EyePi is designed to keep track of the microservices I have running on my Raspberry Pi, and to allow me to remotely start, stop, and modify their metadata. I started this project to learn more about my employer's tech stack, in particular using React, and also because I was sick of having to ssh into my pi every time something went wrong to figure out what happened. I plan to extend this project to notify me when a service dies unexpectedly, because I don't have any infrastructure to support that on my pi as currently set up.

The Java server connects to a Mongo database of services, and starts each one. It then listens for commands, either as raw JSON or as HTTP requests containing a JSON body.

The Server class creates a CommandHandler and listens for socket connections. When it receives a connection, it creates a ClientHandler that waits to receive commands. Each ClientHandler sends the command to the CommandHandler, which produces a response, and then writes the response to the socket.

There is a ServiceMonitor singleton which spawns and monitors processes using bash commands, and a DatabaseManager singleton which presents an interface to the database.

The Java backend is located in src/main/java/net/noneuclideangirl. To create the folders used for storing logs etc. as well as a base config file, run setup.sh. Building via Maven (mvn package) in the root folder will build the server jar; simply run with java -jar target/eye-pi-1.0-SNAPSHOT.jar.

The React frontend is located in client. To build and run, use npm start.
