Cilium clustermesh testing

This repo is a fork of bmcustodio/kind-cilium-mesh.

Introduction

This project bootstraps a cluster mesh between kind clusters using Cilium which can be used for demo or testing purposes.

Each cluster in mesh has http echo server deployment that responds with pod and cluster name:

{"cluster": "Cluster3", "pod": "deathstar-6578784ddd-m7hk5"}

And clients that send requests to deployment service, collecting information about requests distribution across clusters and pods based on the server response.

Required tools

go
docker
docker-compose
kubectl
kind
cilium

Bootstrapping clustermesh

Don't forget to check system limits:

fs.file-max=5000000
fs.inotify.max_user_watches = 524288
fs.inotify.max_user_instances = 512

To bootstrap the cluster mesh, run

make up

Or manually (useful for troubleshooting):

make create_cluster_1
make create_cluster_2
make create_cluster_3
make enable_mesh_cluster_1
make enable_mesh_cluster_2
make enable_mesh_cluster_3
make connect_clusters_3
make build_deathstar_image
make build_tiefighter_image
make deploy_cluster_1
make deploy_cluster_2
make deploy_cluster_3

Note that clusters are running in kubeproxy-free mode.

Monitoring

Create prometheus and grafana containers:

make setup_monitoring

Grafana will be available at http://localhost:3000
