H2

Source: https://github.com/hailocab/H2
Website: https://www.hailoapp.com

A microservices framework that powers all of Hailo.

What's Missing

Currently, we are shipping a few compiled services, we aim to open source them once we have cleaned the source code up and pointed them to compile against this repository instead of our private forks. This covers:

Config service
Binding service
Dashboards
Gateway
http2rpc service
Login service
Discovery service
Web discovery service

Getting Started

Developing Services

To develop your own applications, or to take H2 for a spin, you will need to start by creating a working development environment, instructions can be found in the provisioning repository website.

API Documentation for the this repository can be found on godoc.org (https://godoc.org/github.com/hailocab/H2).

Packages

The packages consumed by this repository have been split into two repositories platform-layer and service-layer. These are the same packages that internal closed source applications use.

Our have been split into logical groups, the service layer repository handles most of the non functional requirements for our platform, as well as providing ways of talking to our shared infrastructure.

The platform layer handles the underlaying application structure, ensuring an application is built in similar ways consistently.

Example Application

We have included a small example application, which will tell you how many services are currently running on your development environment.

To build this service, it's as easy as go build (Note: To run this on the VM, you will need to cross compile the binary http://dave.cheney.net/2015/08/22/cross-compilation-with-go-1-5). Running the service locally, outside of the development environment, requires a set of environment variables to be set.

H2_RABBITMQ_URL value: amqp://guest:guest@<virtual machine ip>:5672
H2_CONFIG_SERVICE_ADDR value: http://<virtual machine ip>:8097
H2_CASSA_DEFAULT_ADDR value: <virtual machine ip>:9160

So you could end up with a command that looks like:

$ env \
  H2_RABBITMQ_URL=amqp://guest:guest@192.168.33.10:5672 \
  H2_CONFIG_SERVICE_ADDR=http://192.168.33.10:8097 \
  H2_CASSA_DEFAULT_ADDR=192.168.33.10:9160 \
  hello-world
