proteus-quickstart

This project provides a scaffolding for getting up and running quickly with Netifi Proteus.

The project comes with a simple client and service. The client sends the word World to the service and the service responds with the message Hello, World! from {service name}.

Prerequisites

This quickstart requires the following:

1. Java Development Kit 8: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

2. Protocol Buffers Compiler

   You can download the compiler from here: https://github.com/google/protobuf/releases

   OR

   If you are on a mac using homebrew you can install it with the following command:

    $ brew install protobuf
   

3. A running instance of the Netifi Proteus Router

   You can start a single node cluster with Docker using the following command:

    $ docker run -p 8001:8001 -p 7001:7001 -e MEMBERS_ADDRESS=172.17.0.2:7001 -e CLUSTER_PUBLIC_ADDRESS=172.17.0.2:7001 -e CLUSTER_ADDRESS=172.17.0.2 -e ROUTER_ADDRESS=172.17.0.2 netifi/proteus
   

   Note the ports that are currently being assigned. You may need to modify them on your machine. If you modify the ports you will need to change them in the client and service.

Running the Quickstart

The instructions below start two instances of the example service and requests from the client are automatically load balanced between the service instances.

1. Validate that the Proteus Router is running.

   Check the console for a successful start message:

    2017-12-03 21:36:04,067 INFO i.n.r.Bootstrap [main] Router started in 2266.12 milliseconds
   

2. Start the first instance of the service using the following Gradle command:

    $ ./gradlew :service:run
   

3. In a new terminal, start the second instance of the service using the same Gradle command.

    $ ./gradlew :service:run
   

4. Start the client using the following Gradle command:

    $ ./gradlew :client:run
   

5. If the client successfully called the service and received a response you will see the following in the console:

    > Task :client:run
    SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
    SLF4J: Defaulting to no-operation (NOP) logger implementation
    SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
    Sending 'World' to HelloService...
    message: "Hello, World! from helloservice-a90a4fc7-74a3-4019-9263-3116332c5aed"
    
    
    
    BUILD SUCCESSFUL in 1s
    8 actionable tasks: 1 executed, 7 up-to-date
   

6. Run the client multiple times to see the requests load balanced between the service instances.
