eriklupander / go-microservice-eureka

Sample golang project with a simple http service exposing itself by registering with Eureka.

A sample go microservice with Eureka integration

This very simplistic little http service provides hard-coded 'vendors' on /vendors/{id} and is used as an example project for a blog post on http://callistaenterprise.se/blogg/teknik/

Building

Go SDK 1.5+ installed.

Clone this repo, set your GOPATH / GOROOT to the folder you cloned into.

cd src/github.com/eriklupander/go-eureka/*.go
go get

The docker image can be built using the .sh script:

#!/usr/bin/env bash

export GOARCH=amd64
export GOOS=linux
go build -o bin/goeureka src/github.com/eriklupander/goeureka/*.go
docker build -t vendor .
export GOARCH=amd64
export GOOS=darwin

Update for your target OS accordingly.

Running

This microservice can be ran standalone, though it will keep trying to contact the Eureka server at http://192.168.99.100:8761 until exit or success. I.e - this code is meant to be executed in the context of the blog post.

Anyway - you can hopefully start it using go run:

 > go run src/github.com/eriklupander/go-eureka/*.go

Have fun!
