPC. Stela uses IPv6 multicast to allow for scalable, distributed discovery on premises. The project is named after the stone monuments of the same name.
- Distributed run one or many Stela instances on any number of computers.
- Subscriptions subscribe to service names to receive a stream of any services registered or deregistered with that name.
- Simple Stela is meant to be started quickly with little configuration. It only focuses on service registration.

Running stela nodes
By default communicates over gRPC
:3100 and IPv6 multicast
:31053. Start your first instance:
stela -cert /path/to/server.crt -key /path/to/server.key -ca /path/to/ca.crt
If the SSL files you wish to use are stored as
ca.crt in the directory where the command is issued, you can omit the
ca parameters. Alternatively you can use the
-insecure flag if you don't want to use SSL/TLS gRPC.
Start two other instances on the same computer.
stela -port 31001
stela -port 31002
Or start another instances on a different computer.
Services registered with any of the instances will be discoverable by all.

- API Example: Refer to
-ca string Path to the private key file for the server. (default "ca.crt") -cert string Path to the certificate file for the server. (default "server.crt") -insecure Disable SSL, allowing unenecrypted communication with this service. -key string Path to the private key file for the server. (default "server.key") -multicast int Port used to multicast to other stela members. (default 31053) -port int Port for stela's gRPC API. (default 31000) -serverName string The common name of the server you are connecting to. (default "Stela") -status Shows how many stela instances are currently running. *Only works if you are running a local stela instance. -version Prints current version
