Network Service Mesh examples repo

Network Service Mesh Examples

This repository contains examples and use-cases for Network Service Mesh. It is an independent way to deploy both NSM and a selection of examples, superimposed over the original networkservicemesh repository.

Quick Start

Control where NSM code is with NSM_PATH

The main cluster and infrastructure deployment targets are executed straight from the upstream networkservicemesh repository. The path to it is set by the environment NSM_PATH, with a default value of ../networkservicemesh. The easiest way to use it is to download both networkservicemesh and examples in the same root folder and then follow the next instructions.

Run the examples

In the examples repository folder, execute the following set of commands. These commands are for the proxy example. Change the term "proxy" for other examples:

make vagrant-start

. ./scripts/vagrant.sh

make k8s-infra-deploy

make k8s-proxy-save k8s-proxy-load-images

make k8s-proxy-deploy

make k8s-proxy-check

More details

The repo follows the main NSM development and deployment model based on Vagrant. Please refer to NSM's QUICK-START.md for detailed instructions on how to set-up the development environment.

Cluster setup

By default, the cluster is deployed with Vagrant using the following make target:

make vagrant-start

And then initialize the Kubernetes cluster access with:

. ./scripts/vagrant.sh

NSM infra deployment

NSM's core components are started as DaemonSets. By default all the images are downloaded off the official Dockerhub of the project.

make k8s-infra-deploy

If there is a need to run a particular version of the NSM, checkout the code under NSM_PATH and then ensure the containers are built and loaded. Run these commands in examples and after the Kubernetes cluster is initialized:

make k8s-save k8s-load-images
