Overview

SkyLB: an external gRPC load balancer based on SkyDNS. The design follows the gRPC Load Balancer Architecture (https://github.com/grpc/grpc/blob/master/doc/load-balancing.md). SkyLB can be used both in and out of Kubernetes.

Developer Guide

Prepare Source Code

$ git clone https://github.com/binchencoder/skylb.git

Build with Bazel

$ bazel build skylb/...

Start Dev Run with Docker Compose

Docker compose is our recommended way to start dev run of SkyLB. So first make sure you installed docker and docker compose on your machine.

Check out our docker projects:

$ sc track bld_tools/docker/etcd
$ sc track bld_tools/docker/ubuntu

Next you should download Ubuntu base package ubuntu-base-16.04-core-amd64.tar from www.ubuntu.com (as described in bld_tools/docker/ubuntu/BUILD) and put it in folder bld_tools/docker/ubuntu.

Run the following command to build docker images:

(bazel version must be >= 0.4.4 in order for docker-compose to work properly)

$ bazel run bld_tools/docker/etcd:latest
$ bazel run skylb/cmd/skylb:latest
$ bazel run skylb/cmd/webserver:latest

Run docker compose to start the dev run:

$ docker-compose -f docker-compose/dev/skylb/docker-compose.yml up
